The Number of Supernovae from Primordial Stars in the Universe
John H. Wise, Tom Abel
Recent simulations of the formation of the first luminous objects in the universe predict isolated very massive stars to form in dark matter halos with virial temperatures large en…
Two distinct ancient components in the Sculptor Dwarf Spheroidal Galaxy: First Results from DART
Eline Tolstoy, M. J. Irwin, A. Helmi +14
We have found evidence for the presence of two distinct ancient stellar components (both geq 10 Gyr old) in the Sculptor dwarf spheroidal galaxy. We used the ESO Wide Field Imager…
Initial Ionization of Compressible Turbulence
Yuexing Li, Mordecai-Mark Mac Low, Tom Abel
We study the effects of the initial conditions of turbulent molecular clouds on the ionization structure in newly formed H_{ii} regions, using three-dimensional, photon-conserving…
Introducing Enzo, an AMR Cosmology Application
Brian W. O'Shea, Greg Bryan, James Bordner +4
In this paper we introduce Enzo, a 3D MPI-parallel Eulerian block-structured adaptive mesh refinement cosmology code. Enzo is designed to simulate cosmological structure formation,…
