Velocity Dispersion Profiles of Seven Dwarf Spheroidal Galaxies
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +4
We present stellar velocity dispersion profiles for seven Milky Way dwarf spheroidal (dSph) satellite galaxies. We have measured 8394 line-of-sight velocities (+/- 2.5 km/s) for 68…
A Kiefer--Wolfowitz comparison theorem for Wicksell's problem
Xiao Wang, Michael Woodroofe
We extend the isotonic analysis for Wicksell's problem to estimate a regression function, which is motivated by the problem of estimating dark matter distribution in astronomy. The…
Internal Kinematics of the Fornax Dwarf Spheroidal Galaxy
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +3
We present new radial velocity results for 176 stars in the Fornax dwarf spheroidal galaxy, of which at least 156 are probable Fornax members. We combine with previously published…
Estimating Dark Matter Distributions
Xiao Wang, Michael Woodroofe, Matthew G. Walker +2
Thanks to instrumental advances, new, very large kinematic datasets for nearby dwarf spheroidal (dSph) galaxies are on the horizon. A key aim of these datasets is to help determine…
