Regulated star formation in forming disk galaxies under ultraviolet radiation background
Hajime Susa
We perform radiation hydrodynamics simulations on the evolution of galactic gas disks irradiated by ultraviolet radiation background. We find gas disks with N_H > 10^21 cm^-2 expos…
Photodissociation feedback of Population III stars \\on their neighbor prestellar cores
Hajime Susa
We investigate the star formation process in primordial environment in the presence of radiative feedback by other population III stars formed earlier. In this paper, we focus our…
Secondary Star Formation in a Population III Object
Hajime Susa, Masayuki Umemura
We explore the possibility of subsequent star formation after a first star forms in a Pop III object, by focusing on the radiation hydrodynamic (RHD) feedback brought by ionizing p…
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…
Effects of Early Cosmic Reionization on the Substructure Problem in Galactic Halo
Hajime Susa, Masayuki Umemura
Recent observations on the cosmic microwave background by Wilkinson Microwave Anisotropy Probe(WMAP) strongly suggest that the reionization of the universe took place quite early (…
The Structure and Evolution of Early Cosmological HII Regions
T. Kitayama, N. Yoshida, H. Susa +1
We study the formation and evolution of HII regions around the first stars formed at z=10-30. We use a one-dimensional Lagrangian hydrodynamics code which self-consistently incorpo…
