Agol, Eric
Interests: Eric Agol studies extrasolar planets, black holes, and gravitational lenses. He uses analytic computations, numerical simulations, and observations to discover and characterize these objects. With collaborators, he was the first to propose that radio observations could be used to image the shadow of the event horizon of a black hole; he was the first to create an infrared longitudinal map of an extrasolar planet; he has written computer code used to characterize over 50 transiting extrasolar planets; and he has proposed a novel technique for finding planets as small in mass as the Earth, and used it to demonstrate that Earth-mass planets could be detected in resonance with transiting planets, were they present.

Becker, Andrew
Interests: My research interests in the past have focused on detecting and following-up unusual microlensing events in real-time (with MACHO, GMAN, and MPS). However, my pursuits have since broadened to the generalized problem of detecting and classifying astronomical variability regardless of type (with DLS, SDSS, and LSST). In particular, if one wants to recognize rare classes of transient events, the background of more prosaic astronomical variability must first be recognized and removed. Modern surveys that simultaneously survey faint, fast, and wide are now at a threshold where we expect these new sorts of discoveries. Accomplishing this will require advances in the integration of computing and information management necessary to extract and model astronomical variability information in real-time. Recent science pursuits include: mining survey data for distant Trans-Neptunian Objects, phasing large time-series of 2MASS data for periodic variability, pursuing a novel method to estimate Supernova Type Ia distances and constrain cosmology, undertaking a Principal Component Analysis of M-dwarf spectra, and writing reams of software for the Large Synoptic Survey Telescope.

Böhm, Karl-Heinz
Interests: He taught earlier (until 1999) mostly stellar and solar physics. Research interests: Outflows ("Herbig-Haro jets", "disk winds" from recently formed stars, specifically T Tauri stars). The research concentrates mostly on the interpretation of (highly) spatially resolved spectra of outflows (optical, UV, and some near IR) and the interpretation of their background physics. - He is also interested in the hydrodynamic (and magneto-hydrodynamic) generation of outflows (jets) from young stars. Earlier interests include radiative equilibrium in stellar atmospheres and atmospheric and internal structures of white dwarfs.

Connolly, Andy
Interests: 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. As part of this, a couple of years ago I was on sabbatical at Google where I created "Google Sky"; an extension to Google Earth that streams many Terabytes of astronomical images and provides an easy way to zoom and pan throughout the universe.

Interests: My main research interest is how to characterize exoplanets once they are discovered. My thesis work described how to create thermal maps and albedo maps of exoplanets based on how their brightness changes over an orbit or rotation. I have made maps of exoplanets using data from Spitzer and maps of Earth with data from the EPOXI mission. I also dabble in survey astronomy (namely determining the environment of galaxies) using SDSS and the Millenium Simulation.

Huang, Wenjin
Interests: Major line features in stellar spectra, for ex., the HI Balmer and Paschen series, are very helpful for us to understand stellar surface environment astrophysically. However, current line synthesis theories (LTE/NLTE) are still far from successfully simulating the formation of these HI lines in atmosphere of supergiants. Working closely with Dr. Wallerstein G., we start a project to investigate on what is the major barrier that causes the failure of HI line synthesis for supergiants.
Comparing with late GKM type stars, massive OBA stars rotate much faster during their main sequence stage. Theoretical studies suggest that high rotation velocity make the surface condition and the internal structure of these massive stars very different from that of slowly rotating stars. My primary research interest is in studying stellar rotation of massive stars at the observational side. Obtaining reliable statistical data of stellar rotation is the only way to verify/put constraints on the stellar rotation theories, and to help us to understand the key role of angular momentum playing during the entire life of massive stars. This kind of studies may also shed light on other long-standing puzzles in this area, such as the origin of Be stars and chemical peculiar stars, etc.

King, Ivan R.
Interests: Research centers on the structure and population content of globular clusters. Current work is based on observations made with the Hubble Space Telescope. Much of present efforts are in high-precision astrometry with HST, which allows the study of internal motions of stars in the clusters. This will lead to a better understanding of the dynamics of the clusters, and eventually to a marked improvement in the scales of their distances and ages. At the same time, proper-motion separation of cluster stars from field stars allows study of cluster stars down to the hydrogen-burning limit. Other efforts go into dynamical modeling of globular clusters. Peripheral interests in the structure of the Milky Way and of other galaxies.

