On the dark matter profile in Sculptor: Breaking the degeneracy with Virial shape parameters
Thomas Richardson, Malcolm Fairbairn
We present a new method for studying tracers in gravitational systems where higher moments of the line-of-sight velocity distribution are introduced via Virial equations rather tha…

Plan beta: Core or Cusp?
Thomas Richardson, Douglas Spolyar, Matt Lehnert
The inner profile of Dark Matter (DM) halos remains one of the central problems in small-scale cosmology. At present, the problem can not be resolved in dwarf spheroidal galaxies d…

Cores in Classical Dwarf Spheroidal Galaxies? A Dispersion-Kurtosis Jeans Analysis Without Restricted Anisotropy
Thomas Richardson, Malcolm Fairbairn
We attempt to measure the density of dark matter in the two Dwarf Spheroidal Galaxies Fornax and Sculptor using a new method which employs Jeans equations based on both the second…
