This document discusses building density maps of the local universe using red clump (RC) stars and galaxy distributions from the Dark Energy Survey (DES). It selects RC stars from the CasJobs database and projects their maps using different projections. It subtracts foreground stars using the Galaxia and Trilegal models to map the halo RC star distributions in the north and south. It also builds maps of galaxy distributions at z~1/3 from the DES PhotoZ catalog. The document reviews literature on searches for evidence of a supervoid near the Planck Cold Spot region using different galaxy surveys that have had limited sky coverage to make definitive conclusions.

The document summarizes a study that measured the mass of the exoplanet Kepler-78b using radial velocity measurements from the HARPS-N spectrograph. The study found Kepler-78b has a mass of 1.86 Earth masses and a density of 5.57 grams per cubic centimeter, similar to Earth. This makes Kepler-78b the smallest exoplanet with accurately measured mass and radius, and the most similar to Earth in terms of its mass, radius, and density.

The Homogenization and Reporting of Groundbased Atmospheric Datasets for the ...The HDF-EOS Tools and Information Center
The geophysical validation of satellite borne atmospheric chemistry instruments requires a large number of independent observations by a variety of in-situ, remote-sensing and satellite instruments. In the case of the Aura and Envisat missions more than 300 instruments have been formally included in the validation efforts.
In order to extract maximum information from the "ground-truth" measurements, these independent validation datasets must be readily accessible to all investigators in an simple format with standard metadata, variable naming and data structures.
Beginning in 2000, NASA and ESA have been collaborating under the auspices of the CEOS Working Group Calibration/Validation (WGCV) Atmospheric Chemistry Sub Group (ACSG) on the file format definition, metadata formulations, and variable definitions for validation datasets.
This standard, known as the AVDC/Envisat HDF format, is the basis of the Aura Validation Data Center (AVDC) and the Envisat Cal/ Val Data Center implementations. Recently, the AVDC/Envisat HDF formulation has been accepted as the new reporting standard of the Network for the Detection of Atmospheric Composition Change (NDACC), an international network of high quality remote sensing stations, and for the next ESA GMES Earth Observing missions. The concept behind the AVDC/Envisat HDF reporting standard, its implementation and future applications will to be presented in detail. Oil and Gas Imaging, pumpsandpipesmdhc
Seismic imaging is used in oil and gas exploration to determine reservoir geometry and properties by analyzing acoustic echo reflections from subsurface layers. It is a two-step process that first uses varying source-receiver separations and tomography to determine subsurface velocities, and then backpropagates measured sound waves to form images. Advancements include more accurate imaging algorithms, improved velocity modeling tools, and increased data acquisition apertures, but challenges remain such as illumination limitations, complex velocity models, imaging steep dips and structures, and issues of resolution and noise.
OWL-Time and enhancements
This document discusses potential enhancements to OWL-Time. It notes that OWL-Time currently uses Allen's temporal model and represents time positions using the Gregorian calendar only. It proposes a generalization that would allow OWL-Time to indicate and use other temporal reference systems like geological time scales or non-Gregorian calendars. This would support more temporal representations like coordinates on a timeline or ordinal named intervals, while retaining interval logic and avoiding changes to existing OWL-Time users and data.
Ronan Kerr: Exploring the Debris Disk Around Beta Pictoris
The document summarizes research analyzing nitrogen abundance in the debris disk around Beta Pictoris. It finds that modeling the data as having three components - interstellar medium, circumstellar disk, and wider component possibly from exocomets - provides the best fit. This points to preferential production rather than depletion as the cause of carbon and oxygen excess in the system. Future work could examine other molecular abundances and test how well the proposed dual-origin solution explains other elements.

This study aims to:
1) Characterize the properties and abundance of blocks in lunar impact craters using radar and imagery data.
2) Determine how block field properties correlate with radar measurements and differ between crater types.
3) Provide insights into the formation and evolution of block fields to help distinguish between blocky ejecta and polar ice deposits.
Spacecraft Formation Flying Navigation via a Novel Wireless Final
The document discusses spacecraft formation flying and orbit estimation techniques. Key points include:
- Wireless localization positioning systems (WLPS) can be used to estimate the absolute positions of spacecraft in a formation by measuring their relative positions and angles.
- Implementing a differential geometric filter (DGF) for orbit estimation improves stability and convergence compared to an extended Kalman filter by avoiding linearization.
- A constrained Kalman filter can be used to estimate when spacecraft reach apogee and perigee in their elliptical orbits by applying constraints at points where the first derivative is zero.

