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…
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…
Adaptive Mesh Refinement Simulations of the Ionization Structure and Kinematics of Damped Ly Systems with Self-consistent Radiative Transfer
Alexei O. Razoumov, Michael L. Norman, Jason X. Prochaska +1
We use high resolution Eulerian hydrodynamics simulations to study kinematic properties of the low ionization species in damped Ly-alpha systems at redshift z=3. Our adaptive mesh…
Fully Threaded Transport Engine: New Method for Multi-Scale Radiative Transfer
A. O. Razoumov, C. Y. Cardall
A new, very fast method for 3D radiative transfer on fully threaded grids with arbitrarily high angular resolution is presented. The method uses completely cell-based discretizatio…
