Seminar: The Satellites and Stellar Halos of Nearby MW-mass Galaxies

When: Monday, December 9th, 2019 @ 12:30pm  

Where: PAB, 6th Floor, eScience Studio, Seminar Rm.

February 1-2, 2018.

Seminar on February 2, 2018 @ 1:00pm

I am currently an associate professor in the Astronomy Group in the Physics and Astronomy Department at Vanderbilt University. My research interests lie in the areas of large-scale structure and galaxy formation, as well as ultra-high energy cosmic rays. I completed my Ph.D. degree in Astronomy at the Ohio State University, and my A.B. degree inAstrophysical Sciences at Princeton University. Before that, I lived in Athens, Greece where I attended Athens College.

My work focuses on using large surveys to study cosmology and the evolution of galaxies. This ranges from studying the clustering of galaxies and their evolution with redshift, weak gravitational lensing of galaxies, and estimating the properties of galaxies based on their colors (aka photometric redshifts). The common theme to this work is addressing the need for massive data sets and how to work with them. One area that interests me a lot at the moment is the Large Synoptic Survey Telescope (LSST) where I lead the development of simulations of what LSST might observe. Beyond cosmology, I am also interested in how to make the technologies that companies use to search the internet useful in research and education.

Angus is a Research Fellow in the German Centre for Cosmological Lensing at the Ruhr Universität Bochum, Germany. His undertook his PhD at the University of Western Australia, where he studied the growth and evolution of baryonic mass as a member of the Galaxy and Mass Assembly (GAMA) collaboration. Following his PhD, Angus worked for the Kilo Degree Survey (KiDS) at the Argelander Institute for Astronomy at the Universität Bonn, where he began his work within weak gravitational lensing. For the last 3 years his research has focused on weak lensing survey science, and particularly on optimisation of photometric image reduction and analysis methods, systematics mitigation, and statistical analyses. Beyond weak lensing, Angus is a keen astrostatistician, a passable astronomy outreach presenter, and an enthusiastic but nonetheless mediocre golfer.

Bryce is an Asteroid Institute Associate. The main focus of his
academic studies has been the dynamical processes that affect small
body populations in the solar system and how these dynamical processes
affect the population that we see. He uses observational and numerical
modeling approaches on topics such as the evolution of asteroid
families older than two billion years, the collisional history of Main
Belt Asteroids and Near Earth Asteroids, the strength of the Yarkovsky
effect on asteroids’ orbits, asteroids’ thermal and rotational
properties and the photometric characterization of asteroids and
comets.

Bryce is a graduate student at the University of Washington and a member of the LSST Dark Energy Science Collaboration. He is interested in applying statistical techniques and machine learning to astronomical datasets and currently focusing on using such methods to improve the very different topics of photometric redshift estimation and asteroid detection.

Concurrently, AURA-LSST is excited to roll out a training video platform called Lynda.com. We were pleased to find out that University of Washington faculty and staff has access to Lynda.com. Chris will partner with the proper channels to ensure all LSST Project Members know how to access this resource so we can share videos within teams and subsystems. 

I currently work as a software and algorithm developer on the Large Synoptic Survey Telescope(LSST) as part of the Data Management, Alert Production team at UW. My main interests are in the field of cosmology specifically weak gravitational lensing and large-scale structure and using these measurements to constrain the dark sector of the Universe. I am also involved in the LSST Dark Energy Science Collaboration(DESC) developing methods to estimate galaxy redshifts from galaxy clustering statistics.

I’m interested in using time series to understand the physics of black holes and neutron stars, especially using astrostatistics, a field that makes modern statistical methods useful for astronomical data analysis. I have worked on a number of problems, including methods to help us understand variability in fast transients like magnetar bursts, and using machine learning to classify time series from black hole X-ray binaries. At DIRAC, I am hoping to combine X-ray and optical data to make our inferences about black holes better, among other things. I am also interested in how we can use machine learning and statistics to mitigate biases introduced into our data by detectors. I am lead developer for a software project called Stingray, which aims to build a standard implementation of a lot of time series methods used in astronomy. Beyond astronomy, I am interested in finding new ways to teach data science to astronomers as a co-organizer of AstroHackWeek, and I think about participant selection for scientific workshops a lot (via the software project Entrofy).

My main research interests are transiting exoplanets and young eclipsing binaries. Beyond astronomy, I am interested in the application of data science in social and economical studies. I have degrees in Physics and Economics.

My research falls in the category of astrostatistics, an interdisciplinary field of astronomy and statistics. On the astronomy side, I am interested in properties of the Milky Way Galaxy such as its mass, amount of dark matter, stellar populations, globular cluster population, and central nuclear star cluster. On the statistics side, I am interested in Bayesian hierarchical modelling, Markov chain Monte Carlo techniques, and in general, implementing and developing modern statistical methods to and for astronomical problems.

