摘要:
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, e.g, the driving and maintaining mechanism of the extremely large star formation rate, the feeding of central SMBH, and the feedback effects associated with the AGN activity. In this talk I will introduce 1) the construction of 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, and 2) the multi-wavelength follow-ups (Gemini/GMOS, ALMA, NuSTAR) for several galaxies selected from the sample, which show extremely fast, galaxy scale, multi-phase outflows.
