SUMMARY:The long-term spin evolution of massive black holes: Insights from
  the NewHorizon simulation - Ricarda Beckman (IoA)

DESCRIPTION:Astrophysical black holes are described by two properties: the
 ir mass and their spin. While the mass evolution of massive black holes in
  the context of their host galaxies has been the subject of many detailed 
 studies\, comparatively little is understood about the spin of massive bla
 ck holes. Much like the mass\, the spin of black holes is thought to evolv
 e as the black hole coevolves with its host galaxy. Black hole spin has im
 portant consequences for the inner structure of the accretion disc\, which
  in affects the radiative efficiency of black hole feedback\, i.e. how muc
 h of the accreted mass is converted to energy and released by the black ho
 le. Black hole spin is also thought to power black hole jets via the Bland
 ford-Znajek mechanism. In this talk\, I will share insights into the long-
 term spin evolution of massive black holes as their host galaxies form and
  evolve\, using the NewHorizon simulation.