WE2.L09 - DESDYNI LIDAR FOR SOLID EARTH APPLICATIONS
1) Simulations show DESDynI-Lidar could provide topography profiles from Alaska advancing studies of seismic and tectonic processes. Lidar could measure coseismic uplift from past earthquakes with 25m profiles and global georeferenced elevations.
2) Fusion of Lidar elevations into SAR processing could help by providing accurate ground control points, improving baseline refinement and DEM accuracy and density particularly at high latitudes.
3) Initial tests reconstructing Lidar waveforms show potential to study variable terrain and vegetation structure, and measure coseismic offsets over 1m with a single acquisition to guide further study.

Talk at MUSE Science Meeting @ Leibniz-Institut für Astrophysik in Potsdam (AIP) presenting a recent Paper by P. Laursen et al. http://dx.doi.org/10.1088/0004-637X/766/2/124Spatialy resolved emission_of_a_high_redshift_dla_galaxy_with_keck
This document presents observations from the Keck/OSIRIS integral field unit of a galaxy detected in absorption as a damped Lyman-alpha system (DLA) along the line of sight to a background quasar. Laser guide star adaptive optics were used to achieve high spatial resolution, allowing the detection and mapping of emission from the DLA galaxy free from contamination by the quasar. Emission from H-alpha and [O III] is detected and used to measure a star formation rate, dynamical mass, velocity field, and evidence of possible metallicity gradients in the galaxy. While some irregular kinematic features are seen, no clear rotational signature is observed that would support an edge-on disk interpretation of the galaxy's structure

The big data Universe. Literally.
The document discusses the challenges of big data in astronomy. It describes several upcoming and current astronomical surveys that will produce enormous amounts of data, such as Euclid which will collect 15 terabytes per day starting in 2022. Dealing with such large datasets requires new techniques for storage, processing, analyzing, classifying, compressing and visualizing the data. Machine learning and citizen science are helping to process the data more efficiently. Future surveys like the Square Kilometer Array telescope will pose even greater challenges by producing data at terabytes per second.
Applications Of Computer Science in Astronomy
In the document, the following points are made about the use of computers in astronomy:
1) Automated observatories like the Hubble Space Telescope use algorithms to select targets and schedule observations in order to efficiently observe many astronomical objects.
2) Citizen science projects like Zooniverse classify large amounts of astronomical data by crowdsourcing classifications to volunteers in order to help researchers study more data than possible otherwise.
3) Simulations of astronomical phenomena that are difficult to observe like stellar collisions are used to study and confirm hypotheses, with simulations becoming more accurate as computational capabilities increase.

This document summarizes a search for Centauro events at the PHENIX experiment at RHIC. It discusses the history and previous searches for Centauro events. The analysis uses PHENIX data from Au+Au collisions at √sNN = 200 GeV to look for anomalous domains with large deviations between the number of charged tracks and photon-like clusters in η-φ phase space bins. A multi-resolution analysis technique is used to identify potential Centauro-like domains and estimate their size and position on an event-by-event basis. Preliminary results are shown for the maximum deviation between charged and neutral particles across bins and in different centrality bins.
Manuscript7
This document analyzes trajectories to reach the heliopause and exit the solar system using nuclear thermal propulsion (NTP) and Oberth maneuvers. It finds that NTP, which can provide much higher specific impulse than chemical propulsion, enables significantly faster trajectories when combined with Oberth maneuvers where the spacecraft fires its engines near the closest approach to the Sun. The document models trajectories from various launch vehicles that take the spacecraft close to the Sun, where it executes a large velocity change to enter an hyperbolic orbit leaving the solar system. It finds that lower perihelion distances and higher Oberth burns result in higher exit velocities from the solar system.

