This study analyzed the impact of abrupt dryness incidents on forest productivity at two forest sites in Switzerland over a period of 17-23 years. The researchers found that forest net ecosystem productivity (NEP) decreased by around 9-10% during periods of abrupt dryness compared to normal weather conditions. Additionally, the sub-alpine coniferous forest site showed higher resistance to abrupt dryness than the montane mixed forest site. An analysis of weather data across Europe from 1970 to 2020 found that occurrences of sudden weather changes have increased over the last 50 years.

This document discusses creating an icing climatology using downscaling techniques from a weather modeling project. It examines modeling icing events and ice loads, and comparing modeled results to measurements which sometimes show large differences. Two approaches to the climatology are considered: statistically downscaling long-term low-resolution model runs, or modeling shorter representative periods at high resolution. Both have advantages and drawbacks regarding accuracy and representation of climatological conditions. More research is needed to determine the best approach.

This document analyzes ecosystem functioning and recovery after extreme drought years in 2018 and 2019 in Switzerland using data from two long-term eddy covariance measurement sites. It finds that atmospheric and soil dryness were more severe in the low-elevation mixed forest in 2018 but more severe in the high-elevation coniferous forest in 2019. Both forests showed reductions in net carbon uptake during drought, though the low-elevation forest was more impacted. The coniferous forest also demonstrated a stronger physiological response to drought and a larger increase in water use efficiency. Overall, the years 2018 and 2019 had similar effects on ecosystem carbon uptake.Drought Assessment + Impacts: A Preview

Evaluating aboveground terrestrial carbon flux as ecosystem planning
This document evaluates using terrestrial carbon flux estimation models as ecosystem planning tools for the Mt. Kenya ecosystem. It summarizes using the Carnegie Ames Stanford Approach (CASA) model to estimate net primary production and carbon assimilation potential in Mt. Kenya vegetation using Landsat imagery. Key findings include that CASA can capture landscape variability in carbon flux, satellite-derived vegetation indices like EVI are useful for accounting for carbon sinks, and indigenous species show more resilience than agricultural lands, which have potential for increased carbon sequestration. The study also analyzes human appropriation of net primary production across river basins to inform river basin planning.

This document analyzes the climate of the Petrie Creek catchment in Australia using simulation data from 1960-2010. It finds that the mean annual precipitation is 1719.09 mm, with higher rainfall in summer months. The mean annual temperature increased from 18.84 to 19.80 degrees Celsius over this period. Analysis of extremes found the highest daily rainfall was 702.4 mm in 1992. Climate change may increase temperatures and decrease rainfall in the catchment, requiring further study of impacts on flooding and infrastructure. More comprehensive climate data analysis is needed to fully understand trends and impacts on similar catchments.

The document summarizes research on an eco-hydrological model to investigate how trees maintain carbon assimilation and water fluxes during drought through deep fine root development. The model was calibrated and validated for deciduous and evergreen tree sites in Germany and France. Simulation results showed the hypothetical root mechanism allowed for higher net carbon profit and carbon assimilation during drought through extracting water from deeper soil layers.

This master's thesis evaluates the open stormwater solutions in Augustenborg Eco-city, Sweden using a hydrological model. Augustenborg is known for its sustainable planning and effective open stormwater systems. The study aims to investigate the efficiency of the open stormwater system during extreme rainfall events. A MIKE SHE model is built to simulate 1-year, 10-year, and 100-year extreme rainfall scenarios. The results show that the open stormwater solutions perform well under normal conditions and 10-year events but flooding may occur under a 100-year event if the soil becomes saturated. The thesis concludes that the current system is suitable for handling typical climatic conditions but identifies risks during extreme events.

Abstract— In this article four global gridded datasets of the Standardized Precipitation Index (SPI) are presented. They are computed from four different data sources: UDEL/GEOG/CCR v3.02, GPCC/ v7.0, NOAA-CIRES 20CR v2c and ECMWF ERA-20C each covering more than a century-long period. The SPI is calculated for the most frequently used time windows of 1, 3, 6, and 12 months. UDEL/GEOG/CCR v3.02 and GPCC/ v7.0 are used in the highest native resolution of 0.5×0.5° whilst NOAA-CIRES 20CR v2c and ECMWF ERA-20C are interpolated at 1.5×1.5° and 0.5×0.5° correspondingly. In contrast to some other indices, for example the popular Palmer Drought Severity Index (PDSI), SPI has significant advantages such as simplicity, suitability on variable time scales and robustness rooted in a solid theoretical development. SPI has been selected by the World Meteorological Organization (WMO) as a key indicator for monitoring drought ('Lincoln declaration'). As a result, drought monitoring centres worldwide are effectively exploiting this index and the National Meteorological and Hydrological Services (NMHSs) are encouraged to use it for monitoring meteorological droughts. These facts and the strong conviction of the authors that the free exchange of data and software services are а basis of effective scientific collaboration, are the main motivators to provide these datasets free of charge at ftp://xeo.cfd.meteo.bg/SPI/. The paper briefly presents some possible applications of the SPI data, revealing its suitability for various objective long-term drought studies at any geographical location.Floodplain forest greenhouse gas fluxes in changing climate

