The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
Variable Stars in Large Magellanic Cloud Globular Clusters I: NGC 1466
Variable Stars Large Magellanic Cloud Globular Clusters
2011/10/18
This is the first in a series of papers studying the variable stars in Large Magellanic Cloud globular clusters. The primary goal of this series is to better understand how the RR Lyrae stars in Ooste...
A WFC3 study of globular clusters in NGC 4150 - an early-type minor merger
galaxies: star clusters - galaxies: individual: NGC 4150 - galaxies: ellipti-cal and lenticular, cD - galaxies: evolution galaxies: interactions - ultraviolet: galaxies
2011/10/19
We combine near-ultraviolet (NUV; 2250 {\AA}) and optical (U, B, V, I) imaging from the Wide Field Camera 3 (WFC3), on board the Hubble Space Telescope (HST), to study the globular cluster (GC) popula...
Spectra of globular clusters in the Sombrero galaxy: evidence for spectroscopic metallicity bimodality
globular clusters: general galaxies: individual: Sombrero (M104: NGC4594) galaxies: star clusters
2011/9/28
We present a large sample of over 200 integrated-light spectra of confirmed globular clusters (GCs) associated with the Sombrero (M104) galaxy taken with the DEIMOS instrument on the Keck telescope. A...

GLOBULAR CLUSTERS AND PLANETARY NEBULAE KINEMATICS AND X–RAY EMISSION IN THE EARLY–TYPE GALAXY NGC 5128
Galaxies kinematics and dynamics-Galaxies elliptical and lenticular, cD-Galaxies structure-dark matter-Galaxies individual (NGC5128)
2009/2/18
The estimates of the mass of the galaxy NGC 5128 based on the
di erent mass tracers, globular clusters (GCs) and planetary nebulae (PNe), are
presented. These estimates are compared with the estimat...
