On the Kennicutt-Schmidt relation of low-metallicity high-redshift galaxies
Nickolay Y. Gnedin, Andrey V. Kravtsov
We present results of self-consistent, high-resolution cosmological simulations of galaxy formation at z~3. The simulations employ recently developed recipe for star formation base…
Modeling The Large Scale Bias of Neutral Hydrogen
Felipe Marin, Nickolay Y. Gnedin, Hee-Jong Seo +1
We present new analytical estimates of the large scale bias of neutral hydrogen (HI). We use a simple, non-parametric model which monotonically relates the total mass of a halo M_t…
Computational Eulerian Hydrodynamics and Galilean Invariance
Brant E. Robertson, Andrey V. Kravtsov, Nickolay Y. Gnedin +2
Eulerian hydrodynamical simulations are a powerful and popular tool for modeling fluids in astrophysical systems. In this work, we critically examine recent claims that these metho…
Computer Simulations of Cosmic Reionization
Hy Trac, Nickolay Y. Gnedin
The cosmic reionization of hydrogen was the last major phase transition in the evolution of the universe, which drastically changed the ionization and thermal conditions in the cos…
Analysis of methods for detecting the proximity effect in quasar spectra
Aldo Dall'Aglio, Nickolay Y. Gnedin
Using numerical simulations of structure formation, we investigate multiple methods of determining the strength of the proximity effect in the HI Lyalpha forest. We analyze three h…
Cosmological Radiative Transfer Comparison Project II: The Radiation-Hydrodynamic Tests
Ilian T. Iliev, Daniel Whalen, Garrelt Mellema +14
The development of radiation hydrodynamical methods that are able to follow gas dynamics and radiative transfer self-consistently is key to the solution of many problems in numeric…
