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…
Secular Evolution of Barred Galaxies with Massive Central Black Holes
Shunsuke Hozumi, Lars Hernquist
The influence of central black holes on the dynamical evolution of bars in disk galaxies is examined. In particular, we use numerical simulation to estimate the minimum mass black…
Triaxial Halos and Cusps
Steinn Sigurdsson, Chris Mihos, Lars Hernquist +1
We present --body models for triaxial elliptical galaxies or halos of galaxies, which are fully self--gravitating, have near constant axis ratio as a function of radius and a $r…
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…
