− σ ∗ relation for normal galaxies ?

In order to examine the relationship between the black hole mass MBH and stellar velocity dispersion σ∗ in radio-loud active galactic nuclei (AGNs), we study two effects which may cause the uncertainty of black hole mass estimates for radio-loud AGNs: the relativistic beaming effect on the observed optical continuum radiation and the orientation effect on broad emission line width. After correcting these two effects in black hole mass calculations, we re-examine the MBH − σ[OIII] relation for a sample of radio-loud and radio-quiet AGNs compiled from the literatures, and find the MBH − σ[OIII] relation in radio-loud AGNs still deviate from that in nearby normal galaxies and radio-quiet AGNs. We also find there is no significant correlation between radio jet power and narrow [OIII] line width, indicating no strong interaction between radio jet and narrow line region. The deviation from MBH − σ∗ relation in radio-loud AGNs may be intrinsic, or the [OIII] line width is not a good indicator of σ∗ for radio-loud AGNs.
