Unification of the fundamental plane and Super Massive Black Hole Masses
van den Bosch, Remco C. E.
Abstract. According to the virial theorem, all gravitational systems in
equilibrium sit on a plane in the threedimensional parameter space
defined by their mass, size, and second moment of the velocity tensor.
While these quantities cannot be directly observed, there are suitable
proxies: the luminosity L_ k_, halflight radius R_ e_, and dispersion
{sigma}_e_. These proxies indeed lie on a very tight fundamental plane
(FP). How do the black holes (BHs) in the centers of galaxies relate to
the FP? Their masses are known to exhibit no strong correlation with total
galaxy mass, but they do correlate weakly with bulge mass (when present),
and extremely well with the velocity dispersion through the {M}_{bullet}_
is proportional to {sigma}_e_^5.4^ relation. These facts together imply
that a tight plane must also exist defined by BH mass, total galaxy mass,
and size. Here, I show that this is indeed the case using a heterogeneous
set of 230 BHs. The sample includes BHs from zero to 10 billion solar
masses and host galaxies ranging from low surface brightness dwarfs,
through bulgeless disks, to brightest cluster galaxies. The resulting
BHsizeluminosity relation {M}_{bullet}_ is proportional to
{({L}_k_/{R}_e_)}^3.8^ has the same amount of scatter as the
M_blackhole_sigma relation and is aligned with the galaxy FP, such that
it is just a reprojection of {sigma}_e_. The inferred BHsizemass
relation is {M}_{bullet}_ is proportional to {({M}_\star_/{R}_e_)}^2.9^.
These relationships are universal and extend to galaxies without bulges.
This implies that the BH Is primarily correlated with its global velocity
dispersion and not with the properties of the bulge. I show that the
classical bulgemass relation is a projection of the M_blackhole_sigma
relation. When the velocity dispersion cannot be measured (at high z or
low dispersions), the BHsizemass relation should be used as a proxy for
BH mass in favor of just galaxy or bulge mass.
