Abstract:
We derived the black hole fundamental plane relationship between the
1.4GHz radio luminosity (Lr), 0.1-2.4keV X-ray luminosity (LX), and
black hole mass (M) from a uniform broad-line SDSS AGN sample
including both radio-loud and radio-quiet X-ray-emitting sources. We
found in our sample that the fundamental plane relation has a very
weak dependence on the black hole mass, and a tight correlation also
exists between the Eddington-luminosity-scaled X-ray and radio
luminosities for the radio-quiet subsample. In addition, we noticed
that the radio-quiet and radio-loud AGNs have different power-law
slopes in the radio-X-ray nonlinear relationship. The radio-loud
sample displays a slope of 1.39, which seems consistent with the
jet-dominated X-ray model. However, it may also be partly due to the
relativistic beaming effect. For the radio-quiet sample the slope of
the radio-X-ray relationship is about 0.85, which is possibly
consistent with the theoretical prediction from the
accretion-flow-dominated X-ray model. We briefly discuss the reason
why our derived relationship is different from some previous works and
expect the future spectral studies in radio and X-ray bands on
individual sources in our sample to confirm our result.
Description:
Our sample is selected from the X-ray-emitting SDSS AGN catalog
(Anderson et al., 2003, Cat. J/AJ/126/2209) and the FIRST 20cm
radio survey1 (White et al., 1997, See Cat. VIII/71).
