Young accreted globular clusters in the outer halo of M31
A. D. Mackey, A. P. Huxor, A. M. N. Ferguson +6
We report on Gemini/GMOS observations of two newly discovered globular clusters in the outskirts of M31. These objects, PAndAS-7 and PAndAS-8, lie at a galactocentric radius of ~87…
Dynamics in the satellite system of Triangulum: Is AndXXII a dwarf satellite of M33?
S. C. Chapman, L. Widrow, M. L. M. Collins +10
We present results from a spectroscopic survey of the dwarf spheroidal And XXII and the two extended clusters EC1 and EC2. These three objects are candidate satellites of the Trian…
The structure of star clusters in the outer halo of M31
N. R. Tanvir, A. D. Mackey, A. M. N. Ferguson +11
We present a structural analysis of halo star clusters in M31 based on deep Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) imaging. The clusters in our sample span…
