VOBOZ: An Almost-Parameter-Free Halo-Finding Algorithm
Mark C. Neyrinck, Nickolay Y. Gnedin, Andrew J. S. Hamilton
We have developed an algorithm to find haloes in an N-body dark matter simulation, called VOBOZ (VOronoi BOund Zones), which has as little dependence on free parameters as we can m…
Cosmology from Large Scale Structure
Andrew Hamilton, Nick Gnedin, Max Tegmark +1
We report on the linear matter power spectrum reconstructed from the Lyman alpha forest, on baryonic wiggles in the galaxy power spectrum, and on how to measure real space (as oppo…
Redshift of reionization: are we there yet?
Nickolay Y. Gnedin
Comparison of the observed evolution of the Ly-alpha transmitted flux in the spectra of four highest redshift quasars discovered by SLOAN survey with the theoretical prediction for…
CO emission from high redshift
Nickolay Y. Gnedin, Joseph Silk, Marco Spaans
Future observations with ALMA will be able to detect star-forming primordial gal axies, and perhaps even their dwarf spheroidal satellites, in CO emission lines at redshifts approa…
The Column Density Distribution of the Lyman-Alpha Forest: A Measure of Small Scale Power
Lam Hui, Nickolay Y. Gnedin, Yu Zhang
Absorption lines in the Lyman-alpha forest can be thought of as peaks in neutral hydrogen density along lines of sight. The column density distribution (the number density of absor…
