The Globular Cluster Migratory Origin of Nuclear Star Clusters [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2014
Nuclear Star Clusters (NSCs) are often present in spiral galaxies as well as resolved Stellar Nuclei (SNi) in elliptical galaxies centres. Ever growing observational data indicate the existence of correlations between the properties of these very dense ...

Globular Star Clusters [PDF]

open access: yesNature, 1888
PHYSICAL aggregations of stars may be broadly divided into “globular” and “irregular” clusters. Although, as might have been expected, the line of demarcation between the two classes is by no means sharply drawn, each has its own marked peculiarities. We shall limit our attention, in the present article, to the first kind.

Formation and Disruption of Globular Star Clusters [PDF]

open access: bronzeSymposium - International Astronomical Union, 2002
In the first part of this article, we review observations of the mass and luminosity functions of young and old star cluster systems. We also review some of the physical processes that may determine the characteristic mass of globular clusters and the form of their mass function.

The Cosmic Evolution of Binary Black Holes in Young, Globular and Nuclear Star Clusters: Rates, Masses, Spins and Mixing Fractions [PDF]

open access: yes, 2021
The growing population of binary black holes (BBHs) observed by gravitational wave detectors is a potential Rosetta stone for understanding their formation channels. Here, we use an upgraded version of our semi-analytic codes fastcluster and cosmoRate to

Multiple Populations in Star Clusters [PDF]

open access: yesUniverse, 2022
We review the multiple population (MP) phenomenon of globular clusters (GCs): i.e., the evidence that GCs typically host groups of stars with different elemental abundances and/or distinct sequences in photometric diagrams.

Mass and Rate of Hierarchical Black Hole Mergers in Young, Globular and Nuclear Star Clusters [PDF]

open access: yesSymmetry, 2020
Hierarchical mergers are one of the distinctive signatures of binary black hole (BBH) formation through dynamical evolution. Here, we present a fast semi-analytic approach to simulate hierarchical mergers in nuclear star clusters (NSCs), globular ...

The GeMS/GSAOI Galactic Globular Cluster Survey (G4CS). II. Characterization of 47 Tuc with Bayesian Statistics

open access: yesThe Astrophysical Journal, 2023
We present a photometric analysis of globular cluster 47 Tuc (NGC 104) using near-IR imaging data from the GeMS/GSAOI Galactic Globular Cluster Survey (G4CS), which is in operation at Gemini-South telescope.
