Ionization States and Plasma Structures of Mixed-morphology SNRs Observed with ASCA
Masahiro T. Kawasaki, Masanobu Ozaki, Fumiaki Nagase +2
We present the results of a systematic study using ASCA of the ionization state for six ``mixed-morphology'' supernova emnants (MMSNRs): IC 443, W49B, W28, W44, 3C391, and Kes 27.…

The oscillation effects on thermalization of the neutrinos in the universe with low reheating temperature
Kazuhide Ichikawa, Masahiro Kawasaki, Fuminobu Takahashi
We study how the oscillations of the neutrinos affect their thermalization process during the reheating period with temperature O(1) MeV in the early universe. We follow the evolut…
