The Disk Mass Project: breaking the disk-halo degeneracy
Marc A. W. Verheijen, Matthew A. Bershady, Rob A. Swaters +2
Little is known about the content and distribution of dark matter in spiral galaxies. To break the degeneracy in galaxy rotation curve decompositions, which allows a wide range of…
Asymmetric Drift and the Stellar Velocity Ellipsoid
Kyle B. Westfall, Matthew A. Bershady, Marc A. W. Verheijen +2
We present the decomposition of the stellar velocity ellipsoid using stellar velocity dispersions within a 40 deg wedge about the major-axis (sigma_maj), the epicycle approximation…
Exploring Halo Substructure with Giant Stars VIII: The Extended Structure of the Sculptor Dwarf Spheroidal Galaxy
Kyle B. Westfall, Steven R. Majewski, James C. Ostheimer +4
(Abridged) We explore the spatial distribution of stars in the Sculptor dwarf spheroidal (dSph) galaxy over an area of 7.82 deg^2. We identify red giant branch (RGB) starts via Was…
