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 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 formation in the Virgo cluster [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 Metal poor globular clusters (MPGCs) are a unique probe of the early universe, in particular the reionization era. Systems of globular clusters in galaxy clusters are particularly interesting as it is in the progenitors of galaxy clusters that the earliest reionizing sources first formed. Although the exact physical origin of globular clusters is still

THE ABUNDANCES IN THE STELLAR ATMOSPHERES IN THE M13 GLOBULAR CLUSTER
Odessa Astronomical Publications, 2017 The chemical composition of 5 stars' atmospheres in globular cluster M13 and 2 halo stars taken from literature have been computed. A slight excess of O and deficit of Mg have been defined for globular cluster stars.

Dynamical Substructures of Galactic Globular Clusters I. M5 [PDF]
Journal of Astronomy and Space Sciences, 2004 CCD images to study the dynamical substructure of the globular cluster M5. We investigate the radial variation of ellipticities and position angles using the stellar photometry and the IRAF ellipse task.

Extragalactic Globular Clusters in the Near-Infrared: V. IC 4051 and NGC 3311 [PDF]
, 2005 We present the results of combined optical and near-infrared photometry for the globular cluster systems of the giant ellipticals IC 4051 and NGC 3311.

Extragalactic Globular Clusters in the Near-Infrared II. The Globular Clusters Systems of NGC 3115 and NGC 4365 [PDF]
, 2002 We combine near-infrared photometry obtained with the VLT/ISAAC instrument and archival HST/WFPC2 optical images to determine VIK magnitudes and colours of globular clusters in two early-type galaxies, NGC 3115 and NGC 4365.

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
