DEEP X-RAY OBSERVATION OF THE PROTOTYPE GALAXY-GROUPS: THE NGC2300 GROUP
ABSTRACT
It is found by ASCA that there is some groups of galaxies which show extremely low metal abundance. There is no explanation for that. Then we propose to observe deeply a typical group of galaxies, NGC2300 group, which show low metal abundance, in order to investigate metal abundance distribution of low metal-abundance groups for the first time, and resolve the problem of metal abundance.
