| Summary: | This study investigates reliability of the black hole mass (MBH) estimation
using broad emission lines in spectra of the Type 1 Active Galactic Nuclei
(AGN) from the Sloan Digital Sky Survey (SDSS). Masses derived from the
broad Hα and Hβ emission lines are compared with the stellar velocity
dispersion (σ*). The results show that the MBH-σ* correlation strengthens in
spectral sub-samples characterized by broader Hβ, red asymmetry in Hβ
profiles, high continuum luminosity, and absence of outflows. These findings
suggest that Hα and Hβ provide more accurate black hole mass estimates for
objects with such spectral properties. |
