Galaxy Mergers and Dark Matter Halo Mergers in LCDM: Mass, Redshift, and Mass-Ratio Dependence
Kyle R. Stewart, James S. Bullock, Elizabeth J. Barton +1
We employ a high-resolution LCDM N-body simulation to present merger rate predictions for dark matter halos and investigate how common merger-related observables for galaxies--such…
The Assembly of Galaxy Clusters
Joel C. Berrier, Kyle R. Stewart, James S. Bullock +3
We study the formation of fifty-three galaxy cluster-size dark matter halos formed within a pair of cosmological LCDM N-body simulations, and track the accretion histories of clust…
A Candidate Brightest Proto-Cluster Galaxy at z = 3.03
Jeff Cooke, Elizabeth J. Barton, James S. Bullock +2
We report the discovery of a very bright (m_R = 22.2) Lyman break galaxy at z = 3.03 that appears to be a massive system in a late stage of merging. Deep imaging reveals multiple p…
