| 英文摘要 | Black hole (BH) mass of type I active galactic nuclei (AGNs) can be measured or estimated through either reverberation mapping or empirical R-L relation, however, both of them suffer from uncertainties of the virial factor (f(BLR)), thus limiting the measurement accuracy. In this letter, we make an effort to investigate f(BLR) through polarized spectra of the broad-line regions (BLR) arisen from electrons in the equatorial plane. Given the BLR composed of discrete clouds with Keplerian velocity around the central BH, we simulate a large number of spectra of total and polarized flux with wide ranges of parameters of the BLR model and equatorial scatters. We find that the f(BLR)-distribution of polarized spectra is much narrower than that of total ones. This provides a way of accurately estimating BH mass from single spectropolarimetric observations of type I AGN whose equatorial scatters are identified. |