The Square Kilometre Array Science Cases (CosmoAndes 2018)
The Square Kilometre Array (SKA), even in its first phase (SKA Phase 1, or SKA1) will be the largest ground-based astronomical facility ever built, with unprecedented sensitivity in the frequency ranges for local to highly redshifted HI, and future expansion up to 25 GHz. The range of science cases that the SKA telescopes will cater for will also be the largest of any research facility, from the Epoch of Reionization (EoR) and the Cosmic Down (CD), to tests of Einstein’s General Relativity, to finding all detectable pulsars in the Milky Way, and helping with the Cradle of Life case for Astrobiology. In this talk we will go through the different science cases, with emphasis in those with the most cosmological significance, such as EoR, CD, and probing General Relativity.

The document discusses developments in gas, power, and carbon markets over the past week. UK gas and power prices rose due to lower expected LNG deliveries and nuclear availability in France. Coal prices reached their highest level since 2015 due to China's production cuts. Carbon prices followed gains in coal and oil. The outlook predicts gas and power prices remaining bullish due to tight supply and increasing demand as temperatures fall. An OECD report calls for higher global carbon prices to drive the emissions reductions needed to meet climate targets.

Collection of data
This document discusses primary and secondary data sources for collecting information. Primary data is originally collected by the researcher, such as through direct observation, interviews, questionnaires, or surveys. Secondary data has already been collected by other agencies and researchers, such as published government reports, research papers, or unpublished records. When deciding on a data collection method, researchers must consider factors like the study objectives, resources, time availability, and required accuracy. Both primary and secondary data have advantages and limitations that researchers should be aware of to appropriately evaluate and utilize the data.

Astrophysical constraints on dark matter
This document discusses the nature of dark matter, whether it is warm or cold. It provides evidence from simulations and observations that both support and cast doubt on the standard cold dark matter (CDM) model. On small scales, CDM simulations predict more substructure than observed, and cuspy dark matter density profiles rather than cored profiles as suggested by some observations of dwarf galaxies. Warm dark matter is proposed as an alternative to address these issues, but current constraints from Lyman-alpha forests limit the mass of warm dark matter particles. Future weak lensing surveys like Euclid may help constrain the nature of dark matter.
FDL 2017 3D Shape Modeling
The document discusses improving the process of generating 3D shape models of asteroids from radar observations. It proposes several solutions: a) Pre-processing radar data faster, b) Determining asteroid spin axes faster using Bayesian optimization, c) Improving the generation of training data using non-convex synthetic shapes, and d) Advancing the neural network approach using techniques like variational autoencoders to represent asteroids in a compact latent space. The overall aim is to streamline the modeling pipeline to analyze radar observations of near-Earth asteroids faster than they are acquired.
DISSERTATIONJOAKIM676951
This document is a dissertation by Joakim Carlsen submitted in 2014/2015 for a Bsc(Honours) in Applied Physics. It investigates detecting massive galaxies at high redshift (z > 4) using photometric data from the Dark Energy Survey (DES). The dissertation aims to identify massive galaxy candidates at z > 4 based on their colors and fit their spectral energy distributions using photometric redshift modeling software. Several high redshift massive galaxy candidates were identified and their properties were analyzed, with the most promising candidates to be proposed for follow-up spectroscopy to confirm their redshifts.
KNAC_MCrnogorcevic_HDKoch
This document summarizes a study that used new selection criteria to identify obscured quasars in the Stripe 82 region. The researchers utilized infrared data from WISE to select objects with color ratios characteristic of quasars that did not already have spectra in the Sloan Digital Sky Survey (SDSS), indicating they were likely obscured. They obtained optical and infrared spectra for 8 candidates using Keck and NASA's SpeX telescope. After reducing the data, they calculated redshifts and fit Gaussian functions to emission peaks to generate spectra. BPT diagrams showed that 6 of the 8 sources were quasars based on the new selection techniques.
Bruce Damer's presentation on How to Mine the Moon (Nov 2006)
The document discusses plans for robotic exploration of the moon to study lunar regolith and search for water ice in permanently shadowed craters near the south pole. It describes the goals of exploring the surface and subsurface of a crater to examine volatile deposits and collect samples from varied locations. It also mentions using CAD/CAM simulations to design a prototype bucket wheel excavator and compares Dawes Crater to Shackleton Crater as potential analog sites for the robotic exploration mission.
Low surface brightness_imaging_of_the_magellanic_system_imprints_of_tidal_int...
We present deep optical images of the Large and Small Magellanic Clouds (LMC and SMC) using
a low cost telephoto lens with a wide field of view to explore stellar substructure in the outskirts
of the stellar disk of the LMC (r < 10 degrees from the center). These data have higher resolution
than existing star count maps, and highlight the existence of stellar arcs and multiple spiral arms in
the northern periphery, with no comparable counterparts in the South. We compare these data to
detailed simulations of the LMC disk outskirts, following interactions with its low mass companion,
the SMC. We consider interaction in isolation and with the inclusion of the Milky Way tidal field.
The simulations are used to assess the origin of the northern structures, including also the low density
stellar arc recently identified in the DES data by Mackey et al. (2015) at ∼ 15 degrees. We conclude
that repeated close interactions with the SMC are primarily responsible for the asymmetric stellar
structures seen in the periphery of the LMC. The orientation and density of these arcs can be used to
constrain the LMC’s interaction history with and impact parameter of the SMC. More generally, we
find that such asymmetric structures should be ubiquitous about pairs of dwarfs and can persist for
1-2 Gyr even after the secondary merges entirely with the primary. As such, the lack of a companion
around a Magellanic Irregular does not disprove the hypothesis that their asymmetric structures are
driven by dwarf-dwarf interactions.
Science with small telescopes - exoplanets
The search for extrasolar planets has become one of the most attractive problems in modern astrophysics. The biggest observatories in the world are involved in this task as well as little amateur instruments. There is also a huge variety of astronomical methods used for their investigation. Here I present the projects for searching for exoplanets by transit method and our observations of the planet WASP-2b. We observed a transit on 3/4 August 2008 with a 354 mm Schmidt-Cassegrain Celestron telescope and CCD SBIG STL 11000M camera. By precise photometry made using MaximDL software we obtained the light curve of the star system. Decrease of brightness by 0.02m is detected. Analyzing our data we estimate the radius of the planet and inclination of its orbit. Our results are in good correlation with the published information in literature.