Land and climate Key messages for students
This document summarizes key messages from an IPCC report on land and climate. It notes that global warming is already occurring across continents and oceans, affecting both rich and poor countries. While some solutions involve better land management, land alone cannot solve the problem as energy production is the primary driver of greenhouse gas emissions. The document calls for coordinated responses including science-based decision making, spatial planning, measures to reduce emissions from food production, and both near-term adaptation and long-term mitigation efforts across all sectors to minimize impacts on land systems and enable ecological restoration.

Twenty years of evapotranspiration measurements over a sub-alpine coniferous ...Integrated Carbon Observation System (ICOS)
The document summarizes 20 years of evapotranspiration measurements over a sub-alpine coniferous forest in Switzerland. It finds that actual evapotranspiration has significantly decreased over the last two decades, diverging from increasing potential evapotranspiration, despite rising vapor pressure deficit and declining precipitation. This suggests stomatal acclimation to increasing water use efficiency as a plastic response to changing conditions. Carbon uptake has increased over the same period, demonstrating changing physiological feedback to the atmosphere with less evaporative cooling effect.Monitoring Global Biome Dynamics from Space
Remote sensing of the environment and Earth observation sciences are relatively young research domains that are highly interdisciplinary, combining expertise in biology, ecology, geography, physics, and computing science. Combining data from space-based and airborne sensors with traditional field observations provides powerful insights on how different ecosystems function and what drives changes in them at a global scale. With the turn of the 21st century we have seen a major expansion of our Earth observation capabilities with hundreds of new satellite systems in orbit around our planet and a myriad of new environmental sensor systems at the surface keeping an eye on how our planet is changing and how those changes influence our societies.
This presentation reviews the basics of remote sensing of vegetation biophysics for ecology and environmental monitoring and explores in greater depth how we can use these new technologies to better understand how more sensitive ecosystems respond to global change forces and can act as canaries in the coal mine for the early detection of climate change risks. I will also discuss how our research capabilities in this field are changing with the start-up of commercial aerospace agencies, the ever-decreasing size and cost of consumer electronics, and the emergence of affordable unmanned aerial vehicles, or ‘drones’.
Country experiences: Lesotho
Lesotho is developing climate change scenarios to help plan for risks and vulnerabilities. A national team is using daily temperature and rainfall data from 1951-2100 from several global climate models to generate projections under two emission scenarios. Products developed so far include maps of historical climate averages and trends, as well as projected changes in averages for different time periods and climate extremes indices important to sectors like agriculture. Lesotho hopes these scenarios will help prepare for increased temperature, altered precipitation patterns, and more frequent extreme weather events under climate change. Developing the scenarios with local experts is building national capacity, though higher resolution data may better capture Lesotho's complex terrain.

Drought Monitoring and Early Warning Indicators by Lucka Bogataj, University ...Global Water Partnership Central and Eastern Europe
Drought monitoring and early warning indicators can help countries adapt to climate change. Three key types of water problems in Central and Eastern Europe may be exacerbated by climate change: too little water, too much water, and water pollution. Effective drought monitoring requires assessing multiple indicators like precipitation, soil moisture, streamflow, groundwater, and vegetation health across different timescales. A consensus approach uses a combination of standardized precipitation, soil moisture, and vegetation indices. Developing an integrated drought monitoring system can help shift from reactive to risk-based drought management and increase resilience to climate change impacts.Climate resilient crop cultivars in the view point of physiology and genetics...

