Spectroscopic Tomography: A First Weak Lensing Detection Using Spectroscopic Redshifts Only
Ian Dell'Antonio, Jubee Sohn, Margaret J. Geller +2
We describe the first spectroscopic tomographic (spectrotomographic) weak lensing measurement for a galaxy cluster based only on background galaxies with spectroscopically determin…
Velocity Dispersions of Brightest Cluster Galaxies and Their Host Clusters
Jubee Sohn, Margaret J. Geller, Antonaldo Diaferio +1
We explore connections between brightest cluster galaxies (BCGs) and their host clusters. We first construct a HeCS-omnibus cluster sample including 227 galaxy clusters within $0.0…
A Spectroscopic Census of X-ray Systems in the COSMOS Field
Jubee Sohn, Margaret J. Geller, H. Jabran Zahid
We investigate spectroscopic properties of galaxy systems identified based on deep X-ray observations in the COSMOS field. The COSMOS X-ray system catalog we use George et al. (201…
A Wide-field Photometric Survey of Globular Clusters in the Peculiar Early-type Galaxy M85
Youkyung Ko, Myung Gyoon Lee, Hong Soo Park +4
We survey globular clusters (GCs) in M85 using -band images of a field obtained with the MegaCam at the 3.6 m Canada-France-Hawaii Telescope. We i…
The Coevolution of Massive Quiescent Galaxies and Their Dark Matter Halos over the Last 6 Billion Years
H. Jabran Zahid, Margaret J. Geller, Ivana Damjanov +1
We investigate the growth of massive quiescent galaxies at based on the Sloan Digital Sky Survey and the Smithsonian Hectospec Lensing Survey---two magnitude limited spectr…
