Simulating the Formation of the Local Galaxy Population
H. Mathis, G. Lemson, V. Springel +4
We simulate the formation and evolution of the local galaxy population starting from initial conditions with a smoothed linear density field which matches that derived from the IRA…
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…
Concentrations of Dark Halos from their Assembly Histories
Risa H. Wechsler, James S. Bullock, Joel R. Primack +2
(abridged) 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-bod…
Cosmic Flows: A Status Report
Stephane Courteau, Avishai Dekel
We give a brief review of recent developments in the study of the large-scale velocity field of galaxies since the international workshop on Cosmic Flows held in July 1999 in Victo…
Modeling Angular-Momentum History in Dark-Matter Halos
Ariyeh H. Maller, Avishai Dekel, Rachel S. Somerville
We model the acquisition of spin by dark-matter halos in semi-analytic merger trees. We explore two different algorithms; one in which halo spin is acquired from the orbital angula…
Testing Tidal-Torque Theory: II. Alignment of Inertia and Shear and the Characteristics of Proto-haloes
Cristiano Porciani, Avishai Dekel, Yehuda Hoffman
We investigate the cross-talk between the two key components of tidal-torque theory, the inertia (I) and shear (T) tensors, using a cosmological N-body simulation with thousands of…
Testing Tidal-Torque Theory: I. Spin Amplitude and Direction
Cristiano Porciani, Avishai Dekel, Yehuda Hoffman
We evaluate the success of linear tidal-torque theory (TTT) in predicting galactic-halo spin using a cosmological N-body simulation with thousands of well-resolved haloes. The prot…