This document summarizes the ClimBar project which aims to evaluate genetic diversity in barley to support climate adaptation. The project recognizes that barley varieties were domesticated under different past climates than current emerging conditions. It hypothesizes that alleles supporting resilient yields in a changing climate may be found in diverse landraces from the Mediterranean and Fertile Crescent, which experienced climates similar to projections. The project is phenotyping a diverse set of barley accessions, including Spanish landraces and wild barleys, under different environments to understand genotype by environment interactions over time and identify useful alleles for future climate breeding.Dr Andrew Rawson: Soil Carbon Sequestration in a Changing Climate
Dr Andrew Rawson of the NSW Department of the Environment and Climate Change, explains why climate change is blamed for more than it can be held to have caused. This presentation was given at the Carbon farming Expo & Conference in Orange NSW Australia in November 2008.
Renewable energy resources_ climate change perspective
The document discusses renewable energy resources and climate change from an environmental perspective. It begins by defining climate change and the greenhouse effect, noting that human activities like burning fossil fuels have increased greenhouse gas concentrations and led to global warming. It then discusses key greenhouse gases like carbon dioxide, and how human activities have impacted the natural balance of carbon sinks and sources. The document also addresses the adverse effects of climate change, like increased extreme weather events and sea level rise. It emphasizes that transitioning to renewable resources is needed to mitigate the risks of climate change.

I will also discuss how our research capabilities in this field are changing with the start-up of commercial aerospace agencies, the ever-decreasing size and cost of consumer electronics, and the emergence of affordable unmanned aerial vehicles, or ‘drones’.
Country experiences: Lesotho
Lesotho is developing climate change scenarios to help plan for risks and vulnerabilities. A national team is using daily temperature and rainfall data from 1951-2100 from several global climate models to generate projections under two emission scenarios. Products developed so far include maps of historical climate averages and trends, as well as projected changes in averages for different time periods and climate extremes indices important to sectors like agriculture. Lesotho hopes these scenarios will help prepare for increased temperature, altered precipitation patterns, and more frequent extreme weather events under climate change. Developing the scenarios with local experts is building national capacity, though higher resolution data may better capture Lesotho's complex terrain.

Drought Monitoring and Early Warning Indicators by Lucka Bogataj, University ...Global Water Partnership Central and Eastern Europe
Drought monitoring and early warning indicators can help countries adapt to climate change. Three key types of water problems in Central and Eastern Europe may be exacerbated by climate change: too little water, too much water, and water pollution. Effective drought monitoring requires assessing multiple indicators like precipitation, soil moisture, streamflow, groundwater, and vegetation health across different timescales. A consensus approach uses a combination of standardized precipitation, soil moisture, and vegetation indices. Developing an integrated drought monitoring system can help shift from reactive to risk-based drought management and increase resilience to climate change impacts.Climate resilient crop cultivars in the view point of physiology and genetics...

This document summarizes the ClimBar project which aims to evaluate genetic diversity in barley to support climate adaptation. The project recognizes that barley varieties were domesticated under different past climates than current emerging conditions. It hypothesizes that alleles supporting resilient yields in a changing climate may be found in diverse landraces from the Mediterranean and Fertile Crescent, which experienced climates similar to projections. The project is phenotyping a diverse set of barley accessions, including Spanish landraces and wild barleys, under different environments to understand genotype by environment interactions over time and identify useful alleles for future climate breeding.Dr Andrew Rawson: Soil Carbon Sequestration in a Changing Climate
Dr Andrew Rawson of the NSW Department of the Environment and Climate Change, explains why climate change is blamed for more than it can be held to have caused. This presentation was given at the Carbon farming Expo & Conference in Orange NSW Australia in November 2008.
Renewable energy resources_ climate change perspective
The document discusses renewable energy resources and climate change from an environmental perspective. It begins by defining climate change and the greenhouse effect, noting that human activities like burning fossil fuels have increased greenhouse gas concentrations and led to global warming. It then discusses key greenhouse gases like carbon dioxide, and how human activities have impacted the natural balance of carbon sinks and sources. The document also addresses the adverse effects of climate change, like increased extreme weather events and sea level rise. It emphasizes that transitioning to renewable resources is needed to mitigate the risks of climate change.

Jocher, Georg: Addressing forest canopy decoupling on a global scaleIntegrated Carbon Observation System (ICOS)
This document discusses addressing forest canopy decoupling on a global scale. It provides background on decoupling, which occurs when there is insufficient mixing of air masses above and below the forest canopy. This can bias carbon flux measurements made above the canopy. The document outlines a global decoupling synthesis study involving over 30 forest sites. Preliminary results show decoupling occurs at all sites and is influenced by atmospheric conditions, canopy properties, and surrounding topography. Topography in particular can impact flow patterns and cause horizontal advection during decoupled periods. In conclusion, complementary below-canopy measurements are recommended to better understand decoupling and its effects on carbon flux estimates.Dukat, Paulina: How does drought impact water and carbon exchange in the temp...

