The Masses of Lyman Break Galaxies
Joel R. Primack, Risa H. Wechsler, Rachel S. Somerville
Data on galaxies at high redshift, identified by the Lyman-break photometric technique, can teach us about how galaxies form and evolve. The stellar masses and other properties of…
Concentrations and Assembly Histories of Dark Matter Halos
Risa H. Wechsler, James S. Bullock, J. R. Primack +2
We study the relation between the density profiles of dark matter halos and their mass assembly histories, using a statistical sample of halos in a high-resolution N-body simulatio…
Clustering in the Las Campanas Distant Cluster Survey
Anthony H. Gonzalez, Dennis Zaritsky, Risa H. Wechsler
We utilize a sample of galaxy clusters at 0.35<z<0.6 drawn from the Las Campanas Distant Cluster Survey (LCDCS) to provide the first non-local constraint on the cluster-cluster spa…
Tracing Cosmic Evolution with the Las Campanas Distant Cluster Survey
Anthony H. Gonzalez, Julianne J. Dalcanton, Amy E. Nelson +3
The Las Campanas Distant Cluster Survey (LCDCS), which contains over 1000 cluster candidates at z>0.3, is a unique sample with which to probe the evolution of both cluster galaxies…
Clustering of high-redshift galaxies: relating LBGs to dark matter halos
Risa H. Wechsler, James S. Bullock, Rachel S. Somerville +4
We investigate the clustering properties of high-redshift galaxies within three competing scenarios for assigning luminous galaxies to dark matter halos from N-body simulations: a…
