DESCRIPTION:Using a “wedding cake” combination of X-ray+multi-waveleng
 th\nsurveys\, we measure the growth of supermassive black holes at the cen
 ters of\ngalaxies over the last ~12 billion years. Most Active Galactic Nu
 clei are\nheavily obscured and thus look like inactive galaxies in optical
  surveys\, so\nour census effectively quadruples the amount of accretion\,
  and thus the\namount of energy deposited in AGN host galaxies. However\, 
 contrary to\nleading models\, our data suggest that for only a minority of
  galaxies does\nmerger-triggered AGN “feedback” cause rapid quenching 
 of star formation.\n\n\n\nHosted by: IoA Equality Diversity and Inclusion
