Damped Lyman alpha Absorbing Galaxies At Low Redshifts z<1 From Hierarchical Galaxy Formation Models
Katsuya Okoshi, Masahiro Nagashima
We investigate Damped Ly-alpha absorbing galaxies (DLA galaxies) at low redshifts z<1 in the hierarchical structure formation scenario to clarify the nature of DLA galaxies because…
Chemical Enrichment in Damped Lyman Alpha Systems From Hierarchical Galaxy Formation Models
Katsuya Okoshi, Masahiro Nagashima, Naoteru Gouda +1
We investigate chemical enrichment in Damped Lyman alpha (DLA) systems in the hierarchical structure formation scenario using a semi-analytic model of galaxy formation. The model d…
Evolution of Multiphase Hot Interstellar Medium in Elliptical Galaxies
Yutaka Fujita, Junji Fukumoto, Katsuya Okoshi
We present the results of a variety of simulations concerning the evolution of multiphase (inhomogeneous) hot interstellar medium (ISM) in elliptical galaxies. We assume the gases…
Multiphase Chemical Evolution in Elliptical Galaxies
Y. Fujita, J. Fukumoto, K. Okoshi
The recent {\em ASCA} results show that the iron abundance of the X-ray gas of elliptical galaxies is less than the solar abundance ($Z_{\sun}$). The observed low iron abundance is…
