Description
I will speak about an unconventional way of forming massive seed black holes (BHs) where pristine gas in the early universe is able to withstand fragmentation into stars, owing to a high level of extragalactic Lyman-Werner radiation, and directly collapses into a BH with mass 1.e4-1.e5 Msol. If these BHs can form and exist at z>6, there would be some interesting implications on the first-galaxy population which could be observed via JWST. I will also discuss the evolution of these BHs and their relation to the BH-bulge mass relation in the early universe.
