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…
Close Galaxy Counts as a Probe of Hierarchical Structure Formation
Joel C. Berrier, James S. Bullock, Elizabeth J. Barton +3
Standard LCDM predicts that the major merger rate of galaxy-size dark matter halos rises rapidly with redshift. The average number of close companions per galaxy, Nc, is often used…
Galactic populations of radio and gamma-ray pulsars in the polar cap model
Peter L. Gonthier, Michelle S. Ouellette, Joel Berrier +2
We simulate the characteristics of the Galactic population of radio and -ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially distributed in the Galac…
