DESCRIPTION:Broad wavelength X-shooter observations of a unique AGN sample
  at z=1.55 show extremely good agreement with predicted spectra of thin ac
 cretion disks.  The observations provide the first reliable black hole spi
 n measurements for a large number of luminous AGN.  They also show a clear
  “spin-up” for the most massive black holes\, which indicate either un
 usual evolution or a previously unnoticed selection effect.\n\nI shall com
 bine these findings with new data on super-Eddington accretion\, through s
 lim accretion disks\, in local and high redshift AGN.  This has important 
 consequences to the growth rate\, and evolution\, of all size black holes.
