DLA kinematics and outflows from starburst galaxies
Alexei O. Razoumov
We present results from a numerical study of the multiphase interstellar medium in sub-Lyman-break galaxy protogalactic clumps. Such clumps are abundant at z=3 and are thought to b…
Can gravitational infall energy lead to the observed velocity dispersion in DLAs?
Alexei O. Razoumov, Michael L. Norman, Jason X. Prochaska +3
The median observed velocity width v_90 of low-ionization species in damped Ly-alpha systems is close to 90 km/s, with approximately 10% of all systems showing v_90 > 210 km/s at z…
Modeling Lyman continuum emission from young galaxies
Alexei O. Razoumov, Jesper Sommer-Larsen
Based on cosmological simulations, we model Lyman continuum emission from a sample of 11 high-redshift star forming galaxies spanning a mass range of a factor 20. Each of the 11 ga…
Escape of ionizing radiation from star forming regions in young galaxies
Alexei O. Razoumov, Jesper Sommer-Larsen
Using results from high-resolution galaxy formation simulations in a standard Lambda-CDM cosmology and a fully conservative multi-resolution radiative transfer code around point so…
Cosmological Radiative Transfer Codes Comparison Project I: The Static Density Field Tests
Ilian T. Iliev, Benedetta Ciardi, Marcelo A. Alvarez +13
Radiative transfer simulations are now at the forefront of numerical astrophysics. They are becoming crucial for an increasing number of astrophysical and cosmological problems; at…
Toward Five-dimensional Core-collapse Supernova Simulations
Christian Y. Cardall, Alexei O. Razoumov, Eirik Endeve +2
The computational difficulty of six-dimensional neutrino radiation hydrodynamics has spawned a variety of approximations, provoking a long history of uncertainty in the core-collap…
