Title: Massive spheroidal galaxies and their central super massive black holes under a violent formation phase
Speaker: 秋山正幸(東北大学)/ Masayuki Akiyama (Tohoku University)
Language: English
Abstract: Extreme starburst galaxies with star formation rate 100 times higher than the Milky Way galaxy are thought to represent the formation phase of the massive spheroidal galaxies and their central super massive black holes (SMBHs). Therefore, they are a key population of galaxies to unveil the physical mechanism behind the tight correlation between the spheroids and SMBHs. Now we are constructing a statistical sample of extreme starburst galaxies at z<1 utilizing a unique sample from AKARI-WISE-SDSS cross-matching and spectroscopic follow-up programs with Subaru and Seimei telescopes. Utilizing their closeness to us, we are trying to answer the questions with the physical mechanism; what are the driving and maintaining mechanism of the extremely large star formation rate ?, how is the central SMBH fed during the extreme starburst phase ?, and what are the feedback effects associated with the AGN activity.
