The origin of the most massive high redshift quasars
Event Start:
2020-07-20T15:00:00
Event End:
2020-07-20T16:00:00
Event Information:
The discovery of billion solar mass quasars at redshifts of 6–7 challenges our understanding of the early Universe; how did such massive objects form in the first billion years? Observational constraints and numerical simulations increasingly favour the "direct collapse" scenario. In this case, an atomically-cooled halo of primordial composition accretes rapidly onto a single protostellar core, ultimately collapsing through the Chandrasekhar-Feynman instability to produce a supermassive (~100,000 solar mass) "seed" black hole.
