The Stellar Mass Function for Nine Massive Galaxy Clusters in the Local Universe
Jong-In Park, Jubee Sohn, Margaret J. Geller +2
We measure galaxy stellar mass functions (SMFs) for nine of the most massive galaxy clusters in the local universe () using deep and complete spectroscopy from the…
Chandra follow up of the Hectospec Cluster Survey: Comparison of Caustic and Hydrostatic Masses and Constraints on the Hydrostatic Bias
Crispin H. A. Logan, Ben J. Maughan, Antonaldo Diaferio +4
Clusters of galaxies are powerful probes with which to study cosmology and astrophysics. However, for many applications an accurate measurement of a cluster's mass is essential. A…
A Spectroscopic View of the JWST/GTO Strong Lensing Cluster A1489
Kenneth J. Rines, Jubee Sohn, Margaret J. Geller +1
We discuss a spectroscopic survey of the strong lensing cluster A1489 that includes redshifts for 195 cluster members along with central velocity dispersions for 188 cluster member…
Mass accretion rates of the HectoMAP clusters of galaxies
M. Pizzardo, J. Sohn, M. J. Geller +2
We estimate the mass accretion rate (MAR) of the 346 clusters of galaxies in the HectoMAP Cluster Survey. The clusters span the redshift range and the mass ra…
The HectoMAP Cluster Survey: Spectroscopically Identified Clusters and their Brightest Cluster Galaxies (BCGs)
Jubee Sohn, Margaret J. Geller, Ho Seong Hwang +3
We apply a friends-of-friends (FoF) algorithm to identify galaxy clusters and we use the catalog to explore the evolutionary synergy between BCGs and their host clusters. We base t…
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…
