Elliptical, lenticular, and early-type spiral galaxies show a remarkably tight power-law correlation between the mass M • of their central supermassive black hole (SMBH) and the number N GC of globular clusters (GCs): M • = m •/ × N 1.08±0.04 GC with m •/ = 1.7 × 105 M ☉. Thus, to a good approximation the SMBH mass is the same as the total mass of the GCs. Based on a limited sample of 13 galaxies, this relation appears to be a better predictor of SMBH mass (rms scatter 0.2 dex) than the M…

Exploring the correlations between globular cluster populations and supermassive black holes in giant galaxies
This paper presents an analysis of the correlation between the number of globular clusters (N GC) in giant galaxies and the mass of the galaxies' central supermassive black hole (M SMBH). I construct
The globular cluster/central black hole connection in galaxies
We explore the relation between the total globular population in a galaxy (NGC) and the mass of its central black hole (M•). Using a sample of 33 galaxies, twice as large as the original sample
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
Globular clusters and supermassive black holes in galaxies: further analysis and a larger sample
We explore several correlations between various large-scale galaxy properties, particularly total globular cluster population (N_GCS), the central black hole mass (M_BH), velocity dispersion
MBHrelation between SMBHs and the velocity dispersion of globular cluster systems
ABSTRACT We find evidence that the mass M BH of central supermassive black holes (SMBHs)correlates with the velocity dispersion σ GC of globular cluster systems of their hostgalaxies. This extends the
Globular Cluster Systems and X-Ray Atmospheres in Galaxies
We compare the empirical relationships between the mass of a galaxy's globular system M_GCS, the gas mass in the hot X-ray atmosphere M_X within a fiducial radius of 5 r_e, the total gravitational
The influence of mergers and ram-pressure stripping on black hole-bulge correlations
We analyse the scatter in the correlation between super-massive black hole (SMBH) mass and bulge stellar mass of the host galaxy, and infer that it cannot be accounted for by mergers alone. The

Context. Thanks to the improved angular resolution of modern telescopes and kinematic models, the existence of supermassive black holes (SMBHs) in the inner part of galaxies, regardless their
A simple way to classify supermassive black holes
We propose a classification of supermassive black holes (SMBHs) based on their efficiency in the conversion of infalling mass in emitted radiation. We use a theoretical model that assumes a
We analyze the relation between the mass of the central supermassive black hole (M{sub BH}) and the number of globular clusters (N{sub GC}) in elliptical galaxies and bulges as a ramification of the


A Relationship between Nuclear Black Hole Mass and Galaxy Velocity Dispersion
We describe a correlation between the mass Mbh of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion σe within the half-light radius. The result is based on a
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
The Supermassive Black Hole and Dark Matter Halo of NGC 4649 (M60)
We apply the axisymmetric orbit superposition modeling to estimate the mass of the supermassive black hole (BH) and dark matter (DM) halo profile of NGC 4649. We have included data sets from the

We construct dynamical models for a sample of 36 nearby galaxies with Hubble Space Telescope (HST) photometry and ground-based kinematics. The models assume that each galaxy is axisymmetric, with a

Star-forming galaxies at z∼ 2 and the formation of the metal-rich globular cluster population
We examine whether the super star-forming (super-SF) clumps (R∼ 1–3 kpc; M∼ 108– 109.5 M⊙) now known to be a key component of star-forming galaxies at z∼ 2 could be the formation sites of the locally
