The phase-space density distribution of dark matter halos
Liliya L. R. Williams, Crystal Austin, Eric Barnes +2
High resolution N-body simulations have all but converged on a common empirical form for the shape of the density profiles of halos, but the full understanding of the underlying ph…
Small-scale Substructure in Dark Matter Haloes: Where Does Galaxy Formation Come to an End?
James E. Taylor, Joseph Silk, Arif Babul
Models of structure formation based on cold dark matter predict that most of the small dark matter haloes that first formed at high redshift would have merged into larger systems b…
The Satellite-substructure Connection
James E. Taylor, Arif Babul, Joseph Silk
We describe our recent attempts to model substructure in dark matter halos down to very small masses, using a semi-analytic model of halo formation. The results suggest that numeri…
A Problem in Paleobiology
Barry D. Hughes, William J. Reed
We present a stochastic model for the size of a taxon in paleobiology, in which we allow for the evolution of new taxon members, and both individual and catastrophic extinction eve…
Observations of Candidate z=1.54 Quasar Host Clusters
Patrick Hall, Marcin Sawicki, C. J. Pritchet +2
We present new data on several z=1.54 radio-loud quasar fields from a sample of 31 at z=1-2 in which we have previously identified an excess population of predominantly red galaxie…
