On the masses of black-holes in radio-loud quasars
نویسندگان
چکیده
The central black-hole masses of 85 radio-loud quasars are estimated using available data of Hβ line-width and optical continuum luminosity. The vast majority of the quasars in this sample have black-hole masses larger than 108M⊙, while a few quasars may contain relatively smaller black-holes. It is found that the radio-loudness decreases with the black-hole mass.

The role of black hole mass in quasar radio activity
We use a homogeneous sample of ∼ 300, 0.3 < ∼ z < ∼ 3, radio-loud quasars drawn from the FIRST and 2dF QSO surveys to investigate a possible dependence of radio activity on black-hole mass. By analyzing composite spectra for the populations of radio-quiet and radio-loud QSOs – chosen to have the same redshift and luminosity distribution – we find with high statistical significance that radio-lo...
متن کاملStellar Disruption by Supermassive Black Holes and the Quasar Radio Loudness Dichotomy
The origin of the dichotomy of radio loudness among quasars can be explained using recent findings that the mass of the central supermassive black hole (SMBH) in extended radio-loud quasars is systematically a few times that of their counterparts in radio-quiet quasars. This sensitive dependence of radio jet ejection upon SMBH mass probably arises from the blockage of jets by the presence of su...
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 relationship between radio luminosity and black-hole mass in optically-selected quasars
Using a sample of more than 6000 quasars from the Sloan digital sky survey (SDSS) we compare the black-hole mass distributions of radio-loud and radio-quiet quasars. Based on the virial black-hole mass estimator the radio-loud quasars (RLQs) are found to harbour systematically more massive black holes than radio-quiet quasars (RQQs) with very high significance (≫ 99.99%), with mean black-hole m...
متن کاملHubble Space Telescope ultraviolet spectroscopy of blazars: emission lines properties and black hole masses
ABSTRACT The ultraviolet (UV) spectra of 16 blazars (< z >≃ 1) from the archives of the Hubble Space Telescope Faint Object Spectrograph have been analyzed in order to study in a systematic way the properties of their broad UV emission lines. We find that the luminosities of the most prominent and intense lines, Lyα and C IV λ1549, are similar to those of normal radio-loud quasars at comparable...
