Warm-hot gas in groups and galaxies toward H2356-309

Rik J. Williams, John S. Mulchaey, Juna A. Kollmeier

We present a detailed analysis of the galaxy and group distributions around three reported X-ray absorption line systems in the spectrum of the quasar H2356-309. Previous studies a…

HST/WFC3 Confirmation of the Inside-Out Growth of Massive Galaxies at 0<z<2 and Identification of their Star Forming Progenitors at z~3

Shannon G. Patel, Pieter G. van Dokkum, Marijn Franx +6

We study the structural evolution of massive galaxies by linking progenitors and descendants at a constant cumulative number density of n_c=1.4x10^{-4} Mpc^{-3} to z~3. Structural…

The Evolution of Mass-size Relation for Lyman Break Galaxies From z=1 to z=7

Moein Mosleh, Rik J. Williams, Marijn Franx +6

For the first time, we study the evolution of the stellar mass-size relation for star-forming galaxies from z ~ 4 to z ~ 7 from Hubble-WFC3/IR camera observations of the HUDF and E…

A direct measurement of hierarchical growth in galaxy groups since z~1

Rik J. Williams, Daniel D. Kelson, John S. Mulchaey +3

We present the first measurement of the evolution of the galaxy group stellar mass function (GrSMF) to redshift z>~1 and low masses (M*>10^12 Msun). Our results are based on early…

The Carnegie-Spitzer-IMACS Redshift Survey of Galaxy Evolution since z=1.5: I. Description and Methodology

Daniel D. Kelson, Rik J. Williams, Alan Dressler +6

We describe the Carnegie-Spitzer-IMACS (CSI) Survey, a wide-field, near-IR selected spectrophotometric redshift survey with the Inamori Magellan Areal Camera and Spectrograph (IMAC…
