Cosmology with the Lyman-alpha Forest
David H. Weinberg, Scott Burles, Rupert A. C. Croft +11
We outline the physical picture of the high-redshift Ly-alpha forest that has emerged from cosmological simulations, describe statistical characteristics of the forest that can be…
Cosmological Simulations with Scale-Free Initial Conditions II: Radiative Cooling
J. Michael Owen, David H. Weinberg, Jens V. Villumsen
The growth of structure from scale-free initial conditions is one of the most important tests of cosmological simulation methods, providing a realistically complex problem in which…
Cosmology from the structure of the Lyman-alpha forest
Rupert Croft, David Weinberg, Neal Katz +1
A convincing physical picture for the Lyman-alpha forest has emerged from simulations and related semi-analytic studies of structure formation models. Observations can be be used i…
Simulating Gas at High Redshift
Neal Katz, Lars Hernquist, David H. Weinberg
We discuss simulations of gas at high redshift. We briefly review the methods used and the results for quasar absorption lines. We present gas mass functions and galaxy correlation…
