09/30/2016Astro SeminarZoltan HaimanRapid Formation of the First Supermassive Black Holes [ -- Description ]

Description: Supermassive black holes (SMBHs) are common in local galactic nuclei, and SMBHs as massive as several billion solar masses already exist at redshift z>6. The earliest SMBHs may have been assembled by the combination of mass accretion onto stellar-mass seed BHs, left behind by an early generation of massive stars, and by numerous mergers between these growing seeds. Alternatively, SMBHs could result from the rapid accumulation of gas in rare special environments in the early universe, where the primordial gas can shed its angular momentum and collapse without cooling and fragmenting, while also evading radiative feedback. I will discuss these two competing scenarios, and discuss how they might be distinguished by future observations. (2:00 PM, Meyer 5th Fl. CCPP Lounge)
