To the Edge of M87 and Beyond: Spectroscopy of Intracluster Globular Clusters and Ultra Compact Dwarfs in the Virgo Cluster
Youkyung Ko, Ho Seong Hwang, Myung Gyoon Lee +6
We present the results from a wide-field spectroscopic survey of globular clusters (GCs) in the Virgo Cluster. We obtain spectra for 201 GCs and 55 ultracompact dwarfs (UCDs) using…
A Submillimeter Continuum Survey of Local Dust-Obscured Galaxies
Jong Chul Lee, Ho Seong Hwang, Gwang-Ho Lee
We conduct a 350 micron dust continuum emission survey of 17 dust-obscured galaxies (DOGs) at z = 0.05-0.08 with the Caltech Submillimeter Observatory (CSO). We detect 14 DOGs with…
The Scaling of Stellar Mass and Central Stellar Velocity Dispersion for Quiescent galaxies at z < 0.7
H. Jabran Zahid, Margaret Geller, Daniel Fabricant +1
We examine the relation between stellar mass and central stellar velocity dispersion-the M-sigma relation-for massive quiescent galaxies at z<0.7. We measure the local relation fro…
Compact E+A Galaxies as a Progenitor of Massive Compact Quiescent Galaxies at 0.2<z< 0.8
H. Jabran Zahid, Nicholas Baeza Hochmuth, Margaret J. Geller +5
We search the Sloan Digital Sky Survey and the Baryon Oscillation Sky Survey to identify ~5500 massive compact quiescent galaxy candidates at 0.2<z<0.8. We robustly classify a subs…
SHELS: Complete Redshift Surveys of Two Widely Separated Fields
Margaret J. Geller, Ho Seong Hwang, Ian P. Dell'Antonio +3
The SHELS (Smithsonian Hectospec Lensing Survey) is a complete redshift survey covering two well-separated fields (F1 and F2) of the Deep Lens Survey. Both fields are more than 94%…
Catalogs of Compact Groups of Galaxies from the Enhanced SDSS DR12
Jubee Sohn, Margaret J. Geller, Ho Seong Hwang +2
We apply a friends-of-friends algorithm to an enhanced SDSS DR12 spectroscopic catalog including redshift from literature to construct a catalog of compact groups of g…
Stellar Populations of Early-type Galaxies with Mid-Infrared Excess Emission
Jongwan Ko, Haeun Chung, Ho Seong Hwang +1
We present a stellar population analysis of quiescent (without H emission) and bright ( 21.5) early-type galaxies (ETGs) with recent star formation. The ETGs are s…
Compact Groups of Galaxies with Complete Spectroscopic Redshifts in the Local Universe
Jubee Sohn, Ho Seong Hwang, Margaret J. Geller +4
Dynamical analysis of compact groups provides important tests of models of compact group formation and evolution. By compiling 2066 redshifts from FLWO/FAST, from the literature, a…
