THE FLATTENING OF GLOBULAR CLUSTERS [PDF]
The Astronomical Journal, 1983 In the three nearest luminous galaxies, the Milky Way System, the Andromeda Galaxy and NGC 5128 the brightest globular clusters are rounder than the faintest ones. On the other hand (contrary to some previous results) the flattening of individual LMC clusters is found to be independent of their luminosities.

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

Intergalactic Globular Clusters [PDF]
Highlights of Astronomy, 2005 AbstractWe 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. The numbers, colors and luminosities of these objects can place constraints on their origin, which in turn may yield new ...

The youngest globular clusters [PDF]
International Journal of Modern Physics D, 2014 It is likely that all stars are born in clusters, but most clusters are not bound and disperse. None of the many protoclusters in our Galaxy are likely to develop into long-lived bound clusters. The super star clusters (SSCs) seen in starburst galaxies are more massive and compact and have better chances of survival. The birth and early development of

Diffusion and Mixing in Globular Clusters [PDF]
The Astrophysical Journal, 2018 Abstract Collisional relaxation describes the stochastic process with which a self-gravitating system near equilibrium evolves in phase-space due to the fluctuating gravitational field of the system. The characteristic timescale of this process is called the relaxation time. In this paper, we highlight the difference between two measures

The Origin of Globular Clusters [PDF]
Symposium - International Astronomical Union, 1988 The purpose of this article is to review some recent attempts to understand the origin of globular clusters. To put this in perspective, it may help to recall the analogous problem of the origin of galaxies. This splits into two parts. First, given a proto-galaxy with a specified mass and radius, how does it collapse, form stars and settle into a state

Motions of Globular Clusters [PDF]
Symposium - International Astronomical Union, 1995 Absolute proper motions of seven globular clusters have been determined with respect to extragalactic references and with accuracies of ∼ 1 mas/yr. Derived quantities and qualitative implications are described.

Proceedings 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.
