Galaxy Lookback Evolution Models -- a Comparison with Magneticum Cosmological Simulations and Observations
Rolf-Peter Kudritzki, Adelheid F. Teklu, Felix Schulze +4
We construct empirical models of star-forming galaxy evolution assuming that individual galaxies evolve along well-known scaling relations between stellar mass, gas mass and star f…
Velocity Dispersions of Massive Quiescent Galaxies from Weak Lensing and Spectroscopy
Yousuke Utsumi, Margaret J. Geller, Harus J. Zahid +6
We use MMT spectroscopy and deep Subaru Hyper Suprime-Cam (HSC) imaging to compare the spectroscopic central stellar velocity dispersion of quiescent galaxies with the effective di…
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…
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…
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…
