Evidence for a black hole in a radio-quiet quasar nucleus
نویسندگان
چکیده
We present the first milli-arcsecond resolution radio images of a radio-quiet quasar, detecting a high brightness temperature core with data from the VLBA. On maps made with lower-frequency data from MERLIN and the VLA jets appear to emanate from the core in opposite directions, which correspond to radio-emission on arcsecond scales seen with the VLA at higher frequencies. These provide strong evidence for a black-hole–based jet-producing central engine, rather than a starburst, being responsible for the compact radio emission in this radio-quiet quasar.

The Radio Loudness Dichotomy: Environment or Black-hole Mass?
The results of a comprehensive study of the cluster environments and black-hole masses of an optically matched sample of radio-loud and radio-quiet quasars are presented. No evidence is found for a difference in large-scale environments, with both quasar classes found to be located in clusters of Abell class ∼ 0 . Conversely, virial black-hole mass estimates based on Hβ line-widths show a clear...
متن کاملQuasar Clustering from Sdss Dr5: Dependences on Physical Properties
Using a homogenous sample of 38,208 quasars with a sky coverage of ∼ 4000deg2 drawn from the SDSS Data Release Five quasar catalog, we study the dependence of quasar clustering on luminosity, virial black hole mass, quasar color, and radio loudness. At z < 2.5, quasar clustering depends weakly on luminosity and virial black hole mass, with typical uncertainty levels ∼ 10% for the measured corre...
متن کاملMassive Black Holes at High Redshifts
Black holes with masses Mbh ∼ 10M⊙ dominate the accretion history of the Universe. These black hole masses are typical of those found in radio-selected galaxies today, suggesting that the giant elliptical hosts of low redshift radio galaxies were the hosts of powerful, mostly radio-quiet, quasars in the high redshift Universe. The reason that all radio galaxies are found in such hosts may be th...
متن کاملThe Optical-uv Emissivity of Quasars: Dependence on Black Hole Mass and Radio Loudness
We analyzed a large sample of radio-loud and radio-quiet quasar spectra at redshift 1.0 ≤ z ≤ 1.2 to compare the inferred underlying quasar continuum slopes (after removal of the host galaxy contribution) with accretion disk models. The latter predict redder (decreasing) α3000 continuum slopes (Lν ∝ να at 3000Å) with increasing black hole mass, bluer α3000 with increasing luminosity at 3000Å, a...
متن کاملThe Host Galaxies of Radio-loud and Radio-quiet Quasars
I review our knowledge of the properties of the host galaxies of radioloud and radio-quiet quasars, both in comparison to each other and in the context of the general galaxy population. It is now clear that the hosts of radio-loud and radio-quiet quasars with MV < −23.5 are virtually all massive elliptical galaxies. The masses of these spheroids are as expected given the relationship between bl...