AAS_Beth_poster
This study analyzed the photometric profiles of 10 nearby early-type galaxies using data from the Sloan Digital Sky Survey to compare with previous studies. Ellipticity and position angle profiles were created for each galaxy in MATLAB. The profiles showed overall trends of increasing ellipticity with position angles hovering around zero, with some exceptions for galaxies like NGC 4382 that are known merger remnants. Further analysis will attempt to improve consistency with previous studies by masking nearby objects and will extend the methods to all 25 galaxies in the SLUGGS survey.

To themoon
Robots could be used to further explore and scout the moon in preparation for future human missions. Past lunar rover missions, such as Lunokhod 2 which traveled over 24 miles on the moon's surface over 6 months, demonstrated that rovers can perform useful functions. Current rover concepts, like Scarab, are designed with capabilities like drilling and navigating steep terrain. Recent NASA lunar precursor missions, including the Lunar Reconnaissance Orbiter and LCROSS impactor, gathered extensive data on potential landing sites and the presence of resources like water ice, informing where future rover missions could explore.
Line Spectra and Doppler Shifts One way that astronomers detect exopla.pdf
Line Spectra and Doppler Shifts One way that astronomers detect exoplanets is by observing the
wobble of their host stars via doppler shifts. This is known as the radial velocity technique. The
simulated spectra provided on the last page show the position of a 1-solar-mass star's hydrogen-
alpha absorption line over time. In the laboratory (at rest), this absorption line occurs 656
nanometers. 4) Calculate the star's radial velocity from each spectrum using the doppler
equation, and fill in the table provided. Then, sketch the associated graph. 5) Estimate the period
of this system's orbit based on your graph. (Measure the time between two peaks or two troughs.)
Convert your answer to years. 6) Calculate the semi-major axis of this exoplanet's orbit using
Kepler's law. How does this compare to the orbit of Mercury? (This exoplanet is known as a "hot
Jupiter." Does the nickname make sense?) Data.

