Variations in a Universal Density Profile
John R. Jardel, Karl Gebhardt
Using a newly-developed modeling technique, we present orbit-based dynamical models of the Carina, Draco, Fornax, Sculptor, and Sextans dwarf spheroidal (dSph) galaxies. These mode…
Measuring Dark Matter Profiles Non-Parametrically in Dwarf Spheroidals: An Application to Draco
John R. Jardel, Karl Gebhardt, Maximilian Fabricius +2
We introduce a novel implementation of orbit-based (or Schwarzschild) modeling that allows dark matter density profiles to be calculated non-parametrically in nearby galaxies. Our…
The Dark Matter Density Profile of the Fornax Dwarf
John Jardel, Karl Gebhardt
We construct axisymmetric Schwarzschild models to measure the mass profile of the local group dwarf galaxy Fornax. These models require no assumptions to be made about the orbital…
Orbit-Based Dynamical Models of the Sombrero Galaxy (NGC 4594)
John R. Jardel, Karl Gebhardt, Juntai Shen +6
We present axisymmetric, orbit-based models to study the central black hole, stellar mass-to-light ratio, and dark matter halo of NGC 4594 (M104, the Sombrero Galaxy). For stellar…
Halo density reduction by baryonic settling?
J. R. Jardel, J. A. Sellwood
We test the proposal by El-Zant et al that the dark matter density of halos could be reduced through dynamical friction acting on heavy baryonic clumps in the early stages of galax…
