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.
In particular, we are working on the projects outlined
below. Here is a
list of projects for students.
Impact of bars on galaxy evolution as a function of (z, environment),
with a focus on the last 8 Gyr
History and impactof interaction/mergers over last 8 Gyr
Galaxy evolution in cluster environments (Coma and Abell clusters).
What drives AGN and starburst activity in galactic nuclei?
Star formation, stellar populations, dynamics of galaxy
clusters at z=0 to 4 (pilot)
involves the analysis of extensive multi-wavelength
data, as well as a concurrent collaborative
development of the theoretical framework addressing disk evolution.
The multi-wavelength dataset for our projects
include space-based observations (e.g., from the
Hubble Space Telescope (HST),
as well as ground-based optical, NIR, and radio data.
In order to build these large datasets,
we have set up international collaborations and conducted
some of the largest and deepest observational surveys to date:
GEMS (Galaxy Evolution
from Morphology and SEDs): GEMS is the largest contiguous field
ever imaged with HST (900 arcmin2) 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 out to z~1. Panchromatic
coverage is provided by Spitzer, Chandra (Extended Chandra Deep Field South),
(Space Telescope A901/902 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 ACS Treasury survey was allocated 164 HST orbits in Cycle 15
to map Coma, the richest galaxy cluster in the local Universe.
The goal is to study the impact of environment on galaxy evolution
and provide a long-needed legacy database for comparison with
environments at different densities and redshifts.
Complementary Spitzer, GALEX,Chandra, and ground-based data are
(Hubble Ultra Deep Field): HUDF is the deepest visible-light map
ever made of the Universe, reaching more than 1.5 mag deeper than
the original Hubble Deep Field (HDF).
HUDF home team that planned and implemented the HUDF:
"Planning of the ACS Ultra Deep Field" by
Jogee, S., Ferguson, H., Stiavelli, M., Panagia, N., and Riess, A.;
"Radio and Sub-mm Considerations for the ACS Ultra Deep Field"
by Koekomoer, A., Jogee, S., Beckwith, S. V. W., and Stiavelli, M.
Scientific drivers of the UDF include probing the tail
of the reionization epoch, constraining the star formation history
of the Universe, probing the faint end of the galaxy luminosity
function, and tracking the origin, structure, and merger history
of galaxies as they evolve onto and off the Hubble sequence.
(Great Observatories Origins Deep Survey): GOODS unites
extremely deep observations from the Spitzer Space Telescope,
Hubble, and Chandra, ESA's XMM-Newton, and from the most powerful
ground-based facilities, to survey the distant universe to the
faintest flux limits across the broadest range of wavelengths.

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.