Krughoff, Simon
Interests: Using the SDSS spectroscopic sample we are looking for transient signals using the PCA decomposition of the galaxy spectra. Specifically we are finding type Ia supernovae superimposed on the host galaxy spectrum. Using this sample of SNe we have been able to calculate the nearby type Ia supernova rate. Research facilitation
One of my main interests is facilitating research in the era of big data in astronomy. As datasets (both catalog and imagery) grow to sizes too large to harbor effectively on a single desktop machine, the astronomical community must rethink how things get done. In an effort to probe new ways to do things, I've been involved in several projects to put exploratory science on the web (where it belongs).
Web Enabled Source Identification with X-Matching is a proof of concept project to demonstrate how several NVO produced protocols and tools can be linked together to provide increased functionality. In the case of WESIX, the source identification tool SExtractor and the cross matching tool OpenSkyQuery are glued together using some Java and JSP to provide a tool for identifying sources and getting their counterparts from another catalog in one (relatively) simple step.
Another aspect of research facilitation is the simplification and distribution of data access portals. The Pitt/CMU Value Added Catalog (VAC) is an attempt to make the SDSS spectroscopic data products more accessible. It is also an intended to simplify aggregation of value added products by providing an upload page where new calculated quantities can be matched to the catalog.

Mukadam, Anjum
Interests: White dwarf stars are the stellar remains of 98-99% of stars in the sky. Anjum chose to work on pulsating white dwarfs in particular because pulsations allow us to probe deep in the interior of the star, not otherwise accessible for a systematic study. A unique model fit to the observed periods of the variable white dwarf can reveal information about the stellar mass, core composition, age, rotation rate, magnetic field strength, and distance. In collaboration with Dr. Paula Szkody, Anjum also works on accreting white dwarfs that show pulsations. These systems are of great interest to both the pulsating white dwarf community and the cataclysmic variable community.

Silvestri, Nicole M.
Interests: While at Florida Tech I worked primarily on white dwarf stars, specifically those in wide binary systems with M dwarf companions. My dissertation research focused on the determination of a chromospheric activity-age relation from the activity of the M dwarf and the age of the white dwarf in these systems (publication by summer, 2003!). Now that I am here at UW, my research interests have shifted slightly to the investigation of close white dwarf-M dwarf binary systems. We plan to observe enough of these systems to see what they can tell us about the activity of M dwarf stars in close binary systems and what influence this magnetic activity might have on cataclysmic variable systems. I am also interested in studying the variability, ages, and other observable properties of white dwarf and low mass stars and I am currently working on several white dwarf and M dwarf projects through collaborative efforts with the SDSS and Florida Tech.

Szkody, Paula
Interests: Professor Szkody uses a multiwavelength approach to study close binary stars with active mass transfer (Cataclysmic Variables). Her current research involves ultraviolet observations with the Hubble Space Telescope and the GALEX and FUSE satellites, X-ray observations with Chandra and SMM, infrared observations with Spitzer as well as APO and ground-based optical facilities around the world. With colleagues participating in the Sloan Digital Sky Survey, she is currently finding the faintest, lowest mass transfer CVs. These observations have led to insights into the nature of mass transfer and accretion onto magnetic and non-magnetic white dwarfs, the structure of accretion onto magnetic and non-magnetic white dwarfs, the structure of accretion disks and their X-ray-emitting boundary layers, stellar coronae, and the effects of irradiation on the upper atmospheres of late-type secondary stars. The results are elucidating the long-term evolution leading to the formation of these ultrashort period binaries.

Wallerstein, George
Interests: Professor Wallerstein's research is oriented around the chemical composition of stellar atmospheres. These are important clues to the composition to the origin of the star and its evolution. Stars reflect the environments of their formation by the composition of the gasses in their atmospheres. For example, stars formed 10-15 billion years ago in globular clusters show that these clusters ceased to produce the heavy elements seen in the Sun after only 1 percent of the solar level of heavies were produced. Other stellar atmospheres show a composition which was changed by nuclear reactions in their interiors. Prof. Wallerstein works closely with his students in observations at the telescope and the analysis of these data using computer models of stellar atmospheres. They interpret their data in terms of theories of stellar structure and core nuclear burning. Prof. Wallerstein also studies the structure of the interstellar medium through emission and absorption lines.

Interests: Ben Williams works on galaxy evolution, focusing on explaining the observed properties of nearby galaxies. Using Hubble Space Telescope and the Chandra X-ray Observatory, the stellar populations and X-ray source populations of nearby galaxies can be studied in great detail. These population contain the information necessary to reconstruct the evolutionary history of galaxies. Comparing our observations to theoretical models and high-redshift observations tests and improves current theories and simulations.
