ACS photometry of newly-discovered globular clusters in the outer halo of M31
A. D. Mackey, A. Huxor, A. M. N. Ferguson +6
We report the first results from deep ACS imaging of ten classical globular clusters in the far outer regions (15 < R_p < 100 kpc) of M31. Eight of the clusters, including two of t…
Draco, a flawless dwarf galaxy
Mathieu Segall, Rodrigo Ibata, Michael Irwin +2
The Draco dwarf spheroidal galaxy (dSph), with its apparent immense mass to light ratio and compact size, holds many clues to the nature of the enigmatic dark matter. Here we prese…
High-z radio starbursts host obscured X-ray AGN
A. M. S. Richards, R. J. Beswick, S. T. Garrington +8
We use Virtual Observatory methods to investigate the association between radio and X-ray emission at high redshifts. Fifty-five of the 92 HDF(N) sources resolved by combining MERL…
A Possible Origin of the Mass-Metallicity Relation of Galaxies
J. Koeppen, C. Weidner, P. Kroupa
Observations show that galaxies follow a mass-metallicity relation over a wide range of masses. One currently favoured explanation is that less massive galaxies are less able to re…
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…
ACS photometry of extended, luminous globular clusters in the outskirts of M31
A. D. Mackey, A. Huxor, A. M. N. Ferguson +6
A new population of extended, luminous globular clusters has recently been discovered in the outskirts of M31. These objects have luminosities typical of classical globular cluster…
