Modeling Dense Star Clusters in the Milky Way and beyond with the Cluster Monte Carlo Code [PDF]
Astrophysical Journal Supplement Series, 2021 We describe the public release of the Cluster Monte Carlo (CMC) code, a parallel, star-by-star N-body code for modeling dense star clusters. CMC treats collisional stellar dynamics using Hénon’s method, where the cumulative effect of many two-body ...

Particle acceleration in winds of star clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2021 The origin of cosmic rays in our Galaxy remains a subject of active debate. While supernova remnant (SNR) shocks are often invoked as the sites of acceleration, it is now widely accepted that the difficulties of such sources in reaching PeV energies ...

Populating the Upper Black Hole Mass Gap through Stellar Collisions in Young Star Clusters [PDF]
Astrophysical Journal, 2020 Theoretical modeling of massive stars predicts a gap in the black hole (BH) mass function above ∼40–50 M ⊙ for BHs formed through single star evolution, arising from (pulsational) pair-instability supernovae (PISNe).

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 ...

Intermediate-mass Black Holes from High Massive-star Binary Fractions in Young Star Clusters [PDF]
Astrophysical Journal, 2020 Black holes formed in dense star clusters, where dynamical interactions are frequent, may have fundamentally different properties than those formed through isolated stellar evolution.

Binary black holes in young star clusters: the impact of metallicity [PDF]
, 2020 Young star clusters are the most common birth-place of massive stars and are dynamically active environments. Here, we study the formation of black holes (BHs) and binary black holes (BBHs) in young star clusters, by means of 6000 N-body simulations ...

Star Clusters Near and Far [PDF]
, 2020 Star clusters are fundamental units of stellar feedback and unique tracers of their host galactic properties. In this review, we will first focus on their constituents, i.e.

Dynamics of black hole–neutron star binaries in young star clusters [PDF]
, 2020 Young star clusters are likely the most common birthplace of massive stars across cosmic time and influence the formation of compact binaries in several ways.

Intermediate mass black hole formation in compact young massive star clusters [PDF]
, 2020 Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carried out with Nbody6++GPU of 10 initial conditions for compact $\sim 7 ...

Star Clusters Across Cosmic Time [PDF]
Annual Review of Astronomy and Astrophysics, 2018 Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical models for the formation, evolution, and eventual disruption of star ...
