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.

Globular Clusters in the Galactic Bulge [PDF]
Publications of the Astronomical Society of Australia, 2006 AbstractA view of the Galactic bulge by means of their globular clusters is fundamental for a deep understanding of its formation and evolution. Connections between the globular cluster and field star properties in terms of kinematics, orbits, chemical abundances, and ages should shed light on different stellar population components.

The Astrophysical Journal, 2023 In the context of a project aimed at characterizing the dynamical evolution of old globular clusters in the Large Magellanic Cloud, we have secured deep HST/WFC3 images of the massive cluster NGC 1835.

A study of rotating globular clusters. The case of the old, metal-poor globular cluster NGC 4372 [PDF]
, 2014 Context. NGC 4372 is a poorly studied old, very metal-poor globular cluster (GC) located in the inner Milky Way halo. Aims. We present the first in-depth study of the kinematic properties and derive the structural parameters of NGC 4372 based on the fit ...

The Astrophysical JournalGlobular clusters contain vast repositories of metal-poor stars that represent some of the oldest stellar generations in the Universe. The archaeological footprint of early Galactic evolution may be retained in the measurable properties of globular ...

Contribution of stripped nuclear clusters to globular cluster and ultracompact dwarf galaxy populations [PDF]
, 2014 We use the Millennium II cosmological simulation combined with the semi-analytic galaxy formation model of Guo et al. to predict the contribution of galactic nuclei formed by the tidal stripping of nucleated dwarf galaxies to globular cluster (GC) and ...

Globular Cluster Counts around 700 Nearby Galaxies
The Astrophysical JournalEmpirically, the total number (or total mass) of globular clusters (GCs) bound in a single galactic system correlates with the virial mass of the system. The form of this relation and its intrinsic scatter are potentially valuable constraints on theories

MODELING THE FORMATION OF GLOBULAR CLUSTER SYSTEMS IN THE VIRGO CLUSTER [PDF]
, 2014 The mass distribution and chemical composition of globular cluster (GC) systems preserve fossil record of the early stages of galaxy formation. The observed distribution of GC colors within massive early-type galaxies in the ACS Virgo Cluster Survey ...
