An Upper Limit to the Degree of Evolution between Supermassive Black Holes and Their Host Galaxies
... All of these predictions appear to be opposite the ob- servations, with quasar spectra dominated by post-starburst activity (Vanden Berk et al. 2006), typically early-type, bulge-dominated hosts (especially in the ...

Tidal disruption of stars by supermassive black holes: The X-ray view
... – TDEs are markers of recoiling SMBHs. Tidal disruptions of stars in the star cluster bound to an ejected SMBH after GW recoil will produce off-center (or even intergalactic) flares of quasar-like luminosity, and in that ...
