A New Method for Estimating Dark Matter Halo Masses using Globular Cluster Systems
Lee R. Spitler, Duncan A. Forbes
All galaxies are thought to reside within large halos of dark matter, whose properties can only be determined from indirect observations. The formation and assembly of galaxies is…
Mapping the Dark Side with DEIMOS: Globular Clusters, X-ray Gas, and Dark Matter in the NGC 1407 Group
Aaron J. Romanowsky, Jay Strader, Lee R. Spitler +4
NGC 1407 is the central elliptical in a nearby evolved galaxy group apparently destined to become a cluster core. We use the kinematics of globular clusters to probe the dynamics a…
Uniting Old Stellar Systems: From Globular Clusters to Giant Ellipticals
Duncan Forbes, Paul Lasky, Alister Graham +1
Here we examine the relationship between the virial and stellar mass for a range of old stellar systems, from GCs to giant ellipticals, and including such Intermediate Mass Objects…
Extending the baseline: Spitzer Mid-Infrared Photometry of Globular Cluster Systems in the Centaurus A and Sombrero Galaxies
Lee R. Spitler, Duncan A. Forbes, Michael A. Beasley
Spitzer IRAC mid-infrared photometry is presented for the globular cluster (GC) systems of the NGC 5128 ("Centaurus A") and NGC 4594 ("Sombrero") galaxies. Existing optical photome…
The connection between globular cluster systems and their host galaxy and environment: a case study of the isolated elliptical NGC 821
Lee R. Spitler, Duncan A. Forbes, Jay Strader +2
In an effort to probe the globular cluster (GC) system of an isolated elliptical galaxy, a comprehensive analysis of the NGC 821 GC system was performed. New imaging from the WIYN…
HST/ACS Wide-Field Photometry of the Sombrero Galaxy Globular Cluster System
L. R. Spitler, S. S. Larsen, J. Strader +3
A detailed imaging analysis of the globular cluster (GC) system of the Sombrero galaxy (NGC 4594) has been accomplished using a six-image mosaic from the Hubble Space Telescope Adv…
