Disk-Jet Connection in Active Supermassive Black Holes in the Standard Accretion Disk Regime

Understand

We study the disk-jet connection in supermassive black holes by investigating the properties of their optical and radio emissions utilizing the SDSS-DR7 and the NVSS catalogs.

• Our sample contains 7017 radio-loud quasars with detection both at 1.4~GHz and SDSS optical spectrum.
• Using this radio-loud quasar sample, we investigate the correlation among the jet power ($P_{\rm jet}$), the bolometric disk luminosity ($L_{\rm disk}$), and the black hole mass ($M_{\rm BH}$) in the standard accretion disk regime.
• We find that the jet powers correlate with the bolometric disk luminosities as $\log P_{\rm jet} = (0.96\pm0.012)\log L_{\rm disk} + (0.79 \pm 0.55)$.
