The Radial Velocity Experiment (RAVE): second data release
T. Zwitter, A. Siebert, U. Munari +51
We present the second data release of the Radial Velocity Experiment (RAVE), an ambitious spectroscopic survey to measure radial velocities (RVs) and stellar atmosphere parameters…
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…
Observed Properties of Dark Matter: dynamical studies of dSph galaxies
G Gilmore, M Wilkinson, J Kleyna +4
The Milky Way satellite dwarf spheroidal (dSph) galaxies are the smallest dark matter dominated systems in the universe. We have underway dynamical studies of the dSph to quantify…
The Radial Velocity Experiment (RAVE): first data release
M. Steinmetz, T. Zwitter, A. Siebert +51
We present the first data release of the Radial Velocity Experiment (RAVE), an ambitious spectroscopic survey to measure radial velocities and stellar atmosphere parameters (temper…
Complexity on Small Scales: The Metallicity Distribution of the Carina Dwarf Spheroidal Galaxy
A. Koch, E. K. Grebel, R. F. G. Wyse +5
The Carina dwarf spheroidal (dSph) galaxy is the only galaxy of this type that shows clearly episodic star formation separated by long pauses. Here we present metallicities for 437…
A Cusp Slope -- Central Anisotropy Theorem
J. An, N. W. Evans
For a wide class of self-gravitating systems, we show that if the density is cusped like 1/r^{gamma} near the center, then the limiting value of the anisotropy parameter beta = 1 -…
