  • It has been proposed that supermassive black holes (SMBHs) are originated from direct-collapse black holes (DCBHs) that are formed at z & 10 in the primordial gas in the case that H2 cooling is suppressed by strong external radiation. In this work, we study the critical specific intensity J crit required for DCBH formation for various radiation spectral shapes by a series of one-zone calculations of a collapsing primordialgas cloud. We calculate the critical specific intensity at the Lyman… CONTINUE READING
