Radiation-Hydrodynamical Collapse of Pregalactic Clouds in the Ultraviolet Background
T. Kitayama, Y. Tajiri, M. Umemura +2
To elucidate the effects of the UV background radiation on the collapse of pregalactic clouds, we implement a radiation-hydrodynamical calculation, combining one-dimensional spheri…

A Criterion for Photoionization of Pregalactic Clouds Exposed to Diffuse Ultraviolet Background Radiation
Yukiko Tajiri, Masayuki Umemura
To elucidate the permeation of cosmic ultraviolet (UV) background radiation into a pregalactic cloud and subsequent ionization, the frequency-dependent radiative transfer equation…
