Binaries in Globular Clusters [PDF]
Highlights of Astronomy, 1998 Binary stars in a globular cluster (hereafter, GC) may be primordial (i.e. formed along with the cluster), or the result of cluster dynamics. “Dynamical” binaries can result from conservative three-body encounters (e.g. Spitzer, 1987) if a third star can carry away enough kinetic energy to leave two others bound, or from dissipative two-body encounters,

The formation and assembly history of the Milky Way revealed by its globular cluster population [PDF]
Monthly 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 Globular Cluster Systems of Ultra-diffuse Galaxies in the Coma Cluster [PDF]
Astrophysical 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.

Properties of Globular Clusters in Galaxy Clusters: Sensitivity from the Formation and Evolution of Globular Clusters [PDF]
, 2022 We investigate the properties of globular clusters in a galaxy cluster, using the particle tagging method with a semi-analytical approach in a cosmological context. We assume globular clusters form from dark matter halo mergers and their metallicity is assigned based on the stellar mass of the host dark matter halos and the formation redshift of GCs ...

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

Globular cluster star classification: Application to M13 [PDF]
Serbian Astronomical Journal, 2013 Starting from recent determination of Fe, O, Na abundances on a restricted sample (N = 67) of halo and thick disk stars, a natural and well motivated selection criterion is defined for the classification globular cluster stars. An application is

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

Binary black hole mergers from globular clusters: the impact of globular cluster properties [PDF]
Monthly notices of the Royal Astronomical Society, 2018 The dense environment of globular clusters (GCs) can facilitate the formation of binary black holes (BBHs), some of which can merge with gravitational waves within the age of the Universe.

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.
