The emergence of globular clusters and globular-cluster-like dwarfs. [PDF]
NatureAbstract Globular clusters (GCs) are among the oldest and densest stellar systems in the Universe, yet how they form remains a mystery1. Here we present a suite of cosmological simulations in which both dark-matter-free GCs and dark-matter-rich dwarf galaxies naturally emerge in the Standard Cosmology.

Relativistic Binaries in Globular Clusters [PDF]
Living Reviews in Relativity, 2013 Galactic globular clusters are old, dense star systems typically containing 10^4 – 10^6 stars. As an old population of stars, globular clusters contain many collapsed and degenerate objects. As a dense population of stars, globular clusters are the scene

Internal dynamics of globular clusters [PDF]
Astronomy and Astrophysics Review, 1997 Galactic globular clusters, which are ancient building blocks of our Galaxy, represent a very interesting family of stellar systems in which some fundamental dynamical processes have taken place on time scales shorter than the age of the universe.

ROTATING GLOBULAR CLUSTERS [PDF]
The 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. Here we present a dynamical analysis of the photometry and three-dimensional kinematics of omega Cen, 47 Tuc, and M15, by means of

The Structure of Globular Clusters [PDF]
Symposium - International Astronomical Union, 1986 We report the preliminary results of a CCD surface photometry survey of a large fraction of all known Galactic globular clusters. About 1/5 of all surveyed clusters show a characteristic post-core-collapse (PCC) morphology. The PCC clusters are on average closer to the Galactic center than the King-model-like clusters.

Prospects for Detecting Fast Radio Bursts in the Globular Clusters of Nearby Galaxies
The Astrophysical Journal, 2023 The recent detection of a repeating fast radio burst (FRB) in an old globular cluster in M81 challenges traditional FRB formation mechanisms based on the magnetic activity of young neutron stars formed in core-collapse supernovae.

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.
