Current Research

Research Projects

The research program in our group addreses observational and theoretical aspects of the evolution, structure, and activities of disk galaxies across diverse environments,ranging from fields to rich clusters, and over a wide range of redshifts (z = 0 to 3), covering the last 12 billion years.

• How do galaxies grow their stars, black holes, and dark matter halos across cosmic times and vastly different environments?

• What is the role played by theoretically-predicted growth modes, such as violent mergers of galaxies and more `quiescent' modes, such as gas accretion along cosmological filaments and secular evolution?

• How does the star formation and black hole activity in the Universe evolve?

• How do galaxy clusters -- some of the largest bound structures in the Universe -- form?

Our group addresses these questions by conducting and analyzing some of the largest and deepest galaxy surveys to date. Working closely with different theorists, we also use our data to test theoretical models, improve the model baryonic physics and advance galaxy evolution paradigms. In recent years our group has been quantifying the assembly history of galaxies by measuring the merger rate, star formation rate, and black hole activity of galaxies, and also through `Structural Archaeology' -- the census of core stellar structures (classical bulges, stellar disks, and bars) at different cosmic epochs. Here is a partial list of publications. Our group's research is funded by NASA, NSF, NHARP, UT and other agencies. Please contact me for a list of current projects for graduate students.

We are part of several international science teams, which have conducted some of the largste/deepest photometric and spectroscopic surveys of galaxies, both in the nearby and distant Universe.

• GEMS (Galaxy Evolution From Morphology And SEDs): One of the first large (900 arcmin^2) contiguous field imaged with HST ACS in 2 filters (F606W) and F850LP). GEMS provides HST-based morphologies and accurate redshfits from COMBO-17 for 9,000 galaxies down to R<24 in the range z~0.2-1.2. Panchromatic coverage is provided by Spitzer, Chandra, and GALEX.

• GOODS (Great Observatories Origins Deep Survey): GOODS unites extremely deep observations from Spitzer Hubble, and Chandra, ESA's XMM-Newton.

• STAGES (Space Telescope Abell 901/902 Galaxy Evolution Survey): A multiwavelength survey to probe the physical drivers of galaxy evolution in dense environments, using HST (80 orbits; ACS F606W), Spitzer (MIPS +IRAC), GALEX (FUV,NUV), Chandra XMM-Newton, COMBO-17 spectro-photometric redshifts, and gravitational lensing mass maps.

• The HST ACS Treasury Survey of the Coma Cluster: This Treasury survey was allocated 164 HST orbits in Cycle 15 to map Coma, the richest galaxy cluster in the local Universe. Complementary Spitzer, GALEX,Chandra, and ground-based data are also available.

• The GOODS-NICMOS Survey of Massive Galaxies at z=1.7 to 3

• The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX)

• The VIRUS-P Exploration of Nearby Galaxies (VENGA): VENGA is the largest integral field spectroscopic survey of nearby spiral galaxies conducted to date. It uses 150 nights of observing time with the superb VIRUS-P Integral Field Unit (IFU) on the 2.7m telescope at McDonald Observatory.

The Hubble Ultra Deep Field (HUDF), the deepest visible-light image ever made of the Universe, (Credit: NASA, ESA, S Beckwith and HUDF home team ) shows the first galaxies to emerge from the so-called "dark ages," (the time shortly after the big bang when the first stars reheated the cold, dark universe), and chronicles a period when the universe was younger and more chaotic, with violent interactions between galaxies.
