Description
We present evidence for a strong correlation between the concentration
of bulges and the mass of their central supermassive black hole
(Mbh)-more concentrated bulges have more massive black holes.
Using Cre(1/3) from Trujillo, Graham, & Caon
as a measure of bulge concentration, we find that
log(Mbh/Msolar)=6.81(+/-
0.95)Cre(1/3)+5.03+/-0.41. This correlation is
shown to be marginally stronger (Spearman's rs=0.91) than the
relationship between the logarithm of the stellar velocity dispersion
and logMbh (Spearman's rs=0.86) and has comparable
or less scatter (0.31 dex in logMbh, which decreases to 0.19
dex when we use only those galaxies whose supermassive black hole radii
of influence are resolved and we remove one well-understood outlying
data point).
