A spectroscopic confirmation of the Bootes II dwarf spheroidal
A. Koch, M. I. Wilkinson, J. T. Kleyna +6
We present a new suite of photometric and spectroscopic data for the faint Bootes II dwarf spheroidal galaxy candidate. Our deep photometry, obtained with the INT/WFC, suggests a d…
Stellar kinematics in the remote Leo II dwarf spheroidal galaxy -- Another brick in the wall
A. Koch, J. T. Kleyna, M. I. Wilkinson +5
We present the projected velocity dispersion profile for the remote (d=233kpc) Galactic dwarf spheroidal (dSph) galaxy Leo II, based on 171 discrete stellar radial velocities that…
The Observed properties of Dark Matter on small spatial scales
Gerard Gilmore, Mark I. Wilkinson, Rosemary F. G. Wyse +3
We present a synthesis of recent photometric and kinematic data for several of the most dark-matter dominated galaxies. There is a bimodal distribution in half-light radii, with st…
Stellar kinematics and metallicities in the Leo I dwarf spheroidal galaxy -- wide field implications for galactic evolution
A. Koch, M. I. Wilkinson, J. T. Kleyna +5
We present low-resolution spectroscopy of 120 red giants in the Galactic satellite dwarf spheroidal (dSph) Leo I, obtained with the GeminiN-GMOS and Keck-DEIMOS spectrographs. We f…
