Rotating Globular Clusters [PDF]

open access: yesThe Astrophysical Journal, 2013
Internal rotation is considered to play a major role in the dynamics of some globular clusters. However, in only few cases it has been studied by quantitative application of realistic and physically justified global models.

Intergalactic Globular Clusters [PDF]

open access: yesHighlights of Astronomy, 2003
We confirm and extend our previous detection of a population of intergalactic globular clusters in Abell 1185, and report the first discovery of an intergalactic globular cluster in the nearby Virgo cluster of galaxies.

Globular cluster candidates within the Fornax Cluster: Intracluster globulars? [PDF]

open access: yesAstronomy & Astrophysics, 2003
We present the results of a search for globular clusters in the surroundings of 15 low surface brightness dwarf galaxies belonging to the Fornax Cluster, which was carried out on CCD images obtained with the C and T1 filters of the Washington photometric system.

Globular cluster ages [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
We review two new methods to determine the age of globular clusters (GCs). These two methods are more accurate than the classical isochrone fitting technique. The first method is based on the morphology of the horizontal branch and is independent of the distance modulus of the globular cluster.

Multiple Populations in Star Clusters

open access: yesUniverse, 2022
We review the multiple population (MP) phenomenon of globular clusters (GCs): i.e., the evidence that GCs typically host groups of stars with different elemental abundances and/or distinct sequences in photometric diagrams.

Globular Clusters in Dwarf Galaxies [PDF]

open access: yes, 2005
Data are presently available on the luminosities and half-light radii of 101 globular clusters associated with low-luminosity parent galaxies. The luminosity distribution of globulars embedded in dwarf galaxies having $M_{v} > -16$ is found to differ ...

Modelling Individual Globular Clusters [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
AbstractAstronomers have constructed models of globular clusters for over 100 years. These models mainly fall into two categories: (i) static models, such as King's model and its variants, and (ii) evolutionary models. Most attention has been given to static models, which are used to estimate mass-to-light ratios and mass segregation, and to combine ...

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

open access: yes, 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
