Women are underrepresented as sole and last authors in academic papers. Men self-cite their own work more than women, with a 6.7 percentage point gap. This gender gap in self-citation rates has risen sharply since the 1960s and 1970s, though it has evened out more in recent decades. Potential reasons for men's higher self-citation rates include evaluating their own abilities more positively, facing fewer sanctions for self-promotion, specializing more within academic fields, and publishing more papers earlier in their careers.

The document discusses issues with large organizations and proposes ways to make them more responsive. It notes that organizations often function more like machines than organisms, prioritizing stability over responsiveness to their environment. This makes it difficult for organizations to change course even when problems emerge. The document suggests viewing organizations more like organisms with senses, integrated parts, information sharing, and a purpose/meaning. It also advocates for more input types, feedback loops, peer accountability and clarified missions to encourage quality, responsiveness and positive change. Heroes and catalysts are needed to drive such reforms within organizations.
Climate challenges and climate solutions
This document discusses the impacts of climate change and potential solutions. It summarizes findings that global temperatures have risen 1 degree Celsius over the past century and 2015 set a new record high. The Great Barrier Reef experienced severe bleaching and death of corals from El Nino effects and climate change. Examples are given of projects at Georgia Tech that have significantly reduced carbon emissions, like installing more efficient lighting and a cool roof. The document advocates accelerating shifts to low-carbon choices and using professional positions to drive climate solutions, while also lobbying leaders to take climate action such as a carbon fee and dividend program.
Water in North America: Past, Present and Future
1. We need to be realistic that our ability to predict future hydrological systems is limited, especially over long time periods.
2. Making decisions solely based on recent history fails to account for potential water-related surprises, like flooding or drought.
3. While some regions may be more vulnerable to climate change impacts on water resources, changes could still indirectly affect other areas.

This document discusses how studying tree rings and environmental history can help with managing resources and risks related to water and climate. It provides three key points:
1) Tree rings and other climate proxies like lake sediments and ice cores provide information about past climate variability like droughts, floods, and shifts in atmospheric patterns over centuries. This helps understand the range of natural climate variations.
2) Reconstructions of past river flows and floods indicate that some past events were more extreme than what modern records show, challenging assumptions about water availability and flood risks. This provides "stress tests" for water resource systems.
3) Decadal-scale climate patterns like the Pacific Decadal Oscillation cause important swings in precipitation

A paleoclimatologist's view of historical climate data
This document discusses physical paleoclimatology and the use of historical climate data. It provides examples of different types of proxy climate records like tree rings and historical documents that can be used to reconstruct past climate variables like temperature and precipitation over different time periods. It acknowledges some of the challenges with these data like dating accuracy and validating climate relationships with proxies. It also suggests priorities for expanding historical climate data archives, like adding more Canadian data to improve coverage of paleoclimate reconstructions in North America.

GEOG5839.15, signal processing
This document discusses tree ring data and standardization techniques. It introduces the linear aggregate model of tree growth and its components. It describes downloading tree ring width data from several sites in New Mexico and the principle of detrending the raw ring width data. It recommends using the ARSTAN program and different detrending methods like horizontal line, negative exponential curve, and flexible splines to standardize the chronologies and compare the results.
Contemporary problems in ancient climates
This document discusses contemporary issues in reconstructing ancient climates from proxy data like tree rings. It notes that while tree ring data contains climate information, uncertainties exist in extracting climate signals due to non-climatic tree growth factors and noise in proxy records. Statistical methods are needed to combine multiple proxy records but must account for these issues to avoid overfitting. The document also explores using tree ring data to study decadal scale climate variability and whether proxies may amplify low frequency climate signals.
Expanding the window - the past, present, and future of Minnesota's water
Nearly all decisions about water in Minnesota relate either directly or indirectly to data collected by the state’s hydrological observing network. Because most gauges were installed in early 20th century, as a whole the network provides us with roughly a 100-year ‘window’ to estimate flood risks, develop worst-case scenarios for drought, and set maximum allowable withdrawals for aquifers. But when we rely exclusively on observations made during this relatively brief interval, we may inadvertently increase our exposure to hydrological ‘surprises’. In order to make sound decisions about water in Minnesota, we need to expand this window: into the past, drawing upon historical accounts and natural archives; and into the future, via projections from climate and hydrological models. By cultivating a broader perspective on hydrological variability and extremes across the state, we will be better prepared to ensure adequate water supplies and mitigate the impacts of future floods and droughts.

