Relativistic Binaries in Globular Clusters [PDF]

open access: yesLiving Reviews in Relativity, 2002
The galactic population of globular clusters are old, dense star systems, with a typical cluster containing $10^4 - 10^6$ stars. As an old population of stars, globular clusters contain many collapsed and degenerate objects.

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. Here we present a dynamical analysis of the photometry and three-dimensional kinematics of omega Cen, 47 Tuc, and M15, by means of

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.

The formation and assembly history of the Milky Way revealed by its globular cluster population [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
We use the age–metallicity distribution of 96 Galactic globular clusters (GCs) to infer the formation and assembly history of the Milky Way (MW), culminating in the reconstruction of its merger tree.

The Relationship between Globular Cluster Mass, Metallicity, and Light-element Abundance Variations [PDF]

open access: yesAstronomical Journal, 2019
We investigate aluminum abundance variations in the stellar populations of globular clusters using both literature measurements of sodium and aluminum and APOGEE measurements of nitrogen and aluminum abundances.

Formation of globular cluster systems: from dwarf galaxies to giants [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
Globular cluster (GC) systems around galaxies of a vast mass range show remarkably simple scaling relations. The combined mass of all GCs is a constant fraction of the total galaxy mass and the mean metallicity and metallicity dispersion of the GC system

The Globular Cluster Systems of Ultra-diffuse Galaxies in the Coma Cluster [PDF]

open access: yesAstrophysical Journal, 2018
Ultra-diffuse galaxies (UDGs) are unusual galaxies with low luminosities, similar to classical dwarf galaxies, but with sizes up to ∼5 larger than expected for their mass.

A detached stellar-mass black hole candidate in the globular cluster NGC 3201 [PDF]

open access: yes, 2018
As part of our massive spectroscopic survey of 25 Galactic globular clusters with MUSE, we performed multiple epoch observations of NGC 3201 with the aim of constraining the binary fraction. In this cluster, we found one curious star at the main-sequence
