The SLUGGS survey: Globular cluster stellar population trends from weak absorption lines in stacked spectra
Christopher Usher, Duncan A. Forbes, Jean P. Brodie +7
As part of the SLUGGS survey, we stack 1137 Keck DEIMOS spectra of globular clusters from 10 galaxies to study their stellar populations in detail. The stacked spectra have median…
Kinematics and simulations of the stellar stream in the halo of the Umbrella Galaxy
Caroline Foster, Hanni Lux, Aaron J. Romanowsky +9
We study the dynamics of faint stellar substructures around the Umbrella Galaxy, NGC 4651, which hosts a dramatic system of streams and shells formed through the tidal disruption o…
The SLUGGS survey: Exploring the metallicity gradients of nearby early-type galaxies to large radii
Nicola Pastorello, Duncan A. Forbes, Caroline Foster +5
Stellar metallicity gradients in the outer regions of galaxies are a critical tool for disentangling the contributions of in-situ and ex-situ formed stars. In the two-phase galaxy…
The SAGES Legacy Unifying Globulars and GalaxieS Survey (SLUGGS): Sample definition, methods, and initial results
Jean P. Brodie, Aaron J. Romanowsky, Jay Strader +14
We introduce and provide the scientific motivation for a wide-field photometric and spectroscopic chemodynamical survey of nearby early-type galaxies (ETGs) and their globular clus…
The SLUGGS Survey: HST/ACS Mosaic Imaging of the NGC 3115 Globular Cluster System
Zachary G. Jennings, Jay Strader, Aaron J. Romanowsky +6
We present HST/ACS and photometry and half-light radii measurements of 360 globular cluster (GC) candidates around the nearby S0 galaxy NGC 3115. We also includ…
Kinematic transitions and streams in galaxy halos
A. J. Romanowsky, J. A. Arnold, J. P. Brodie +7
The chemo-dynamics of galaxy halos beyond the Local Group may now be mapped out through the use of globular clusters and planetary nebulae as bright tracer objects, along with deep…
