Clean Kinematic Samples in Dwarf Spheroidals: An Algorithm for Evaluating Membership and Estimating Distribution Parameters When Contamination is Present
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +2
(abridged) We develop an algorithm for estimating parameters of a distribution sampled with contamination, employing a statistical technique known as ``expectation maximization'' (…
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…
