Research Abstract |
We searched for supermassive black holes(SMBHs) in their growing phase, and studied accretion processes in such a growing state. We successfully discovered relatively low-mass SMBHs and growing(i. e., large accretion rate) SMBHs by utilizing rapid X-ray variability from a large data set of XMM-Newton. We also discovered a new class of SMBH showing prominent soft X-ray, which is likely to be in a new state, and properties of an accretion disk in such a circumstance are studied.
