Galaxy Cluster Mass Estimates in the Presence of Substructure
Evan Tucker, Matthew G. Walker, Mario Mateo +3
We develop and implement a model to analyze the internal kinematics of galaxy clusters that may contain subpopulations of galaxies that do not independently trace the cluster poten…
Tidal Signatures in the Faintest Milky Way Satellites: The Detailed Properties of Leo V, Pisces II and Canes Venatici II
D. J. Sand, J. Strader, B. Willman +5
We present deep wide-field photometry of three recently discovered faint Milky Way satellites: Leo V, Pisces II, and Canes Venatici II. Our main goals are to study the structure an…
A Deeper Look at Leo IV: Star Formation History and Extended Structure
D. J. Sand, A. Seth, E. W. Olszewski +3
We present MMT/Megacam imaging of the Leo~IV dwarf galaxy in order to investigate its structure and star formation history, and to search for signs of association with the recently…
The Star Formation History and Extended Structure of the Hercules Milky Way Satellite
D. J. Sand, E. W. Olszewski, B. Willman +5
We present imaging of the recently discovered Hercules Milky Way satellite and its surrounding regions to study its structure, star formation history and to thoroughly search for s…
A Universal Mass Profile for Dwarf Spheroidal Galaxies?
Matthew G. Walker, Mario Mateo, Edward W. Olszewski +3
(abridged) We apply the Jeans equation to estimate masses for eight of the brightest dSph galaxies. For Fornax we obtain a model-independent constraint on the maximum-circular velo…