Trees as flood sensors
In many settings, trees growing on floodplains provide an important source of indirect evidence that may be used to infer the occurrence, extent, and magnitude of floods prior to direct observations. That evidence may take several forms, including external scars caused by abrasion or impact from floating debris, anatomical changes within the annual growth increment following prolonged stem or root inundation, or tilting or uprooting due to the hydraulic pressure of floodwaters. Likely the most useful characteristic of paleoflood studies based on floodplain trees is their relatively high temporal resolution and dating accuracy compared to most other methods. Dendrochronological methods can routinely date past floods to the year of their occurrence and, in rare cases, can estimate the timing of floods that occur during the growing season to within two weeks. This high degree of chronological control, which is surpassed only by that provided by direct observation or instrumentation, can be used to determine whether floods in separate watersheds were synchronous or offset by several years and test hypotheses that suppose linkages between extreme floods and specific forcing mechanisms. Furthermore, the wide geographic distribution of tree species with dateable rings combined with the broad suite of methods available to examine interconnections between floods and tree growth allow this style of paleoflood hydrology to be applied to many settings that are not suitable for techniques that depend on geological evidence. Future paleoflood research involving tree rings will need to strike a balance between improving our understanding of the biological and fluvial processes that link tree growth to past events, and providing answers to questions about flood dynamics and hazards that are needed to safeguard people and property from future floods.

The "Year Without A Summer" was not a year without a ring
The Tambora eruption of 1815 cooled the planet and caused the "Year Without A Summer" in western Europe and eastern North America. But was it cold enough to cause trees across the Northern Hemisphere to skip a ring?
Noah, Joseph, And High-Resolution Paleoclimatology
In 1968, Benoit Mandelbrot and James Wallis published an article titled ‘Noah, Joseph, and operational Hydrology’ in the journal Water Resources Research. In it, they argued that hydrological models of the day were not able to estimate the true risk of extreme floods or prolonged drought, and that rare hydrological events were much more common than usually assumed.
In this lecture, I’ll review how high-resolution paleoenvironmental archives can help us judge more accurately the risks posed by the ‘Noah’- and ‘Joseph’-style events described by Mandelbrot and Wallis. I’ll give particular emphasis to the environmental information recovered from the rings of ancient trees, and explain how dendrochronology (tree-ring research) has been used to redefine the ‘flood of record’, test potential avenues for long-lead climate predictions, and gage the performance of state-of-the-art climate models.
A Song of Our Warming Planet: Using Music to Communicate Critical Concepts in...
When climate science is communicated to the broader public, many of its key findings are shared in the form of conceptual diagrams or information-dense data graphics. In this collaboration, we applied a data sonification approach to express NASA’s global temperature record as a musical composition for the cello. The resulting piece, which we titled ‘A Song of Our Warming Planet’, transformed 133 years of annual global temperature anomalies into a haunting, atonal melody that stretched across almost all of the instrument’s range. Since its release in June 2013, the song has been featured by several national and international media outlets, including the New York Times, the Weather Channel, and National Public Radio, and its accompanying video has received more than 140,000 views from nearly every corner of the world. We are currently preparing a new composition for string quartet that will add a geographic dimension to describe both the pace and place of global warming. We believe the success of our initial sonification project is testament to the power of music to reach audiences who respond less enthusiastically to traditional methods used to communicate climate science. We also imagine this approach could be applied more broadly to allow students to create novel, visceral, and memorable encounters with other aspects of the geophysical sciences.
Large-scale dendrochronology and low-frequency climate variability
Large-scale low-frequency variability has emerged as a priority for climate research, but instrumental observations are not long enough to characterize this behavior or gage its impacts on dependent geophysical or ecological systems. As the leading source of high-resolution paleoclimate information in the middle- and high-latitudes, tree rings are essential to understand low-frequency variability prior to the instrumental period. But even though tree rings possess several advantages as climate proxies, like other natural archives they also have their own particular impediments. In this lecture, Dr. St. George will describe the structure and characteristics of the Northern Hemisphere tree-ring width network, and outline how the fingerprint of decadal and multidecadal climate variability encoded within ancient trees varies across the hemisphere.
Guarding against false discovery in large-scale dendroclimatology
Measurements of tree-ring widths are the most widely-distributed and best replicated source of surrogate environmental information on the planet, and are one of the main archives used to estimate changes in regional and global climate during the past several centuries or millennia. Because the Northern Hemisphere ring-width network is now so large, it is more crucial than ever to ensure our understanding of tree-environment relations is not influenced by decisions to include or exclude certain records. It may be the case that a particular set of ring-width records are, for whatever reason, more tightly coupled to a particular climate factor than other records from the same region or species and, as a result, may be superior estimators of that factor’s past behavior. At the same time, it is known that selecting a small number of predictors from a large pool of potential candidates increases the likelihood of a Type I error. That effect may be particularly relevant to dendroclimatology because the total number of available ring-width records is often much larger than the number of records used to produce reconstructions of large-scale climate features. As an initial step, it would be helpful if paleoclimate reconstructions derived from tree rings described more explicitly the criteria used to select ring-width records as potential predictors and specified those records excluded by that screening. By comparing ring-width chronologies and their relations with climate against the standard set by thousands of records across the hemisphere, we should be better able to distinguish climate signals from proxy noise and produce more accurate reconstructions of climate during the late Holocene.
Making Climate Data Sing
These visuals were prepared to support a string quartet performance and panel on climate change at Northwestern University in February 2106.
A well-designed graphic can help audiences to quickly understand the main message embedded within a complex set of climate data and to retain those ideas longer than they would have if they were conveyed by words alone. But the visual aids used regularly by climate scientists also have their limitations: they are most easily understood by people who are already fluent in technical illustrations; they're usually static and sometimes do not tell an obvious story; and for many, they don't elicit a strong emotional response.
Music, by contrast, is inherently narrative and is known to exert a powerful influence on human emotions. Because of this, sonification — the transformation of data into acoustic signals — may have considerable promise as a tool to enhance the communication of climate science.
Daniel Crawford and Scott St. George report on a collaboration between scientists and artists that uses music to transmit the evidence of climate change in an engaging and visceral way.

