Quasar host galaxies
The discovery that the formation and evolution of supermassive black holes and their host spheroids are intimately related has given new impetus to the study of quasar host galaxies. As a result, many current studies of quasar hosts are focused on exploring the redshift evolution of the black-hole:spheroid relation, and the evolution of the massive galaxy population as a whole. This brief revie...
متن کاملOn Quasar Masses and Quasar Host Galaxies
The mass of massive black holes in quasar cores can be deduced using the typical velocities of Hβ-emitting clouds in the Broad Line Region (BLR) and the size of this region. However, this estimate depends on various assumptions and is susceptible to large systematic errors. The Hβ-deduced black hole mass in a sample of 14 bright quasars is found here to correlate with the quasar host galaxy lum...
متن کاملQuasar outflows and the formation of dwarf galaxies
In this paper we propose a scenario for the formation of a population of baryon rich, dark matter deficient dwarf galaxies at high redshift from the mass swept out in the Inter-Galactic Medium (IGM) by energetic outflows from luminous quasars. We predict the intrinsic properties of these galaxies, and examine the prospects for their observational detection in the optical, X-ray and radio waveba...
متن کاملStar Formation Quenching in Quasar Host Galaxies
Galaxy evolution is likely to be shaped by negative feedback from active galactic nuclei (AGN). In the whole range of redshifts and luminosities studied so far, galaxies hosting an AGN frequently show fast and extended outflows consisting in both ionized and molecular gas. Such outflows could potentially quench the start formation within the host galaxy, but a clear evidence of negative feedbac...
متن کاملThe ages of quasar host galaxies
We present the results of fitting deep off-nuclear optical spectroscopy of radio-quiet quasars, radio-loud quasars and radio galaxies at z ≃ 0.2 with evolutionary synthesis models of galaxy evolution. Our aim was to determine the age of the dynamically dominant stellar populations in the host galaxies of these three classes of powerful AGN. Some of our spectra display residual nuclear contamina...
