GC systems & SMBHs in spiral gal. III.
Listed in IVOA Registry (Virtual Observatory)
We continue to explore the relationship between the total number of globular clusters (GCs), N_GC_, and the central black hole mass, M_BH_, in spiral galaxies.
Description
We present here results for the Sab galaxies NGC3368, NGC4736 (M94), and NGC4826 (M64), and the Sm galaxy NGC4395. The GC candidate selection is based on the (u*-i') versus (i'-Ks) color-color diagram, and i'-band shape parameters.
We determine the M_BH_ versus NGC correlation for these spirals, plus NGC4258, NGC253, M104, M81, M31, and the Milky Way. We also redetermine the correlation for the elliptical sample in Harris et al., with updated galaxy types from Sahu et al. Additionally, we derive the total stellar galaxy mass, M*, from its two-slope correlation with NGC, and fit M_BH_ versus M* for both spirals and ellipticals. We obtain logM_BH_{prop.to}(1.01+/-0.13)logN_GC_ for ellipticals, and logM_BH_{prop.to}(1.64+/-0.24)logN_GC_ for late-type galaxies (LTGs).

The linear M_BH_ versus N_GC_ correlation in ellipticals could be due to statistical convergence through mergers, unlike the much steeper correlation for LTGs. However, in the M_BH_ versus total stellar mass (M*) parameter space, with M* derived from its correlation with N_GC_, M_BH_{prop.to}(1.48+/-0.18)logM* for ellipticals, and M_BH_{prop.to}(1.21+/-0.16)logM* for LTGs. The observed agreement between ellipticals and LTGs in this parameter space may imply that black holes and galaxies coevolve through calm accretion, active galactic nuclei feedback, and other secular processes.
