Faculty and Postdoctoral Researchers:
Andrew Wilson
The early research interests of Andrew Wilson were supernova remnants and
cosmic ray propagation. However, most of his research has been concerned
with active galaxies, black holes and extragalactic astronomy. The primary
goal is to understand active galactic nuclei, especially the production of
jets and mass outflows from these objects. Wilson is a member of the
Chandra Science Working Group and has, since 2000, been working on
Chandra observations of nearby Seyfert and radio galaxies.
Stuart Vogel
Stuart Vogel is a radio astronomer working on star formation and the
interstellar medium in the Milky Way and nearby galaxies.
He is the Maryland director for the Berkeley-Illinois-Maryland
array of millimeter-wave telescopes. He also has
a Fabry-Perot spectrometer for studies of extended optical
emission line objects.
My optical interests include galactic nebulae,
gas flows in galaxies, detection of ionized gas above
and beyond the HI disks of galaxies, and measurement
of the metagalactic ionizing flux.
Sylvain Veilleux
The research interests of Sylvain Veilleux center on understanding the
nature, origin and impact of starburst/black-hole driven activity in galaxies,
and on the formation and evolution of galaxies. Most of my work involves the
analysis of ground-based observations at optical and infrared wavelengths
supplemented with data obtained with astronomical satellites. I have
also been involved in trying to put stronger constraints on the metagalactic
ionizing flux and the gaseous extent of galaxies. Veilleux is supervising
the research of graduate students Rachel Gibbons, Scott Miller, David Rupke,
and Lisa Mazzuca.
Stacy McGaugh
Stacy McGaugh studies galaxies, cosmology, and the mass discrepancy problem.
His primary interest has been in low surface brightness galaxies, a
recently recognized class of
diffuse objects which tell us a great deal about galaxy formation
and evolution in general. McGaugh is supervising the research of grad
students Jim Marshall, who is working on a large survey for very low
surface brightness galaxies, Ji Hoon Kim, who is studying the evolution
of such objects, and Rachel Kuzio, who is working to measure helium abundances
in near-primordial HII regions in LSB galaxies.
Chris Reynolds
Chris Reynolds has performed
substantial observational investigations into active galactic nuclei, with a
particular emphasis on the diagnostic properties of the
Fe K alpha line profile. He has also done a great deal of
theoretical research focused on magnetohydrodynamics near
the inner edges of accretion disks around black holes.
He has shown that significant energy may be extracted from inside
the innermost stable circular orbit around black holes, either
from the rotation of the black holes themselves or from
MHD interactions. The initial work has used a pseudo-Newtonian
potential formalism with simple equations of state, but Reynolds
intends to expand this investigation to fully relativistic disks with
more realistic equations of state.
DongChan Kim
DongChan Kim's primary research interests are imaging and spectroscopic
studies of the luminous infrared galaxies (LIGs), ultraluminous infrared
galaxies (ULIGs), and QSOs. Currently, he is involved in data reduction
and analysis of the HST/NICMOS imaging and SPITZER IRS spectra of the
ULIGs and QSOs. The main goal of these studies is try to understand
evolutionary connection between ULIGs and QSOs. He is also interested
in developing database archive systems and CGI programing.
Benjamin Weiner
Benjamin Weiner's research interests include the internal dynamics
of galaxies, the formation of galaxy disks, and the evolution of
galaxy luminosities, colors, and star formation histories. An
ongoing project is to measure evolution in the Tully-Fisher relation
between galaxy luminosity and dynamical mass, and to use the
evolution to constrain models of galaxy formation. He is currently
working on the Maryland-Magellan Tunable Filter instrument being
developted for the 6.5 meter Magellan telescope in Chile.
David Rupke
The research interests of David Rupke are centered around galaxy evolution.
He studies massive galaxies undergoing intense star formation, galaxies
hosting supermassive black holes, and galaxies that are undergoing a merger
with another galaxy. Particular emphases have been on "winds" of gas from
galaxies; ionized gas on the outskirts of starburst and active galaxies
using sensitive interference filters; and, most recently, infrared
spectroscopy of galaxies from space-based instruments.
