Nature and Nurture in Dark Matter Halos
R. N. Henriksen
Cosmological simulations consistently predict specific properties of dark matter halos, but these have not yet led to a physical understanding that is generally accepted. This is e…
Relaxed Dark Matter Halos
R. N. Henriksen
In this paper we reconsider a series expansion for a dark matter distribution function in the spherically symmetric anisotropic limit. We show here that the expansion may be renorm…
Isolated and non-isolated dark matter halos and the NFW profile
R. N. Henriksen
We compare the conclusions reached using the coarse-graining technique employed by Henriksen (2004) for a one degree of freedom (per particle) collisionless system, to those presen…
Coarse-graining the distribution function of cold dark matter II
R. N. Henriksen
We study analytically the coarse and fine-grained distribution function established by the self-similar infall of collisionless matter. We find this function explicitly for isotrop…
Coarse Graining the Distribution Function of Cold Dark Matter
R. N Henriksen, M. Le Delliou
The density profiles established in the self-similar dynamical phase of dark matter haloes recollapse are all close to isothermal. This is steeper than the predictions of some n-bo…
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…
