"The Host Galaxies of
Dust-Reddened Quasars" |
|
The close relationship between the velocity dispersion of galaxy bulges and the masses of their central black holes is conventionally assumed to be due to a close link between quasar and star formation activity, presumably both triggered by galaxy mergers and interactions. However, imaging studies of the host galaxies of optically-selected quasars seem to indicate that most quasar hosts do not show obvious signs of recent merger or interaction activity. I will present the results of two studies of the hosts of infrared selected, dust reddened quasars, which indicate that a significantly larger fraction of quasar host galaxies may be involved in galaxy mergers/interactions than previously thought. |
