DESCRIPTION:Speaker: Zoltan Haiman\nhosted by Tamas Hausel\nAbstract: Black
  holes as massive as several billion solar masses appeared within a billi
 on years after the Big Bang.  The origin of these objects remains a myste
 ry.  I will present three competing state-of-the art ideas on how such m
 assive black holes may have formed in the early universe from stellar bla
 ck  hole remnants\, via rapid gas accretion\, or via successive mergers.
   I will then discuss the role ofcircumbinary gas in mergers between blac
 k holes: for facilitating (or not) the early shrinking of their orbit\, p
 roducing unique observational signatures\, and impacting low-frequency gr
 avitational wave emission.  Upcoming observations with the recently laun
 ched James Webb Space Telescope (JWST) and with the space-based Laser In
 terferometer Space Antenna (LISA) will help us understand the origin of 
 massive black holes\, including the details of their mergers.
