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 well-known M BH −σ sph relation between black hole massand velocity dispersion of the host spheroidal component. We compile published mea-surements of both M BH and σ GC for a sample of 13 systems and find the relationlog(M BH ) = α + βlog(σ GC /200) with α = 8.63 ±0.09 and β = 3.76 ±0.52. We…

The Relation Between Globular Cluster Systems and Supermassive Black Holes in Spiral Galaxies: The Case Study of NGC 4258

We aim to explore the relationship between globular cluster total number, N GC , and central black hole mass, M•, in spiral galaxies, and compare it with that recently reported for ellipticals. We

Spectroscopy of NGC 4258 Globular Cluster Candidates: Membership Confirmation and Kinematics

We present multiobject spectroscopic observations of 23 globular cluster candidates (GCCs) in the prototypical megamaser galaxy NGC 4258, carried out with the Optical System for Imaging and

The effect of bars on the M•-σe relation: offset, scatter and residuals correlations

We analyse a set of collisionless disc galaxy simulations to study the consequences of bar formation and evolution on the M_•-σ_e relation of supermassive black holes (SMBHs). The redistribution of

Dark halo microphysics and massive black hole scaling relations in galaxies

We investigate the black hole (BH) scaling relation in galaxies using a model in which the galaxy halo and central BH are a self-gravitating sphere of dark matter (DM) with an isotropic, adiabatic

A CATALOG OF GLOBULAR CLUSTER SYSTEMS: WHAT DETERMINES THE SIZE OF A GALAXY'S GLOBULAR CLUSTER POPULATION?

We present a catalog of 422 galaxies with published measurements of their globular cluster (GC) populations. Of these, 248 are E galaxies, 93 are S0 galaxies, and 81 are spirals or irregulars. Among

Galaxy bulges and their massive black holes: a review

With references to both key and oft-forgotten pioneering works, this article starts by presenting a review into how we came to believe in the existence of massive black holes at the centres of

Radio timing in a millisecond pulsar – extreme/intermediate mass ratio binary system

Radio timing observations of a millisecond pulsar in orbit around the Galactic centre black hole (BH) or a BH at the centre of globular clusters could answer foundational questions in astrophysics

HIGHLIGHTS OF COMMISSION 37 SCIENCE RESULTS

Abstract It is widely accepted that stars do not form in isolation but result from the fragmentation of molecular clouds, which in turn leads to star cluster formation. Over time, clusters dissolve

The column density distribution of hard X-ray radio galaxies

In order to investigate the role of absorption in AGN with jets, we have studied the column density distribution of a hard X-ray selected sample of radio galaxies, derived from the INTEGRAL/IBIS and

Black holes in the early Universe

This review reports on basic, but critical, questions regarding the cosmological significance of MBHs and investigates how the growth of black holes is linked to that of their host galaxy.

A correlation between central supermassive black holes and the globular cluster systems of early-type galaxies

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 NGC of globular

The black hole mass–stellar velocity dispersion correlation: bulges versus pseudo-bulges

We investigate the correlation between the supermassive black holes (SMBHs) mass (Mbh) and the stellar velocity dispersion ( ) in two types of host galaxies: the early-type bulges (disk galaxies with

Beyond the Bulge: A Fundamental Relation between Supermassive Black Holes and Dark Matter Halos

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

The M-σ and M-L Relations in Galactic Bulges, and Determinations of Their Intrinsic Scatter

We derive improved versions of the relations between supermassive black hole mass (MBH) and host-galaxy bulge velocity dispersion (σ) and luminosity (L; the M–σ and M–L relations), based on 49 MBH

Abstract An updated catalogue of 76 galaxies, with direct measurements of supermassive black-hole mass (M bh) plus, when available, the central velocity dispersion (σ0) of their host bulge is

An Observed Fundamental Plane Relation for Supermassive Black Holes

We study observed correlations between supermassive black hole (BHs) and the properties of their host galaxies and show that the observations define a BH "fundamental plane" (BHFP), of the form MBH ∝

Fundamental Planes and the Barless MBH-σ Relation for Supermassive Black Holes

The residuals about the standard Mbh-σ relation correlate with the effective radius, absolute magnitude, and Sérsic index of the host bulge, giving rise to an apparent black hole “fundamental plane.”
