Bound star clusters observed in a lensed galaxy 460 Myr after the Big Bang. [PDF]

open access: yesNature
The Cosmic Gems arc is among the brightest and highly magnified galaxies observed at redshift z ≈ 10.2 (ref. 1). However, it is an intrinsically ultraviolet faint galaxy, in the range of those now thought to drive the reionization of the Universe2–4 ...

Dynamical Evolution of the Mass Function of Globular Star Clusters [PDF]

open access: bronze, 2001
We present a series of simple, largely analytical models to compute the effects of disruption on the mass function of star clusters. Our calculations include evaporation by two-body relaxation and gravitational shocks and mass loss by stellar evolution ...

On the Rate of Neutron Star Binary Mergers from Globular Clusters [PDF]

open access: bronzeAstrophysical Journal, 2019
The first detection of gravitational waves from a neutron star–neutron star (NS–NS) merger, GW170817, and the increasing number of observations of short gamma-ray bursts have greatly motivated studies of the origins of NS–NS and neutron star–black hole ...

The influence of gas expulsion and initial mass-segregation on the stellar mass-function of globular star clusters [PDF]

open access: yes, 2008
Recently de Marchi, Paresce & Pulone (2007) studied a sample of twenty globular clusters and found that all clusters with high concentrations have steep stellar mass-functions while clusters with low concentration have comparatively shallow mass ...

Signatures of multiple stellar populations in unresolved extragalactic globular/ young massive star clusters [PDF]

open access: yes, 2013
We present an investigation of potential signatures of the formation of multiple stellar populations in recently formed extragalactic star clusters.

MOCCA code for star cluster simulations – IV. A new scenario for intermediate mass black hole formation in globular clusters [PDF]

open access: bronze, 2015
We discuss a new scenario for the formation of intermediate mass black holes (IMBHs) in dense star clusters. In this scenario, IMBHs are formed as a result of dynamical interactions of hard binaries containing a stellar-mass black hole (BH), with other ...

ELVES II: Globular Clusters and Nuclear Star Clusters of Dwarf Galaxies: the Importance of Environment [PDF]

open access: yesAstrophysical Journal, 2021
We present the properties of the globular clusters (GCs) and nuclear star clusters (NSCs) of low-mass (105.5 < M ⋆ < 108.5 M ⊙) early-type satellites of Milky Way–like and small group hosts in the Local Volume (LV) using deep, ground-based data from the ...

Hierarchical black hole mergers in young, globular and nuclear star clusters: the effect of metallicity, spin and cluster properties [PDF]

open access: yes, 2021
We explore hierarchical black hole (BH) mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs), accounting for both original and dynamically assembled binary BHs (BBHs).

Cracking the Relation Between Mass and 1P-star Fraction of Globular Clusters. III. Initial Distributions of In Situ and Ex Situ Clusters

open access: goldThe Astrophysical Journal
Galactic globular clusters consist of two main stellar populations, the pristine (1P) and polluted (2P) stars. The fraction of 1P stars in clusters, F _1P , is a decreasing function of the present-day cluster mass, m _prst . The information about cluster
