Probing the Nature of the G1 Clump Stellar Overdensity in the Outskirts of M31
Daniel Faria, Rachel A. Johnson, Annette M. N. Ferguson +5
We present deep HST/ACS observations of the G1 clump, a distinct stellar overdensity lying at ~30 kpc along the south-western major axis of M31 close to the G1 globular cluster (Fe…
Exploring Halo Substructure with Giant Stars X. Extended Dark Matter or Tidal Disruption?: The Case for the Leo I Dwarf Spheroidal Galaxy
Sangmo Tony Sohn, S. R. Majewski, R. R. Muñoz +7
We present a wide-field (4.5 deg^2) photometric and spectroscopic survey of the Leo I dwarf spheroidal (dSph) galaxy to explore its extended morphology and dynamics. As in previous…
Exploring Halo Substructure with Giant Stars XI: The Tidal Tails of the Carina Dwarf Spheroidal and the Discovery of Magellanic Cloud Stars in the Carina Foreground
Ricardo R. Munoz, Steven R. Majewski, Simone Zaggia +10
A new large-area Washington M,T_2+DDO51 filter survey of more than 10 deg^2 around the Carina dSph galaxy reveals a spectroscopically confirmed power law radial density "break" pop…
The Effect of Substructure on Mass Estimates of Galaxies
Brian M. Yencho, Kathryn V. Johnston, James S. Bullock +1
Large galaxies are thought to form hierarchically, from the accretion and disruption of many smaller galaxies. Such a scenario should naturally lead to galactic phase-space distrib…
