Galaxy cluster mass accretion rates from IllustrisTNG
Michele Pizzardo, Margaret J. Geller, Scott J. Kenyon +2
We use simulated cluster member galaxies from Illustris TNG300-1 to develop a technique for measuring the galaxy cluster mass accretion rate (MAR) that can be applied directly to o…
An IllustrisTNG View of the Caustic Technique for Galaxy Cluster Mass Estimation
Michele Pizzardo, Margaret J. Geller, Scott J. Kenyon +2
The TNG300-1 run of the IllustrisTNG simulations includes 1697 clusters of galaxies with M covering the redshift range . We build mock spectros…
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…
Discovery of Nine Intermediate Redshift Compact Quiescent Galaxies in the Sloan Digital Sky Survey
Ivana Damjanov, Igor Chilingarian, Ho Seong Hwang +1
We identify nine galaxies with dynamical masses of M_dyn>10^10 M_sol as photometric point sources, but with redshifts between z=0.2 and z=0.6, in the Sloan Digital Sky Survey (SDSS…
On the Shapes and Structures of High-Redshift Compact Galaxies
M. Chevance, A. Weijmans, I. Damjanov +5
Recent deep Hubble Space Telescope WFC3 imaging suggests that a majority of compact quiescent massive galaxies at z~2 may contain disks. To investigate this claim, we have compared…
Red Nuggets at High Redshift: Structural Evolution of Quiescent Galaxies Over 10 Gyr of Cosmic History
Ivana Damjanov, Roberto G. Abraham, Karl Glazebrook +15
We present an analysis of the size growth seen in early-type galaxies over 10 Gyr of cosmic time. Our analysis is based on a homogeneous synthesis of published data from 17 spectro…
Extragalactic Fields Optimized for Adaptive Optics
Ivana Damjanov, Roberto G. Abraham, Karl Glazebrook +9
In this paper we present the coordinates of 67 55' x 55' patches of sky which have the rare combination of both high stellar surface density (>0.5 arcmin^{-2} with 13<R<16.5 mag) a…