This study examined how drought impacts water and carbon exchange in Scots pine forests across boreal and temperate climate zones. The researchers used the Standardized Precipitation Evapotranspiration Index (SPEI) to determine drought conditions at six Scots pine forest sites representing a range of climates. They found that prolonged drought, even over multiple summers, reduced the carbon uptake and increased the water use efficiency of the pine forests. Specifically, they observed a reduction in the assimilation rate and annual carbon sequestration at one temperate forest site after an extreme drought in 2015. Linking long-term SPEI data to on-site flux and soil measurements helped explain the forest ecosystem responses to drought across different climaticvan Zwieten, Ruthger: Performance assessment of the mobile g4301 Cavity Ring-...

This document describes methods to improve machine learning reconstructions of ocean carbon dioxide (pCO2) by incorporating physical knowledge. It presents two methods: (1) reconstructing the pCO2 residual by removing the temperature component, focusing the model on other drivers; and (2) using ocean biogeochemical models as a prior and training a machine learning model to estimate the climatological misfit between models and observations, allowing extension of reconstructions back to 1959. Both methods showed improved performance over original models in independent evaluation data, with the climatological correction approach capturing most of the improvement. The techniques demonstrate how physical knowledge can enhance machine learning reconstructions of pCO2.Kowalska, Natalia: Does Below-Above Canopy Air Mass Decoupling Impact Tempera...

This document presents research on the impact of below-canopy and above-canopy air mass decoupling on carbon dioxide exchange in a temperate floodplain forest. The study measured CO2 fluxes above and below the forest canopy from 2015-2020 at a site in Lanžhot, Czech Republic. While decoupling between the layers occurred regularly, the analysis found no significant effect of decoupling on the annual net ecosystem carbon exchange derived from above-canopy measurements. The flat terrain around the study site likely inhibited the removal of carbon-rich air, minimizing any bias from decoupling over longer time scales.Cinelli, Giorgia: Use of outdoor radon activity concentration and radon flux ...

The document describes an investigation of the Suess effect in the surface waters of the Southern Indian Ocean between 1998 and 2021 using carbon isotope data. Key findings include:
1) Application of an extended multiple linear regression model to the data detected anthropogenic changes to both dissolved inorganic carbon and carbon isotope ratios, with a rate of increase in anthropogenic carbon of 0.8 μmol/kg/yr and rate of decrease in carbon isotope ratios (Suess effect) of 0.011‰/yr.
2) The rates of change estimated by the regression model were similar to rates estimated from observed regional trends over the study period, suggesting only small impacts from natural variability.
3) A strong linear relationship wasHavu, Minttu: Spatial variability of local carbon emissions and sinks in Hels...

This document summarizes a study estimating the spatial variability of carbon cycle components in Helsinki, Finland using the SUEWS modelling tool. The study found that CO2 emissions from human metabolism accounted for 45% of local anthropogenic emissions, while net biogenic CO2 exchange accounted for 25% of anthropogenic emissions. Spatial maps showed traffic emissions were concentrated along ring roads, building heating emissions in residential areas, and human metabolism emissions in city centers. Vegetation uptake and emissions from human metabolism were comparable to or exceeded emissions from traffic and building heating in some areas of Helsinki.Veerkamp, Hannes: Measurements of the CO2 gas transfer velocity in Jade Bay

This study measured CO2 fluxes and water turbulence in Jade Bay, Germany during winter to better understand how these parameters influence air-sea CO2 exchange. Researchers used a floating chamber method and infrared gas analyzer to measure the gas transfer velocity (k) and acoustic instruments to measure turbulent kinetic energy (TKE). Preliminary results found only a weak correlation between wind speed and TKE, and no significant correlation between wind speed and k. Further analysis will test for correlations between k and TKE and compare different instruments' TKE measurements, to improve models of air-sea CO2 flux.Suto, Hiroshi: The Greenhouse gas Observations of Biospheric and Local Emissi...

Radon is a useful tracer gas for estimating greenhouse gas emissions and reducing uncertainties in atmospheric transport models. However, current radon measurement techniques have inconsistencies that limit their usefulness. This study proposes a standardized protocol for radon data processing to harmonize measurements across sites and over time. Applying time response corrections to radon detector outputs from two UK sites improved correlations with methane concentrations and allowed more frequent flux estimations in atmospheric transport models. The standardized protocol has potential to better utilize radon measurements for quantifying greenhouse gas emissions.Grünwald, Thomas: Windthrow turns a former old spruce forest into a net CO2 s...