2018 recipient of the J.S.Plaskett Medal

My research interests lie in Outer Solar System object detection and planetary habitability. For the Outer Solar System, I work on the detection of moving objects below the single-frame noise floor using a gpu-accelerated “shift-and-stack” pipeline called KBMOD. More broadly, I am interested in applying advanced statistical methods to big data in order to utilize these data sets to their fullest extent. For exoplanets, I study the impact of orbital dynamics on the habitability of exoplanetary systems using a multiphysics software suite called VPLANET.

My background in experimental astrophysics has taught me that the best approach to making a major breakthrough is to develop new instruments and invent new technologies that open up possibilities for research. As a Research Scientist at the University of Washington, I have taken that philosophy to the field of radio astronomy, where I have led the development of a new end-to-end imaging algorithm for radio telescopes called Fast Holographic Deconvolution (FHD). With FHD, we have designed an imaging and deconvolution pipeline to detect the first stars and galaxies to ever form in the universe through the power spectrum of the faint diffuse radio background, but it has also opened up exciting new research opportunities to study the nearby universe, from the diffuse structure of the Milky Way to nebulae and surveys of radio galaxies.

As a PhD student at Caltech, I approached the problem of detecting the earliest stars from a different angle. While the detectable signal at radio wavelengths is emission from neutral Hydrogen outside the pockets where the first stars formed, the ultraviolet-peaked radiation from those first stars will have been redshifted to the near-infrared today and should be detectable in the power spectrum of the infrared background. To this aim, we designed and built the Cosmic Infrared Background Experiment (CIBER), a suite of two wide-field infrared cameras and two spectrometers on board a NASA sounding rocket. As the senior graduate student, I was actively involved in every aspect of the project, from initial design and fabrication, through calibration and preparation for flight, to writing the full pipeline for analysis of flight data from the imagers. During that time, I worked with deep survey data from the Hubble and Spitzer space telescopes to refine the analysis techniques, and published results that challenged the reported detection of a signal from the first stars in the infrared background from those data.

James Davenport is currently a NSF Astronomy & Astrophysics Postdoctoral Fellow, working on stellar magnetic activity using time domain surveys such as Kepler and TESS.

Ken has been recognized three times for building a “best company to work for” and in 2009 was recognized as one of Seattle’s most influential business leaders. He is on the on the board of directors of the Washington Trails Association and is an avid hiker and backpacker.

I am interested in phenomena related to Active Galactic Nuclei, including High-Energy Astrophysics, the physics of accretion disks, and black holes. My current research with Dr Ivezić involves studying the variability of  distant galaxies hosting an AGN – Quasars, using the Sloan Digital Sky Survey data, and the Catalina Real-Time Transient Survey data. Understanding the parameters of variability, and the accuracy of the Damped Random Walk model, serves as a useful tool of Physics at the accretion disk scales.

My research focuses on developing novel statistical methods for astronomy and cosmology. I am particularly interested in using Type Ia supernovae to probe the accelerated expansion of the universe that we believe is due to some form of “dark energy”.

One aspect of my research focuses on identifying Type Ia supernovae among the millions of astronomical transients that upcoming astronomical surveys such as the Large Synoptic Survey Telescope (LSST) will discover. I am currently developing the “avocado” software package that uses machine learning to classify different kinds of astronomical transients from sparsely sampled light curves with heteroskedastic noise. I am interested in understanding how biases in our observational strategies affect the performance of photometric classifiers and lead to biases in our cosmological measurements.

I am also working on developing better methods to estimate the distances to Type Ia supernovae. This involves using manifold learning techniques to parametrize the diversity of Type Ia supernovae and building non-linear models of their light curves.

Lynne Jones is the Performance Scientist for the Large Synoptic Survey Telescope (LSST) at the University of Washington and currently co-chair of the LSST Solar System Science Collaboration. She was part of the Survey/Detection panel of the  2010 NRC Commitee to Ceview Near-Earth-Object Survey and Hazard Mitigation Strategies. As part of her work with LSST, Dr Jones evaluates the scientific performance of LSST observing strategies, including the potential for studying small bodies with this next-generation telescope. She received her PhD from University of Michigan, conducting surveys to discover some of the faintest known (at the time) TransNeptunian Objects.

I worked with the LSST’s data management group on the alert production pipeline.  In graduate school I studied galaxy evolution and formation through studies of faint gas and stars in galaxy outskirts from deep optical and radio data. My dissertation focused on characterizing star formation in galaxy outer disks and the role of accretion of gas and faint companions in galaxy evolution. As a postdoc, I worked on data intensive analysis pipelines in the cloud before returning to astronomy to work on the LSST transient alert stream.

