Size and Spectroscopic Evolution of HectoMAP Quiescent Galaxies
Ivana Damjanov, Jubee Sohn, Margaret J. Geller +2
The HectoMAP survey provides a complete, mass-limited sample of 30,231 quiescent galaxies with band Hyper Suprime-Cam Subaru Strategic Program (HSC SSP) imaging that spans the…
HectoMAP: The Complete Redshift Survey (Data Release 2)
Jubee Sohn, Margaret J. Geller, Ho Seong Hwang +3
HectoMAP is a dense redshift survey of 95,403 galaxies based primarily on MMT spectroscopy with a median redshift . The survey covers 54.64 square degrees in a 1.5$^\cir…
Tracing the Giant Outer Halo of the Mysterious Massive Disk Galaxy M104 I. Photometry of the Extended Globular Cluster Systems
Jisu Kang, Myung Gyoon Lee, In Sung Jang +4
M104 (NGC 4594, the Sombrero galaxy) is a mysterious massive early-type galaxy that shows a dominant bulge and a prominent disk. However, the presence of a halo in M104 has been el…
IllustrisTNG Snapshots for 10 Gyr of Dynamical Evolution of Brightest Cluster Galaxies and Their Host Clusters
Jubee Sohn, Margaret J. Geller, Mark Vogelsberger +1
We explore the redshift evolution of the dynamical properties of massive clusters and their brightest cluster galaxies (BCGs) at based on the IllustrisTNG-300 simulation. W…
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…
Co-evolution of the Brightest Cluster Galaxies and their Host Clusters in IllustrisTNG
Jubee Sohn, Margaret J. Geller, Mark Vogelsberger +1
We use the IllustrisTNG simulations to explore the dynamic scaling relation between massive clusters and their central galaxies (BCGs). The Illustris TNG300-1 simulation we use inc…
