Saturn's largest satellite, Titan, transited the Crab Nebula on 5 January 2003. We observed this astronomical event with the {\it Chandra} X-ray Observatory. An ``occultation shado…
Properties of the Brightest Cluster Galaxy and Its Host Cluster
Haruyoshi Katayama, Kiyoshi Hayashida, Fumio Takahara +1
We investigate the relation between the properties of Brightest Cluster Galaxies (BCGs) and those of their host clusters. To quantify the properties of cluster hot gas, we employ t…
