The SLUGGS Survey: Wide-field Stellar Kinematics of Early-type Galaxies
Jacob A. Arnold, Aaron J. Romanowsky, Jean P. Brodie +10
We present stellar kinematics of 22 nearby early-type galaxies (ETGs), based on two-dimensional (2D) absorption line stellar spectroscopy out to ~2-4 R_e (effective radii), as part…
The SLUGGS Survey: Wide Field Imaging of the Globular Cluster System of NGC 4278
Christopher Usher, Duncan A. Forbes, Lee R. Spitler +4
We use multi-pointing HST ACS and wide field Subaru Suprime-Cam imaging to study the globular cluster system of the L* elliptical galaxy NGC 4278. We have also obtained a handful o…
The Densest Galaxy
Jay Strader, Anil Seth, Duncan Forbes +8
We report the discovery of a remarkable ultra-compact dwarf galaxy around the massive Virgo elliptical galaxy NGC 4649 (M60), which we term M60-UCD1. With a dynamical mass of 2.0 x…
Filling the gap: a new class of old star cluster?
Duncan Forbes, Vincenzo Pota, Christopher Usher +5
It is not understood whether long-lived star clusters possess a continuous range of sizes and masses (and hence densities), or if rather, they should be considered as distinct type…
The SLUGGS Survey: Kinematics for over 2500 Globular Clusters in Twelve Early-type Galaxies
Vincenzo Pota, Duncan A. Forbes, Aaron J. Romanowsky +10
We present a spectro-photometric survey of 2522 extragalactic globular clusters (GCs) around twelve early-type galaxies, nine of which have not been published previously. Combining…
The SLUGGS Survey: Calcium Triplet-based Spectroscopic Metallicities for Over 900 Globular Clusters
Christopher Usher, Duncan A. Forbes, Jean P. Brodie +6
Although the colour distribution of globular clusters in massive galaxies is well known to be bimodal, the spectroscopic metallicity distribution has been measured in only a few ga…
