چکیده

We obtain the coefficients of a new fundamental plane for supermassive black holes at the centers of elliptical galaxies, involving measured central black hole mass and photometric parameters which define the light distribution. The galaxies are tightly distributed around this mass fundamental plane, with improvement in the rms residual over those obtained from the MBH − σ and MBH − L relations. This implies a strong multidimensional link between the central massive black hole formation and global photometric properties of elliptical galaxies and provides an improved estimate of black hole mass from galaxy data. Subject headings: black hole physics galaxies: elliptical and lenticular, cD galaxies: nuclei galaxies: evolution galaxies: fundamental parameters galaxies: kinematics and dynamics

Supermassive Black Hole Masses of AGNs with Elliptical Hosts

The recently discovered tight correlation between supermassive black hole mass and central velocity dispersion for both inactive and active galaxies suggests a possibility to estimate the black hole mass from the measured central velocity dispersion. However, for most AGNs it is difficult to measure the central velocity dispersions of their host galaxies directly with the spectroscopic studies....

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 ∝ σ3.0±0.3 R0.43±0.19 e or MBH ∝ M 0.54±0.17 ∗ σ 2.2±0.5, analogous to the FP of elliptical galaxies. The BHFP is preferred over a simple relation between MBH and any of σ, M∗, Mdyn, or Re alone at ...

The Correlation Between Supermassive Black Hole Mass and the Structure of Ellipticals and Bulges

We demonstrate a strong correlation between supermassive black hole (SMBH) mass and the global structure of ellipticals and bulges: more centrally concentrated bulges and ellipticals (higher Sérsic index n) host higher-mass black holes. This correlation is as good as that previously found between SMBH mass and central velocity dispersion, with comparable scatter. In addition, by carefully model...

The Fundamental Scaling Relations of Elliptical Galaxies

We examine the fundamental scaling relations of elliptical galaxies formed through mergers. Using hundreds of simulations to judge the impact of progenitor galaxy properties on the properties of merger remnants, we find that gas dissipation provides an important contribution to tilt in the Fundamental Plane relation. Dissipationless mergers of disks produce remnants that occupy a plane similar ...

Multiple black holes in galactic bulges

We study the number and interaction rates of supermassive black holes in galactic bulges as predicted by hierarchical models of galaxy formation in which the spheroidal components of galaxies are formed by mergers. In bright ellipticals, the number of events that can eject a central supermassive binary black hole is large. Central binaries must therefore merge in less than a Hubble time – other...
