In this paper, the author examines what happens to the quasar mass-luminosity relationship if the method used to calculate the black hole masses is biased, as well the physical implications of different corrections that have been suggested.
Mergers play an important role in any galaxy’s evolution. A coincidental observation of a quasar and companion galaxy linked by a photoionized gas bridge offers an exclusive look at the merger process at moderate redshift.
When galaxies merge, the super-massive black holes at their center can merge as well. General relativity predicts that the newly merged black hole can, in forming, be kicked with a large velocity out of the galactic center!
Using data from Herschel’s science demonstration field, the authors of this paper investigate the connection between star formation and activity of a galaxy’s central engine.
How do you enrich the ICM at great distances from the BCG? With an AGN!
An investigation of a large sample of type I and II AGN yields a unification scheme based on accretion rate.
