Intracluster Globular Clusters [PDF]

The Astrophysical Journal, 1995
Globular cluster populations of supergiant elliptical galaxies are known to vary widely, from extremely populous systems like that of UGC 9799, the centrally dominant galaxy in Abell 2052, to globular-cluster-poor galaxies such as NGC 5629 in Abell 2666.

HST Imaging of the Globular Clusters in the Fornax Cluster: NGC 1399 and NGC 1404 [PDF]

, 1997
The Fornax cluster galaxies NGC 1399 and NGC 1404 are ideal for studying the effects of a cluster environment on globular cluster systems. Here we present new optical imaging of these two galaxies from both the Hubble Space Telescope's Wide Field and ...

Globular cluster system erosion and nucleus formation in elliptical galaxies [PDF]

, 1998
The radial distribution of globular clusters in galaxies is always less peaked to the centre than the halo stars'. Extending previous work to a sample of HST globular cluster systems in ellipticals, we evaluate the number of clusters lost to the galactic

Dynamics of the Globular Cluster System Associated with M87 (NGC 4486). II. Analysis [PDF]

, 2001
We present a dynamical analysis of the globular cluster system associated with M87 (= NGC 4486), the cD galaxy near the dynamical center of the Virgo cluster.

Gravitational Radiation from Black Hole Binaries in Globular Clusters [PDF]

, 2001
A populations of stellar mass black hole binaries may exist in globular clusters. The dynamics of globular cluster evolution imply that there may be at most one black hole binary is a globular cluster.

Dynamical Friction in dE Globular Cluster Systems [PDF]

, 2001
The dynamical friction timescale for globular clusters to sink to the center of a dwarf elliptical galaxy (dE) is significantly less than a Hubble time if the halos have King-model or isothermal profiles and the globular clusters formed with the same ...

The Dependence of Globular Cluster Number on Density for Abell Cluster Central Galaxies [PDF]

, 1997
A study of the globular cluster systems of 23 brightest, or central, galaxies in 19 Abell clusters has recently been completed. This Letter presents some of the newly discovered correlations of the globular cluster specific frequency $S_N$ in these ...

FSR584 - a new globular cluster in the Galaxy? [PDF]

, 2007
We investigate the nature of the recently catalogued star cluster candidate FSR584, which is projected in the direction of the molecular cloud W3 and may be the nearest globular cluster to the Sun.

Globular Cluster Population of Hickson Compact Group 22a and 90c

, 2001
We present the first measurement of the globular cluster populations of galaxies in Hickson compact groups, in order to investigate the effect of these high density environments on the formation and evolution of globular cluster systems. Based on V and R

The self-enrichment of galactic halo globular clusters : a clue to their formation ? [PDF]

, 1999
We present a model of globular cluster self-enrichment. In the protogalaxy, cold and dense clouds embedded in the hot protogalactic medium are assumed to be the progenitors of galactic halo globular clusters.
