The M-σ and M-L relations in galactic bulges, and determinations of their intrinsic scatter

Abstract:

We derive improved versions of the relations between supermassive black hole mass (M BH) and host-galaxy bulge velocity dispersion (σ) and luminosity (L; the M-σ and M-L relations), based on 49 M BH measurements and 19 upper limits. Particular attention is paid to recovery of the intrinsic scatter (ε0) in both relations. We find log(M BH/M) = α + βlog(σ/200 km s-1) with (α, β, ε0) = (8.12 0.08, 4.24 0.41, 0.44 0.06) for all galaxies and (α, β, ε0) = (8.23 0.08, 3.96 0.42, 0.31 0.06) for ellip...
