2016ApJ...830..117M The Local Black Hole Mass Function Derived from the MBH-P and the MBH-n Relations Mutlu-Pakdil, Burcin; Seigar, Marc S.; Davis, Benjamin L. Abstract. We present a determination of the supermassive black hole (SMBH) mass function for early- and late-type galaxies in the nearby universe (z < 0.0057), established from a volume-limited sample consisting of a statistically complete collection of the brightest spiral galaxies in the southern hemisphere. The sample is defined by limiting luminosity (redshift-independent) distance, D_ L_ = 25.4 Mpc, and a limiting absolute B-band magnitude, {{M}}_B_=-19.12. These limits define a sample of 140 spiral, 30 elliptical (E), and 38 lenticular (S0) galaxies. We established the Sersic index distribution for early-type (E/S0) galaxies in our sample. Davis et al. established the pitch angle distribution for their sample, which is identical to our late-type (spiral) galaxy sample. We then used the pitch angle and the Sersic index distributions in order to estimate the SMBH mass function for our volume-limited sample. The observational simplicity of our approach relies on the empirical relation between the mass of the central SMBH and the Sersic index for an early-type galaxy or the logarithmic spiral-arm pitch angle for a spiral galaxy. Our SMBH mass function agrees well at the high-mass end with previous values in the literature. At the low-mass end, although inconsistencies exist in previous works that still need to be resolved, our work is more in line with expectations based on modeling of black hole evolution. Key words: galaxies: elliptical and lenticular, cD, galaxies: fundamental parameters, galaxies: nuclei, galaxies: spiral, galaxies: structure