The ability to deliver effective and engaging oral presentations is a critical skill for all researchers. Unfortunately, despite the importance of clear communication, too many scientific presentations at conferences and workshops are confusing, abstract, and boring. In this short workshop, participants learn several key strategies and tips that will make their professional presentations just a little bit better than the rest. We discuss strategies for presentation planning, show how basic design principles can create more memorable slides, and point towards an outstanding set online tools and resources. Become a presentation superstar!
Scott St. George is Associate Professor in the Department of Geography, Environment and Society at the University of Minnesota and a Resident Fellow at UMN's Institute on the Environment. Prior to joining the faculty at Minnesota, he was a research scientist with the Geological Survey of Canada. Scott shares some of his experiences ‘doing presentations differently’ at conferences, outreach opportunities, and the classroom.
Decadal variability in tree rings
Strong variance at decadal and multidecadal timescales is a common feature of most tree-ring width records. But does this aspect of tree growth exhibit such long-memory behavior due to biology, climate, or some combination of the two factors? Understanding the origins of this behavior is crucial for efforts to evaluate the causes of decadal variability in the climate system.

Mathematics.ppt
This document discusses women in mathematics and some of the challenges they face. It provides statistics on the percentage of bachelor's and PhD degrees in math earned by women, as well as the low percentage of tenured positions in math departments held by women. It discusses research on cognitive differences between men and women in math and spatial abilities, and how these differences may be influenced by environment and stereotypes. The document also summarizes various studies on stereotype threat and how simply referring to gender before a math test can negatively impact women's performance. Overall, it examines some of the social and cultural factors that have created barriers for women in mathematics.
Women in Science
The document discusses reasons for the low percentage of women in physics careers. It notes that girls are less likely than boys to choose strong math programs in high school and scientific fields in university. Women physicists are also less likely to receive mentoring and support needed for career success compared to their male peers. However, the document argues that women can have highly successful physics careers if barriers are removed and family obligations are better supported through flexible work policies and funding opportunities.

Ginny Catania presented on improving belonging in Greenland science. She noted that the cryospheric sciences are dominated by men, with the AGU Cryosphere Section having 3 times more male than female members. Some reasons for this disparity include unconscious and conscious bias, a chilly academic climate, and unequal access to resources such as social support networks and funding opportunities. Examples were provided of ways in which bias manifests, such as overburden of service work, lack of mentorship and collaboration, and harassment. The presentation discussed how the university system and field of glaciology were historically designed to exclude women, and how notions of academic skill still emphasize outdoor experiences more common among men.

