Massive Black Holes in Dwarf Spheroidal Galaxy Haloes?
Shoko Jin, Jeremiah P. Ostriker, Mark I. Wilkinson
It is now established that several of the Local Group dwarf Spheroidal galaxies (dSphs) have large mass-to-light ratios. We consider the possibility that the dark matter in the hal…
Mapping the Remote Milky Way Halo using BHB stars at 70 < r < 130 kpc
L. Clewley, S. J. Warren, P. C. Hewett +2
We increase the number of remote halo tracers by using blue horizontal branch (BHB) stars out to Galactocentric distances of 130 kpc. We use SDSS EDR photometry and the VLT to dete…
Core radius evolution of star clusters
Mark I. Wilkinson, Jarrod R. Hurley, A. Dougal Mackey +2
We use N-body simulations of star clusters to investigate the possible dynamical origins of the observed spread in core radius among intermediate-age and old star clusters in the L…
A Dynamical Fossil in the Ursa Minor Dwarf Spheroidal Galaxy
Jan T. Kleyna, Mark I. Wilkinson, Gerard Gilmore +1
The nearby Ursa Minor dwarf spheroidal (UMi dSph) is one of the most dark matter dominated galaxies known, with a central mass to light ratio roughly equal to 70. Somewhat anomalou…
