2016ApJ...817...21S Supermassive Black Holes and Their Host Spheroids. II. The Red and Blue Sequence in the M_BH_-M_*,sph_ Diagram Savorgnan, Giulia A. D.; Graham, Alister W.; Marconi, Alessandro; Sani, Eleonora Abstract. In our first paper, we performed a detailed (i.e., bulge, disks, bars, spiral arms, rings, halo, nucleus, etc.) decomposition of 66 galaxies, with directly measured black hole masses, M_BH_, imaged at 3.6 mu {{m}} with Spitzer. Our sample is the largest to date and, for the first time, the decompositions were checked for consistency with the galaxy kinematics. We present correlations between M_BH_ and the host spheroid (and galaxy) luminosity, L_sph_ (and L_gal_), and also stellar mass, {M}_*,{sph_}. While most previous studies have used galaxy samples that were overwhelmingly dominated by high-mass, early-type galaxies, our sample includes 17 spiral galaxies, half of which have {M}_{BH_}\lt {10}^7^ {M}_sun_, and allows us to better investigate the poorly studied low-mass end of the {M}_{BH_}{--}{M}_*,{sph_} correlation. The bulges of early-type galaxies follow {M}_{BH_} is proportional to \{M}_*,{sph_}^1.04+/- 0.10^ and define a tight red sequence with intrinsic scatter {{epsilon}}_({M_{BH_}| {M}_*,{sph_})} = 0.43 +/- 0.06 {dex} and a median {M}_{BH_}/{M}_*,{sph_} ratio of 0.68 +/- 0.04%, i.e., a +/- 2sigma range of 0.1%-5%. At the low-mass end, the bulges of late-type galaxies define a much steeper blue sequence, with {M}_{BH_} is proportional to {M}_*,{sph_}^2-3^ and {M}_{BH_}/{M}_*,{sph_} equal to 0.02% at {M}_{BH_} ~ {10}^6^ {M}_sun_. We additionally report that (1) our Sersic galaxy sample follows {M}_{BH_} is proportional to \{M}_*,{sph_}^1.48+/- 0.20^, a less steep sequence than previously reported; (2) bulges with Sersic index {n}_{sph_}\lt 2, argued by some to be pseudo-bulges, are not offset to lower M_BH_ from the correlation defined by the current bulge sample with {n}_{sph_}\gt 2; and (3) L_sph_ and L_gal_ correlate equally well with M_BH_, in terms of intrinsic scatter, only for early-type galaxies---once reasonable numbers of spiral galaxies are included, the correlation with L_sph_ is better than that with L_gal_.
