Globular Cluster Metallicity Subpopulations in NGC 4472
Bimodality is a common feature of globular cluster (GC) color distributions in galaxies. Although it is well known that the GC system of the Milky Way is...
Globular Cluster Populations: First Results from S4G Early-type Galaxies
Using 3.6 μm images of 97 early-type galaxies, we develop and verify methodology to measure globular cluster populations from the S4G survey images. We find...
Globular Cluster Populations: Results Including S4G Late-type Galaxies
Using 3.6 and 4.5 μm images of 73 late-type, edge-on galaxies from the S4G survey, we compare the richness of the globular cluster populations of these galaxies...
Globular Cluster Red Giants as a Probe of Horizontal Branch Luminosities
Connecting observational data to recent theoretical prescriptions for the luminosity of RR Lyrae, we present a new estimate of the bolometric magnitude of the...
Globular cluster systems as tracers of environmental effects on Virgo early-type dwarfs
Early-type dwarfs (dEs) are by far the most abundant galaxy population in nearby clusters. Whether these objects are primordial, or the recent end products of...
Globular Cluster Systems in Elliptical Galaxies of Coma
Globular cluster systems of 17 elliptical galaxies have been studied in the Coma Cluster of galaxies. Surface-brightness fluctuations have been used to...
We analyse the globular cluster (GC) systems of a sample of 15 massive, compact early-type galaxies (ETGs), 13 of which have already been identified as good...
Context: .Shells in Elliptical Galaxies are faint, sharp-edged features, believed to provide evidence of a recent (˜ 0.5 - 2 × 109 years ago) merger event. We...
Globular clusters in modified Newtonian dynamics: velocity dispersion profiles from self-consistent models
We test the modified Newtonian dynamics (MOND) theory with the velocity dispersion profiles of Galactic globular clusters populating the outermost region of the...
