Poster Title: Growth of massive black holes by super-Eddington accretion
Abstract: We discuss a couple of Narrow-Line Seyfert 1 galaxies whose accretion rate, in the unit of Eddington accretion rate, seem to be the highest (Mdot sim 1000 L_Edd/c^2) among Active Galactic Nuclei (AGNs). Theoretical arguments in (broad-band) spectral modeling will be presented. Then, based on the average accretion rate and the duration of super-Eddington AGNs, we discuss to what extent massive black holes grow via super-Eddington accretion, and compare it with the growth in sub-Eddington accretion regime.
