The Fundamental Plane (FP) of Black Hole (BH) Activity in galactic nuclei
relates X-ray and radio luminosities to BH mass and accretion rate. However,
there is a large scatter exhibited by the data, which motivated us for a new
variable. We add BH spin as a new variable and estimate the spin dependence of
the jet power and disk luminosity in terms of radio and X-ray luminosities. We
assume the Blandford-Znajek process as the main source of the outflow, and find
that the jet power depends on BH spin stronger than quadratically at moderate
and large spin values. We perform a statistical analysis for 10 AGNs which have
sub-Eddington accretion rates and whose spin values are measured independently,
and find that the spin-dependent relation describes the data significantly
better. This analysis shows not only the spin dependence of the FP relation,
but also implies the Blandford-Znajek process in AGN jets.