This document discusses improving belonging and representation in Greenland science. It summarizes that women and other minoritized groups are underrepresented in cryospheric sciences. Specifically, the AGU Cryosphere Sciences Section has 3 times more men than women. It explores reasons for this disparity, such as unconscious and conscious bias, a chilly academic climate, and unequal access to resources. The document outlines specific examples of how bias shows up, such as overburden of service work or lack of mentorship. It proposes that the research culture needs to change and discusses the impacts of academic culture on diversity. Finally, it summarizes the successes and challenges of a new Slack workspace community aimed at supporting underrepresented groups in glaciology and
The Computer Scientist and the Cleaner v4
This document summarizes a talk given by Ian Gent about gender balance in computer science. It discusses how unconscious biases can negatively impact women in the field. Through examples and images, it illustrates common stereotypes associated with gender roles. It also shares statistics demonstrating the lack of gender diversity among computer science faculty and professors. Finally, it provides recommendations for creating a more inclusive environment, such as avoiding biased language and disrespecting others. The overall message is that computer science would benefit from embracing people from all backgrounds.

The document discusses a study conducted on the factors contributing to female students outperforming male students academically at Jonathan Grant High School in Jamaica. It provides background information on the problem, reviews previous literature on the topic of male underperformance, describes the data collection methods used which included questionnaires distributed to students, and presents the results of the data collected. The results showed that social factors like musical distractions, lack of focus, and preference for work over school contributed to lower male academic performance according to the students.

It discusses research on cognitive differences between men and women in math and spatial abilities, and how these differences may be influenced by environment and stereotypes. The document also summarizes various studies on stereotype threat and how simply referring to gender before a math test can negatively impact women's performance. Overall, it examines some of the social and cultural factors that have created barriers for women in mathematics.
Women in Science
The document discusses reasons for the low percentage of women in physics careers. It notes that girls are less likely than boys to choose strong math programs in high school and scientific fields in university. Women physicists are also less likely to receive mentoring and support needed for career success compared to their male peers. However, the document argues that women can have highly successful physics careers if barriers are removed and family obligations are better supported through flexible work policies and funding opportunities.

Ginny Catania presented on improving belonging in Greenland science. She noted that the cryospheric sciences are dominated by men, with the AGU Cryosphere Section having 3 times more male than female members. Some reasons for this disparity include unconscious and conscious bias, a chilly academic climate, and unequal access to resources such as social support networks and funding opportunities. Examples were provided of ways in which bias manifests, such as overburden of service work, lack of mentorship and collaboration, and harassment. The presentation discussed how the university system and field of glaciology were historically designed to exclude women, and how notions of academic skill still emphasize outdoor experiences more common among men.
Catania_inclusion.pdf
This document discusses improving belonging and representation in Greenland science. It summarizes that women and other minoritized groups are underrepresented in cryospheric sciences. Specifically, the AGU Cryosphere Sciences Section has 3 times more men than women. It explores reasons for this disparity, such as unconscious and conscious bias, a chilly academic climate, and unequal access to resources. The document outlines specific examples of how bias shows up, such as overburden of service work or lack of mentorship. It proposes that the research culture needs to change and discusses the impacts of academic culture on diversity. Finally, it summarizes the successes and challenges of a new Slack workspace community aimed at supporting underrepresented groups in glaciology and
The Computer Scientist and the Cleaner v4
This document summarizes a talk given by Ian Gent about gender balance in computer science. It discusses how unconscious biases can negatively impact women in the field. Through examples and images, it illustrates common stereotypes associated with gender roles. It also shares statistics demonstrating the lack of gender diversity among computer science faculty and professors. Finally, it provides recommendations for creating a more inclusive environment, such as avoiding biased language and disrespecting others. The overall message is that computer science would benefit from embracing people from all backgrounds.
Alex edit ia caribbean studies
The document discusses a study conducted on the factors contributing to female students outperforming male students academically at Jonathan Grant High School in Jamaica. It provides background information on the problem, reviews previous literature on the topic of male underperformance, describes the data collection methods used which included questionnaires distributed to students, and presents the results of the data collected. The results showed that social factors like musical distractions, lack of focus, and preference for work over school contributed to lower male academic performance according to the students.

