Black Holes and Galactic Density Cusps : From Black Hole to Bulge
Morgan Le Delliou, Richard N. Henriksen, Joseph D. Macmillan
Aims. In this paper we continue our study of density cusps that may contain central black holes. Methods. We recall our attempts to use distribution functions with a memory of self…
Black Holes and Galactic Density Cusps Spherically Symmetric Anisotropic Cusps
Morgan Le Delliou, Richard N. Henriksen, Joseph D. Macmillan
Aims: In this paper we study density cusps that may contain central black holes. The actual co-eval self-similar growth would not distinguish between the central object and the sur…
Black holes and Galactic density cusps -- I. Radial orbit cusps and bulges
Morgan Le Delliou, Richard N. Henriksen, Joseph D. Macmillan
In this paper, we study the distribution functions that arise naturally during self-similar radial infall of collisionless matter. Such matter may be thought of either as stars or…
On Universal Halos and the Radial Orbit Instability
Joseph D. MacMillan, Lawrence M. Widrow, Richard N. Henriksen
The radial orbit instability drives dark matter halos toward a universal structure. This conclusion, first noted by Huss, Jain, and Steinmetz, is explored in detail through a serie…
Dynamical Black Hole Growth and the M_{BH}-σRelation
Joseph D. MacMillan, Richard N. Henriksen
This poster discusses a possible explanation for the relationship between the mass of the central supermassive black hole and the velocity dispersion in the bulge of the host galax…
Black Hole Growth in Dark Matter and the M_{bh} - σRelation
Joseph D. MacMillan, Richard N. Henriksen
In this article we consider the growth of seed black holes immersed in dark matter halos. We first investigate the adiabatic growth in various initial distribution functions (isoth…
