Star Formation in Violent and Normal Evolutionary Phases [PDF]
, 2001 Mergers of massive gas-rich galaxies trigger violent starbursts that - over timescales of $> 100$ Myr and regions $> 10$ kpc - form massive and compact star clusters comparable in mass and radii to Galactic globular clusters.

On the Origin of GW190521-like Events from Repeated Black Hole Mergers in Star Clusters [PDF]
Astrophysical Journal, 2020 LIGO and Virgo have reported the detection of GW190521, from the merger of a binary black hole (BBH) with a total mass around 150 M⊙. While current stellar models limit the mass of any black hole (BH) remnant to about 40–50 M⊙, more massive BHs can be ...

Black Hole Mergers from Hierarchical Triples in Dense Star Clusters [PDF]
Astrophysical Journal, 2020 Hierarchical triples are expected to be produced by the frequent binary-mediated interactions in the cores of globular clusters. In some of these triples, the tertiary companion can drive the inner binary to merger following large eccentricity ...

Missing for 20 yr: MeerKAT Redetects the Elusive Binary Pulsar M30B
The Astrophysical Journal Letters, 2023 PSR J2140−2311B is a 13 ms pulsar discovered in 2001 in a 7.8 hr Green Bank Telescope observation of the core-collapsed globular cluster M30 and predicted to be in a highly eccentric binary orbit.

New Parameters for Star Cluster Dynamics: The Effect of Primordial Binaries and Dark Remnants
The Astrophysical Journal, 2023 By studying the normalized cumulative radial distribution (nCRD) of the stars in the central region of a Monte Carlo-simulated globular cluster, we recently defined three parameters able to pinpoint the stage of internal dynamical evolution reached by ...

Dynamics and Interactions of Binaries and Neutron Stars in Globular Clusters [PDF]
, 1994 We model the dynamics of test binaries in isotropic, multi-mass models of galactic globular clusters. The evolution of binary orbits through the cluster potentials is modeled, including second order diffusion terms, and probabilities for close encounters

The Disruption of Globular Star Clusters in the Galaxy: A Comparative Analysisbetween Fokker-Planck and N-Body Models [PDF]
, 1998 Recent N-body simulations have shown that there is a serious discrepancy between the results of the N-body simulations and the results of Fokker-Planck simulations for the evolution of globular and rich open clusters under the influence of the galactic ...

The Supersonic Project: Star Formation in Early Star Clusters without Dark Matter
The Astrophysical Journal Letters, 2023 The formation mechanism of globular clusters (GCs) has long been debated by astronomers. It was recently proposed that supersonically induced gas objects (SIGOs)–which formed in the early Universe due to the supersonic relative motion of baryons and dark
