We investigate the origin of the color-magnitude relation (CMR) observed in cluster galaxies by using a combination of a cosmological N-body simulation of a cluster of galaxies and a semi-analytic mod...
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...
Do giant spiral galaxies thwart clusters of young stars?（图）

2010/11/30
Astronomers in Scotland and Germany say simple physics may explain a long-standing paradox: why large clusters of young stars tend to reside in relatively small galaxies and not in giants like the Mil...

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...
ON THE DENSITY AND SURFACE BRIGHTNESS PROFILES IN GLOBULAR STAR CLUSTERS
globular clusters general
2009/2/13
A model of mass distribution, applicable to globular star clusters
and proposed earlier, is reconsidered. It is shown that it can be related to the
well-known Plummer-Schuster formula, and the equat...
