The relation between black hole mass, bulge mass, and near-infrared luminosity.


Abstract (from CDS):

We present new accurate near-infrared (NIR) spheroid (bulge) structural parameters obtained by a two-dimensional image analysis of all galaxies with a direct black hole (BH) mass determination. As expected, NIR bulge luminosities Lbuland BH masses are tightly correlated, and if we consider only those galaxies with a secure BH mass measurement and an accurate Lbul(27 objects), the spread of MBH-Lbulis similar to MBHe, where σe is the effective stellar velocity dispersion. We find an intrinsic rms scatter of ≃0.3 dex in logMBH. By combining the bulge effective radii Remeasured in our analysis with σe, we find a tight linear correlation (rms≃0.25 dex) between MBHand the virial bulge mass (∝Reσ2e), with <MBH/Mbul≳0.002. A partial correlation analysis shows that MBH depends on both σeand Reand that both variables are necessary to drive the correlations between MBHand other bulge properties.