This document proposes the New Worlds Imager, an alternative to the Terrestrial Planet Finder that could directly image exoplanets using a starshade to block starlight. The starshade employs a novel apodization function that suppresses diffraction to high precision, allowing Earth-sized planets to be detected with small telescopes. A two-tiered approach is proposed, with New Worlds Observer performing photometry and spectroscopy using existing technology, and New Worlds Imager seeking to directly image planets using a more advanced 5-spacecraft interferometer requiring development over the next 10-15 years.
Producing science with_ptf
The Palomar Transient Factory (PTF) uses the 48-inch Samuel Oschin Telescope at Palomar Observatory to discover transients and variables in the sky. It aims to study extragalactic and galactic phenomena such as supernovae, tidal disruption events, cataclysmic variables, and structures in the Milky Way. The PTF uses a wide-field imager to discover objects and then coordinates follow-up with spectrographs on the Palomar 200-inch and other telescopes. It has discovered over 2,000 supernovae and published numerous science papers. The Zwicky Transient Facility (ZTF) will improve on the PTF with a larger field of view
Peekaboo: the extremely metal poor dwarf galaxy HIPASS J1131–31
The dwarf irregular galaxy HIPASS J1131–31 was discovered as a source of HI emission
at low redshift in such close proximity of a bright star that we call it Peekaboo. The galaxy
resolves into stars in images with Hubble Space Telescope, leading to a distance estimate
of 6.8 ± 0.7 Mpc. Spectral optical observations with the Southern African Large Telescope
reveal HIPASS J1131–31 to be one of the most extremely metal-poor galaxies known with
the gas-phase oxygen abundance 12+log(O/H) = 6.99±0.16 dex via the direct [OIII] 4363 line
method and 6.87±0.07 dex from the two strong line empirical methods. The red giant branch
of the system is tenuous compared with the prominence of the features of young populations in
the color-magnitude diagram, inviting speculation that star formation in the galaxy only began
in the last few Gyr
Xray discovery of_a_dwarf_galaxy_galaxy_collision
A dwarf galaxy is colliding with the large spiral galaxy NGC 1232, as revealed by X-ray observations from Chandra. The collision is creating a large region (7.25 kpc in diameter) of shocked, hot gas with a temperature of around 5.8 million kelvin. The X-ray luminosity of this collisional aftermath is estimated to be 3.7x10^38 ergs/s. Based on the size and temperature of the X-ray emitting region, the collision likely involves a dwarf galaxy and represents a massive energy input into NGC 1232, far exceeding a typical supernova. Such collisions detected solely in X-rays may provide insights into the role of dwarf galaxy interactions in the evolution of
Moon Through New Eyes of Korean Mission: KPLO/PolCam
1) The document discusses Korea's lunar exploration program, which includes the Korea Pathfinder Lunar Orbiter (KPLO) mission scheduled to launch in late 2020.
2) KPLO will carry several science payloads including PolCam, a polarimetric camera built by KASI that will create the first polarization map of the lunar surface.
3) Analyzing the polarization data from PolCam can provide information about lunar regolith properties like particle size and maturity, as well as titanium distribution, to advance understanding of space weathering processes.
Ultimate astronomicalimaging
This document discusses the potential for x-ray interferometry and the Maxim Pathfinder mission concept. It describes how an x-ray interferometer could achieve much higher resolution than current x-ray telescopes by using multiple collector spacecraft separated by long distances. The Maxim Pathfinder would demonstrate 100 microarcsecond resolution using two spacecraft separated by 450 km. System modeling tools would be crucial for development and optimization of the interferometer design.

This document summarizes a study that mapped the three-dimensional density distribution of the Galactic bulge using red clump giant stars identified in the VISTA Variables in the Via Lactea (VVV) survey. The authors constructed extinction maps and used the red clump stars to estimate line-of-sight density distributions by deconvolving the intrinsic luminosity function. Assuming an 8-fold mirror symmetry, they used the line-of-sight densities to construct a 3D density map covering the inner (2.2 × 1.4 × 1.1)kpc of the bulge/bar. The resulting density distribution shows a highly elongated bar with an exponential fall off and axis ratios characteristic of a strongly boxy/pe
Lecture 18.ppt
This document summarizes key concepts about black holes from a lecture. It discusses time dilation, length contraction, and redshift near black holes based on Schwarzschild's solution. It also describes features of rotating black holes based on the Kerr solution, including frame dragging and ergospheres. Finally, it discusses observational evidence for stellar-mass, supermassive, and intermediate-mass black holes, and how black holes power active galactic nuclei through accretion.
