Abstract:
Black hole (BH) masses predicted from the MBH-sigma relationship
conflict with predictions from the MBH-L relationship for
high-luminosity galaxies, such as brightest cluster galaxies (BCGs).
The MBH-L relationship predicts that some BCGs may harbor BHs with
MBH approaching 1010M☉ while the MBH-sigma relationship
always predicts MBH<3x109M☉. We argue that the MBH-L
relationship is a plausible description for galaxies of high
luminosity. If the cores in central stellar density are formed by
binary BHs, the inner core cusp radius, rγ, may be an
independent witness of MBH. Using central structural parameters
derived from a large sample of early-type galaxies observed by HST,
we argue that L is superior to sigma as an indicator of rγ.

Note (1): BCG identifications are referred to their hosting Abell clusters;
see Postman & Lauer (1995, Cat. J/ApJ/440/28) for details.
Note (2): Bulge luminosities are given for S0 and spiral galaxies.
Note (3): Profile type as follows:
PL = power-law
IF = intermediate form
C = core
Note (4): The radius at which the negative logarithmic-slope of a galaxy's
surface brightness profile reaches a pre-specified value γ. The
average error is 30%, based on comparison of Nuker parameters to
non-parametric estimates of the same parameters.
