Orientation dependency of broad-line widths in quasars and consequences for black-hole mass estimation
In this paper we report new evidence that measurements of the broad-line widths in quasars are dependent on the source orientation, consistent with the idea that the broad-line region is flattened or disc-like. This reinforces the view derived from radio-selected samples, where the radio-core dominance has been used as a measure of orientation. The results presented here show a highly significa...
متن کاملA Photo-ionization Method for Black Hole Mass Estimation in Quasars
Determining the masses of the central compact object believed to power all active galactic nuclei is relevant to our understanding of their evolution and of their inner workings. Keys to present-day mass estimates are: (1) the assumption of line broadening due to virial motion of the emitting gas, (2) an estimate of the distance of broad-line emitting gas from the central compact object, and (3...
متن کاملBlack Hole Mass Estimates of Radio Selected Quasars
The black hole (BH) mass in the centre of AGN has been estimated for a sample of radio-selected flat-spectrum quasars to investigate the relationship between BH mass and radio properties of quasars. We have used the virial assumption with measurements of the Hβ FWHM and luminosity to estimate the central BH mass. In contrast to previous studies we find no correlation between BH mass and radio p...
متن کاملBroad-line region size and black hole mass in high-z AGN
In this contribution we brie y review the reverberation mapping technique and its results for low and intermediate luminosity AGNs. Then we present a monitoring campaign of high-luminosity high-redshift quasars which will extend these results by two orders of magnitude, probing the broad-line region size and black hole (BH) mass of luminous AGN at redshift ∼2-3.
متن کاملBlack Hole Masses of High-redshift Quasars
Black-hole masses of distant quasars cannot be measured directly, but can be estimated to within a factor 3 to 5 using scaling relationships involving the quasar luminosity and broad-line width. Why such relationships are reasonable is summarized. The results of applying scaling relationships to data of quasars at a range of redshifts (z ≤ 6.3) are presented. Luminous quasars typically have mas...
