A Complete Spectroscopic Census of Abell 2029: A Tale of Three Histories
Jubee Sohn, Margaret J. Geller, H. Jabran Zahid +1
A rich spectroscopic census of members of the local massive cluster Abell 2029 includes 1215 members of A2029 and its two infalling groups, A2033 and a Southern Infalling Group (SI…
Quiescent Galaxy Size and Spectroscopic Evolution: Combining HSC Imaging and Hectospec Spectroscopy
Ivana Damjanov, H. Jabran Zahid, Margaret J. Geller +3
We explore the relations between size, stellar mass and average stellar population age (indicated by D indices) for a sample of intermediate-redshift galaxies f…
The Massively Accreting Cluster A2029
Jubee Sohn, Margaret J. Geller, Stephen A. Walker +3
We explore the structure of galaxy cluster Abell 2029 and its surroundings based on intensive spectroscopy along with X-ray and weak lensing observations. The redshift survey inclu…
Gemini/GMOS Spectroscopy of Globular Clusters in the Merger Remnant Galaxy M85
Youkyung Ko, Myung Gyoon Lee, Hong Soo Park +3
M85 is a peculiar S0 galaxy in Virgo and is a well-known merger remnant. In this paper, we present the first spectroscopic study of globular clusters (GCs) in M85. We obtain spectr…
Stellar Velocity Dispersion: Linking Quiescent Galaxies to their Dark Matter Halos
H. Jabran Zahid, Jubee Sohn, Margaret J. Geller
We analyze the Illustris-1 hydrodynamical cosmological simulation to explore the stellar velocity dispersion of quiescent galaxies as an observational probe of dark matter halo vel…
The HectoMAP Cluster Survey - I. redMaPPer Clusters
Jubee Sohn, Margaret J. Geller, Kenneth J. Rines +3
We use the dense HectoMAP redshift survey to explore the properties of 104 redMaPPer cluster candidates. The redMaPPer systems in HectoMAP cover the full range of richness and reds…
The HectoMAP Cluster Survey - II. X-ray Clusters
Jubee Sohn, Gayoung Chon, Hans Böhringer +5
We apply a friends-of-friends algorithm to the HectoMAP redshift survey and cross-identify associated X-ray emission in the ROSAT All-Sky Survey data (RASS). The resulting flux lim…
