Locally Biased Galaxy Formation and Large Scale Structure
Vijay K. Narayanan, Andreas Berlind, David H. Weinberg
We examine the influence of the morphology-density(MD) relation and a wide range of simple models for biased galaxy formation on statistical measures of large scale structure. We c…
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…
Closing in on Omega_0: The Amplitude of Mass Fluctuations from Galaxy Clusters and the Lyman-alpha Forest
David H. Weinberg, Rupert A. C. Croft, Lars Hernquist +2
We estimate the value of the matter density parameter Ω_0 by combining constraints from the galaxy cluster mass function with Croft et al.'s recent measurement of the mass power sp…
The Power Spectrum of Mass Fluctuations Measured from the Lyman-alpha Forest at Redshift z=2.5
Rupert A. C. Croft, David H. Weinberg, Max Pettini +2
We measure the linear power spectrum of mass density fluctuations at redshift z=2.5 from the \lya forest absorption in a sample of 19 QSO spectra, using the method introduced by Cr…
The Low Redshift Lyman Alpha Forest in Cold Dark Matter Cosmologies
Romeel Dave', Lars Hernquist, Neal Katz +1
We study the physical origin of the low-redshift Lyman alpha forest in hydrodynamic simulations of four CDM cosmologies. Our main conclusions are insensitive to the cosmological mo…
The Clustering of High Redshift Galaxies in the Cold Dark Matter Scenario
Neal Katz, Lars Hernquist, David H. Weinberg
We investigate the clustering of high redshift galaxies in five variants of the cold dark matter (CDM) scenario, using hydrodynamic cosmological simulations that resolve the format…
Reconstruction Analysis of Galaxy Redshift Surveys: A Hybrid Reconstruction Method
Vijay K. Narayanan, David H. Weinberg
In reconstruction analysis of galaxy redshift surveys, one works backwards from the observed galaxy distribution to the primordial density field in the same region, then evolves th…
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…
Constraining the Metallicity of the Low Density Lyman-alpha Forest Using OVI Absorption
Romeel Davé, Uffe Hellsten, Lars Hernquist +2
We search for OVI absorption in a Keck HIRES spectrum of the z=3.62 quasar Q1422+231. Comparison of CIV measurements to cosmological simulations shows that \lya forest absorbers wi…
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…
Mock 2dF and SDSS galaxy redshift surveys
Shaun Cole, Steve Hatton, David H. Weinberg +1
We present a comprehensive set of mock 2dF and SDSS galaxy redshift surveys constructed from a set of large, high-resolution cosmological N-body simulations. The radial selection f…
