Abstract:
Using different kinds of velocity tracers derived from the broad
Hβ profile (in the mean or rms spectrum) and the corresponding
virial factors f, the central supermassive black hole masses (MBH)
are calculated for a compiled sample of 120 reverberation-mapped (RM)
active galactic nuclei (AGNs). For its subsample of RM AGNs with
measured stellar velocity dispersion (σ*), the multivariate
linear regression technique is used to calibrate the mean value f, as
well as the variable FWHM-based f. It is found that, whether excluding
the pseudobulges or not, the MBH from the Hβ line dispersion in
the mean spectrum (σHβ,mean) has the smallest offset rms
with respect to the MBH-σ* relation. For the total sample
excluding SDSS-RM AGNs, with respect to MBH from σ* or that
from the Hβ line dispersion in the rms spectrum
(σHβ,rms), it is found that we can obtain MBH from the
σHβ,mean with the smallest offset rms of 0.38 or 0.23dex,
respectively. It implies that, with respect to the Hβ FWHM, we
prefer σHβ,mean to calculate MBH from the single-epoch
spectrum. Using the FWHM-based f, we can improve the MBH calculation
from FWHM(Hβ) and the mean f, with a decreased offset rms from
0.52 to 0.39 dex with respect to MBH from σ* for the
subsample of 36 AGNs with σ*. The value of 0.39dex is almost
the same as that from σHβ,mean and the mean f.
