The possibility that the masses MBH of supermassive black holes (SBHs) correlate with the total gravitational mass of their host galaxy, or the mass MDM of the dark matter halo in which they presumably formed, is investigated using a sample of 16 spiral and 20 elliptical galaxies. The bulge velocity dispersion σc, typically defined within an aperture of size R 0.5 kpc, is found to correlate tightly with the galaxy's circular velocity vc, the latter measured at distances from the Galactic center…

The Black Hole-Dark Matter Halo Connection
We explore the connection between the central supermassive black holes (SMBH) in galaxies and the dark matter halo through the relation between the masses of the SMBHs and the maximum circular
Connecting Dark Matter Halos with the Galaxy Center and the Supermassive Black Hole
Observational studies of nearby galaxies have demonstrated correlations between the mass of the central supermassive black holes (BHs) and properties of the host galaxies, notably the stellar bulge
On the link between central black holes, bar dynamics and dark matter haloes in spiral galaxies
The discovery of a relationship between supermassive black hole (SMBH) mass and spiral arm pitch angle (P) is evidence that SMBHs are tied to the overall secular evolution of a galaxy. The discovery
The bulge-halo connection in galaxies : A physical interpretation of the vc-σ0 relation
We explore the dependence of the ratio of a galaxy's maximum circular velocity, Vc, to its central velocity dispersion, σ0, on morphology or, equivalently, total light concentration. Such a
Direct gravitational imaging of intermediate mass black holes in extragalactic haloes
A galaxy halo may contain a large number of intermediate mass black holes (IMBHs) with masses in the range of 10^{2-6} solar mass. We propose to directly detect these IMBHs by observing multiply
Supermassive black holes and galaxy kinematics
The statistical relation between the masses of supermassive black holes (SMBHs) in disk galaxies and the kinematic properties of their host galaxies is analyzed. Velocity estimates for several

Correlation Between the Total Gravitating Mass of Groups and Clusters and the Supermassive Black Hole Mass of Brightest Galaxies
Supermassive black holes (BHs) residing in the brightest cluster galaxies are over-massive relative to the stellar bulge mass or central stellar velocity dispersion of their host galaxies. As BHs
Why Massive Black Holes are Small in Disk Galxies
A potential mechanism is proposed to account for the fact that supermassive black holes (SMBHs) in disk galaxies appear to be smaller than those in elliptical galaxies in the same luminosity range.


The Correlation between black hole mass and bulge velocity dispersion in hierarchical galaxy formation models
ABSTRA C T Recent work has demonstrated that there is a tight correlation between the mass of a black hole and the velocity dispersion of the bulge of its host galaxy. We show that the model of
The extended rotation curve and the dark matter halo of M33
We present the 21-cm rotation curve of the nearby galaxy M33 out to a galactocentric distance of 16 kpc (13 disk scale-lengths). The rotation curve keeps rising out to the last measured point and
A Fundamental Relation Between Supermassive Black Holes and Their Host Galaxies
The masses of supermassive black holes correlate almost perfectly with the velocity dispersions of their host bulges, Mbh ∝ σα, where α = 4.8 ± 0.5. The relation is much tighter than the relation