I’m interested in astronomical ‘Big Data’: developing and applying methods and algorithms that let us use large data sets to answer research questions.

Major astronomical surveys of today are routinely collecting hundreds of terabytes of images, creating databases with billions of objects and several billion measurements. Large surveys astronomers are becoming part data scientists. In my research, I go where the data takes me — I’ve worked on topics ranging from asteroids in the Solar System, Galactic structure, to the scale structure of the universe. My current focus is using survey data to understand the minor bodies of the Solar System and the structure and evolution of the Milky Way.

I currently work with the LSST Data Management team as a Project Science Analyst. My main research focus is supernovae, especially those of Type Ia.

I completed a Bachelors of Science with Honours and a Specialization in Astrophysics at Queen’s University in Kingston ON Canada, with a Junior year abroad at the University of Glasgow in Scotland, and a Doctorate of Philosophy in Astrophysics at the University of Victoria in Victoria BC Canada. After a joint postdoctoral fellowship at UC Santa Barbara and the Las Cumbres Observatory Global Telescope Network (www.LCOGT.net) I moved to a senior postdoctoral fellowship at UC Berkeley and then joined the the Large Synoptic Survey Telescope team at the University of Washington as a research staff scientist in 2016.

I am a researcher and developer on the LSST Data Management team.

I write software that will process a deluge of images in real time when LSST begins collecting frames for a decade-long movie of the southern sky. My research includes observing weird binary stars and using them to better understand how all stars work. I hold degree in physics and astronomy from New Mexico State University, San Diego State University, and Harvey Mudd College.

Beyond astronomy I enjoy playing viola, advocating for more equity and less light pollution, and figuring out how to be a parent.

June 27-29, 2018.

I work on Galactic Archaeology, which is the study of the structure and evolution of the Milky Way. I did my PhD at New Mexico State University working with Jon Holtzman and Jo Bovy with the APOGEE survey, which is an SDSS3 and SDSS4 spectroscopic survey of several hundred thousand red giants across the Milky Way. I spent two years working in Nice at the Observatoire de la Cote d’Azur with the Gaia-ESO and AMBRE projects, which have spectroscopic observations of tens of thousands of stars throughout the Galaxy. 

Currently, I am an ASTRO 3D fellow working at the University of Sydney with the GALAH Survey. GALAH  is a large-scale spectroscopic survey of 500,000 stars throughout the Milky Way, and aims to measure chemical abundances for 30 different elements to map and chemically tag the stellar populations of the Galaxy. In my talk, “Chemical Cartography of the Milky Way”, I will discuss the chemodynamic properties of different stellar populations throughout the disk and how they vary with location.

I attached a figure of some preliminary results from the GALAH survey, showing how the chemical structure of the disk varies from the inner Galaxy to the edge of the disk.

Seminar Talk on February 12, 2018 @12:30pm

November 29-30, 2018.

I’m interested in galaxies: how did they form and end up looking the way they do today? There are lots of different ways to attack this problem: my interest is in observational studies of both nearby galaxies and their star clusters and also distant, high-redshift galaxies. I’ve used quite a few different telescopes and instruments, with a lot of emphasis on infrared observations with the Spitzer Space Telescope. 

Astronomical observations can probe physical phenomena at length and time scales, possibly in exotic environments largely inaccessible to terrestrial laboratories. While this underlies some of the successes of cosmological surveys over the past decades in discovering new physics, extracting such information is challenging because the data are typically noisy, and includes effects due to different processes (astrophysical, atmospheric and instrumental) tangled together in complex ways. I work in the area of extracting (inference along with classification) of such information from large surveys and am particularly interested in cosmology at late times, mostly through transients like supernovae and large scale structure. I am currently involved in LSST and ZTF.

Theodore A. Wagner, M.D. is a clinical professor of orthopedics and sports medicine, specializing in spine surgery. Dr. Wagner is also an adjunct professor in the Department of Neurological Surgery at the University of Washington’s School of Medicine in Seattle.

Dr. Wagner earned a bachelor’s degree from Trinity College in Connecticut and his medical degree from Temple Medical School in Philadelphia. After an internship in surgery in Montreal, he came to the UW for a residency in orthopedic surgery. He is board certified in orthopedic surgery.

Dr. Wagner’s clinical interests include biological spine disk regeneration, scoliosis, spine traumas and spine degeneration.

Dr. Wagner believes spinal surgery is a very definitive type of surgery with somewhat predictive complications of occurrences. He believes in teaching his patients what he knows and what he doesn’t know about their future before he does the index surgery.