A large windthrow event in 2007 turned a former old spruce forest (DE-Hzd) into a net CO2 source for 11 years until 2017. Compared to an undisturbed old spruce forest (DE-Tha), the disturbed forest was a weaker carbon sink from 2018-2021, absorbing only 21% as much carbon. In total, the windthrow caused the disturbed forest to lose an estimated 288 tons of carbon per hectare from 2010-2021. Parallel monitoring revealed both the duration and magnitude of carbon loss following the disturbance.Davis, Kenneth: Applications of eddy covariance flux measurements in quantify...

This document summarizes research using eddy covariance flux tower measurements to quantify greenhouse gas (GHG) emissions from cities. Flux towers can directly measure CO2 and other gas fluxes continuously over urban areas. When combined with trace gas measurements and footprint modeling, flux data can be decomposed to separate biological from fossil-fuel derived CO2 fluxes. Comparisons of decomposed flux data to high-resolution urban GHG emissions inventories like Hestia show good agreement, validating the inventories. Flux towers also reveal active photosynthesis in urban turf grasses, highlighting needs to represent different urban vegetation types. Accounting for variations in rural biogenic fluxes is also important for isolating urban anthropogenic emissions.More from Integrated Carbon Observation System (ICOS) (20)

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Mapping the Growth of Supermassive Black Holes as a Function of Galaxy Stella...
The growth of supermassive black holes is strongly linked to their galaxies. It has been shown that the population
mean black hole accretion rate (BHAR) primarily correlates with the galaxy stellar mass (Må) and redshift for the
general galaxy population. This work aims to provide the best measurements of BHAR as a function of Må and
redshift over ranges of 109.5 < Må < 1012 Me and z < 4. We compile an unprecedentedly large sample with 8000
active galactic nuclei (AGNs) and 1.3 million normal galaxies from nine high-quality survey fields following a
wedding cake design. We further develop a semiparametric Bayesian method that can reasonably estimate BHAR
and the corresponding uncertainties, even for sparsely populated regions in the parameter space. BHAR is
constrained by X-ray surveys sampling the AGN accretion power and UV-to-infrared multiwavelength surveys
sampling the galaxy population. Our results can independently predict the X-ray luminosity function (XLF) from
the galaxy stellar mass function (SMF), and the prediction is consistent with the observed XLF. We also try adding
external constraints from the observed SMF and XLF. We further measure BHAR for star-forming and quiescent
galaxies and show that star-forming BHAR is generally larger than or at least comparable to the quiescent BHAR.

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.
TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptx
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.

Mechanics:- Simple and Compound Pendulum
a compound pendulum is a physical system with a more complex structure than a simple pendulum, incorporating its mass distribution and dimensions into its oscillatory motion around a fixed axis. Understanding its dynamics involves principles of rotational mechanics and the interplay between gravitational potential energy and kinetic energy. Compound pendulums are used in various scientific and engineering applications, such as seismology for measuring earthquakes, in clocks to maintain accurate timekeeping, and in mechanical systems to study oscillatory motion dynamics.

Discovery of Merging Twin Quasars at z=6.05
We report the discovery of two quasars at a redshift of z = 6.05 in the process of merging. They were
serendipitously discovered from the deep multiband imaging data collected by the Hyper Suprime-Cam (HSC)
Subaru Strategic Program survey. The quasars, HSC J121503.42−014858.7 (C1) and HSC J121503.55−014859.3
(C2), both have luminous (>1043 erg s−1
) Lyα emission with a clear broad component (full width at half
maximum >1000 km s−1
). The rest-frame ultraviolet (UV) absolute magnitudes are M1450 = − 23.106 ± 0.017
(C1) and −22.662 ± 0.024 (C2). Our crude estimates of the black hole masses provide log 8.1 0. ( ) M M BH = 3
in both sources. The two quasars are separated by 12 kpc in projected proper distance, bridged by a structure in the
rest-UV light suggesting that they are undergoing a merger. This pair is one of the most distant merging quasars
reported to date, providing crucial insight into galaxy and black hole build-up in the hierarchical structure
formation scenario. A companion paper will present the gas and dust properties captured by Atacama Large
Millimeter/submillimeter Array observations, which provide additional evidence for and detailed measurements of
the merger, and also demonstrate that the two sources are not gravitationally lensed images of a single quasar.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
