2003ApJ...589L..21M The Relation between Black Hole Mass, Bulge Mass, and Near-Infrared Luminosity Marconi, Alessandro; Hunt, Leslie K. Abstract. 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 L_bul_ and BH masses are tightly correlated, and if we consider only those galaxies with a secure BH mass measurement and an accurate L_bul_ (27 objects), the spread of M_BH_-L_bul_ is similar to M_BH_-{sigma}_e_, where {sigma}_e_ is the effective stellar velocity dispersion. We find an intrinsic rms scatter of ~=0.3 dex in logM_BH_. By combining the bulge effective radii R_e_ measured in our analysis with {sigma}_e_, we find a tight linear correlation (rms~=0.25 dex) between M_BH_ and the virial bulge mass (~R_e_{sigma}^2^_e_), with <M_BH_/M_bul_>~0.002. A partial correlation analysis shows that M_BH_ depends on both {sigma}_e_ and R_e_ and that both variables are necessary to drive the correlations between M_BH_ and other bulge properties. Keywords: Black Hole Physics, Galaxies: Bulges, Galaxies: Fundamental Parameters, Galaxies: Nuclei
