Very Large H II Regions Around Proto-Clusters of Galaxies During Reionization
Renyue Cen
The physical basis for the belief that the abundant old dwarf galaxies seen in present-day galaxy clusters formed before reionization of the universe is very compelling, because (1…
Properties of Cold Dark Matter Halos at z>6
Renyue Cen, Feng Dong, Paul Bode +1
We compute the properties of dark matter halos with mass $10^{6.5}-10^9\msun$ at redshift in the standard cold dark matter cosmological model, utilizing a very high resolu…
Dependence of Star Formation Rate on Overdensity
Kentaro Nagamine, Renyue Cen, Jeremiah P. Ostriker
We use a large-scale Lambda-CDM hydrodynamical simulation to assess the dependence of the cosmic Star Formation Rate (SFR) on overdensity of luminosity. The `morphology-density rel…
New Statistical Measures of the Lya Forest Spectra for Accurate Comparison to Theoretical Models
J. Miralda-Escude, M. Rauch, W. L. W. Sargent +6
We propose a new method of analysis for the \lya forest, namely to measure the 1-point and 2-point joint probability distribution of the transmitted flux. The results for a sample…
On the Clustering of Lyman Alpha Clouds
Renyue Cen, Steven Phelps, Jordi Miralda-Escudé +1
We examine the correlational property of $\lya$ clouds in detail and compare it to that of mass and galaxies. We show that the correlation strength of $\lya$ clouds is somewhat wea…
Testing Cosmological Models by Gravitational Lensing: I. Method and First Applications
Joachim Wambsganss, Renyue Cen, Jeremiah P. Ostriker
Gravitational lensing directly measures mass density fluctuations along the lines of sight to very distant objects. No assumptions need to be made concerning bias, the ratio of flu…
