We present g and z photometry and size estimates for globular clusters (GCs) in the massive Virgo elliptical NGC 4649 (M60) using a five-pointing Hubble Space Telescope/Advanced Ca…
The SLUGGS Survey: NGC 3115, A Critical Test Case for Metallicity Bimodality in Globular Cluster Systems
Jean P. Brodie, Christopher Usher, Charlie Conroy +4
Due to its proximity (9 Mpc) and the strongly bimodal color distribution of its spectroscopically well-sampled globular cluster (GC) system, the early-type galaxy NGC 3115 provides…
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…
Stellar Kinematics of the Andromeda II Dwarf Spheroidal Galaxy
Nhung Ho, Marla C. Geha, Ricardo R. Munoz +7
We present kinematical profiles and metallicity for the M31 dwarf spheroidal (dSph) satellite galaxy Andromeda II (And II) based on Keck DEIMOS spectroscopy of 531 red giant branch…
Radially Extended Kinematics in the S0 Galaxy NGC 2768 from Planetary Nebulae, Globular Clusters and Starlight
Duncan A. Forbes, Arianna Cortesi, Vincenzo Pota +7
There are only a few tracers available to probe the kinematics of individual early-type galaxies beyond one effective radius. Here we directly compare a sample of planetary nebulae…
