Discovery of Nine Intermediate Redshift Compact Quiescent Galaxies in the Sloan Digital Sky Survey
Ivana Damjanov, Igor Chilingarian, Ho Seong Hwang +1
We identify nine galaxies with dynamical masses of M_dyn>10^10 M_sol as photometric point sources, but with redshifts between z=0.2 and z=0.6, in the Sloan Digital Sky Survey (SDSS…
Dust Properties of Local Dust-Obscured Galaxies with the Submillimeter Array
Ho Seong Hwang, Sean M. Andrews, Margaret J. Geller
We report Submillimeter Array (SMA) observations of the 880 μm dust continuum emission for four dust-obscured galaxies (DOGs) in the local universe. Two DOGs are clearly detected w…
Measuring Galaxy Velocity Dispersions with Hectospec
Daniel Fabricant, Igor Chilingarian, Ho Seong Hwang +2
We describe a robust technique based on the ULySS IDL code for measuring velocity dispersions of galaxies observed with the MMT's fiber-fed spectrograph, Hectospec. This procedure…
The Origin of HVS17, an Unbound Main Sequence B Star at 50 kpc
Warren R. Brown, Judith G. Cohen, Margaret J. Geller +1
We analyze Keck ESI spectroscopy of HVS17, a B-type star traveling with a Galactic rest frame radial velocity of +445 km/s in the outer halo of the Milky Way. HVS17 has the project…
The Slow Flow Model of Dust Efflux in Local Star-Forming Galaxies
H. Jabran Zahid, Paul Torrey, Rolf Kudritzki +3
We develop a dust efflux model of radiation pressure acting on dust grains which successfully reproduces the relation between stellar mass, dust opacity and star formation rate obs…
Dust-Obscured Galaxies in the Local Universe
Ho Seong Hwang, Margaret J. Geller
We use Wide-field Infrared Survey Explorer (WISE), AKARI, and Galaxy Evolution Explorer (GALEX) data to select local analogs of high-redshift (z~2) dust obscured galaxies (DOGs). W…
