Dynamical models linking BH masses and DM content
Pieter Buyle, Herwig Dejonghe, Maarten Baes
We investigate the relation between the dark matter distribution of galaxies and their central supermassive black holes which is suggested by the v_c-sigma relation. Since early-ty…
The dynamical structure of isotropic spherical galaxies with a central black hole
Maarten Baes, Herwig Dejonghe, Pieter Buyle
We discuss the kinematical structure of a two-parameter family of isotropic models with a central black hole. The family contains the slope of the central density cusp and the rela…
The HI Detection of Low Column Density Clouds and Galaxies
Suzanne M. Linder, Robert F. Minchin, Jonathan I. Davies +5
The HIDEEP survey (Minchin et al. 2003) was done in an attempt to find objects having low inferred neutral hydrogen column densities, yet they found a distribution which was strong…
Observational evidence for a connection between SMBHs and dark matter haloes
Maarten Baes, Herwig Dejonghe, Pieter Buyle +2
We investigate the relation between circular velocity vc and bulge velocity dispersion sigma in spiral galaxies, based on literature data and new spectroscopic observations. We fin…
A search for low surface brightness dwarf galaxies in different environments
S. Roberts, J. Davies, S. Sabatini +6
According to the Cold Dark Matter (CDM) hierarchical clustering theory of galaxy and large scale structure formation, there should be numerous low mass dark matter haloes present i…
A completely analytical family of dynamical models for spherical galaxies and bulges with a central black hole
Maarten Baes, Herwig Dejonghe
We present a family of spherical models for elliptical galaxies and bulges consisting of a stellar component and a central black hole. All models in this family share the same stel…
