Modeling Physical Processes at Galactic Scales and Above
Nickolay Y. Gnedin
What should these lectures be? The subject assigned to us is so broad that many books can be written about it. So, in planning these lectures I had several options. One would be to…
Cosmic Reionization On Computers III. The Clumping Factor
Alexander A. Kaurov, Nickolay Y. Gnedin
We use fully self-consistent numerical simulations of cosmic reionization, completed under the Cosmic Reionization On Computers (CROC) project, to explore how well the recombinatio…
Line Overlap and Self-Shielding of Molecular Hydrogen in Galaxies
Nickolay Y. Gnedin, Bruce T. Draine
The effect of line overlap in the Lyman and Werner bands, often ignored in galactic studies of the atomic-to-molecular transition, greatly enhances molecular hydrogen self-shieldin…
Accounting for baryonic effects in cosmic shear tomography: Determining a minimal set of nuisance parameters using PCA
Tim Eifler, Elisabeth Krause, Scott Dodelson +3
Systematic uncertainties that have been subdominant in past large-scale structure (LSS) surveys are likely to exceed statistical uncertainties of current and future LSS data sets,…
Cosmic Reionization On Computers II. Reionization History and Its Back Reaction on Early Galaxies
Nickolay Y. Gnedin, Alexander A. Kaurov
We compare the results from several sets of cosmological simulations of cosmic reionization, produced under Cosmic Reionization On Computers (CROC) project, with existing observati…
Cosmic Reionization On Computers I. Design and Calibration of Simulations
Nickolay Y. Gnedin
Cosmic Reionization On Computers (CROC) is a long-term program of numerical simulations of cosmic reionization. Its goal is to model fully self-consistently (albeit not necessarily…