The McGill University Biology Graduate Students Association invited Dean Imogen Coe & myself to talk about Unconscious or Implicit Bias in Science, Technology, Engineering and Mathematics. We had great session in Thompson House on 29 November 2016. Thank you Taylor Moulton and your fellow graduate students for creating the space for us to have this conversation. We not only discussed systemic bias faced by women, but also people of colour and other minority cultures.
MPACE Poster
This document discusses recommendations for recruiting and retaining women in STEM fields based on Bronfenbrenner's Ecological Model and strengths-based practice. It recommends considering the various environmental systems that influence women's behaviors according to Bronfenbrenner's model. Strengths-based practice involves focusing career counseling for women in STEM on identifying and building upon their strengths, talents, and accomplishments rather than perceived deficiencies. The document provides examples of applying these frameworks to different stakeholders involved in women's careers in STEM such as recruiters, educational institutions, and role models.
Fairness in Machine Learning @Codemotion
AI should be Fair, Accountable and Transparent (FAT* AI), hence it's crucial to raise awareness among these topics not only among machine learning practitioners but among the entire population, as ML systems can take life-changing decisions and influence our lives now more than ever.
THESIS-Victoria_Strelnikova_FINAL
This document presents a thesis exploring mentorship and retention of women in STEM fields. The introduction provides background on the underrepresentation of women in STEM jobs and degrees despite making up half the college-educated workforce. Key factors contributing to this discrepancy include lack of role models, gender stereotyping, and inflexible work environments. The purpose is to understand women's experiences in STEM and potential solutions. A literature review covers topics like gender stereotypes, career pathways, and the benefits of mentoring. The methodology section outlines a narrative study approach involving interviews with one woman in STEM. Overall, the thesis aims to gain insights into supporting greater participation of women in STEM.
Updated: My experience with tackling ongoing barriers faced by Women in STEM ...
Dawn Bazely discusses her experience advocating for women in STEM fields over several decades. She notes that while policies in the 1970s-90s aimed to increase the number of women in STEM, they failed to shift cultural norms due to unconscious biases. Recent research on implicit biases and social media movements like #MeToo have led to a greater awareness of barriers like harassment. Bazely emphasizes the importance of addressing retention, not just the pipeline, and highlights the role of social media in connecting advocates and applying pressure for policy changes to promote diversity and inclusion.
My experience with tackling ongoing barriers faced by Women in STEM in Canada
Talk for Women Studies, Visva Bharati University, Santiniketan, West Bengal, India. March 17, 2018.

Anne MacLachlan study
This document summarizes a study on the careers of minority women who earned PhDs in science and engineering from the University of California, Berkeley between 1980-1990. It finds that:
1) Of the 85 minority PhD holders from UC Berkeley in this time period, only 23 were women. The majority have built substantial careers, though few hold faculty positions at top research universities.
2) About 59% of the 56 minority PhD holders interviewed currently work in academic institutions, while others work for government labs, in the private sector, or other organizations. They are distributed across prestigious institutions.
3) Of the 19 women PhD holders interviewed, about one-third hold faculty or research positions while others work in government,
Starry Tales of Women, Men and Crocodiles
This document summarizes a presentation given by Dr. Rachel Morgain on International Women's Day about gender equity in astronomy. It discusses research showing implicit biases that associate science with masculinity. It also analyzes the naming of exoplanets, finding most were named for male mythical or historical figures from European traditions. Two exceptions are planets in the Thai Crocodile constellation named for sisters in a folktale. The single female historical figure honored was Hypatia, an influential astronomer and philosopher murdered in 415 AD. The document concludes by summarizing research on gender depictions of scientist characters in the long-running TV series Doctor Who.
US-Delegation-Poster-08-01-2014-2
This document summarizes efforts in the United States to improve recruitment and retention of women in physics. It provides data on the low percentage of women currently in physics fields and programs that have been established, including conferences, mentoring programs, professional development workshops, media coverage, and government initiatives, to encourage more women to enter and remain in physics careers.

Debiasing Knowledge Graphs: Why Female Presidents are not like Female Popes
The document discusses biases that can exist in knowledge graphs, including data biases from uneven coverage, schema biases from how ontologies are constructed, and inferential biases from how rules are learned. It provides examples of each, such as more data about some regions than others, modeling concepts from a limited perspective, and rules learned from data that could promote harmful stereotypes. The document argues that debiasing knowledge graphs is an important research topic, but also raises open questions about how to technically approach debiasing and whether approaches aim to truly address biases or just hide problems.

Cobb Centre College, October 2019
This document discusses the impacts of climate change and actions that can be taken to address it. It provides graphs showing rising global temperatures and impacts like coral bleaching. It emphasizes the need to urgently reduce emissions through solutions like renewable energy and energy efficiency. Individual actions are suggested like reducing flights and increasing tree planting, but it also stresses the importance of collective action through institutions and elected leaders enacting climate policy.
Carbon Reduction Challenge - overview
The Carbon Reduction Challenge is a program run by Georgia Tech that educates students to become climate literacy ambassadors. Students learn about climate change, identify a carbon reduction project at their university, quantify the carbon savings and cost savings, and pitch their project. The program has grown over time, with more participating universities completing projects that have avoided over 40 million pounds of CO2 emissions. It helps students gain skills in translating climate science into practical solutions.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
