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 ...

The Role of Binarity and Stellar Rotation in the Split Main Sequence of NGC 2422
The Astrophysical Journal, 2022 In addition to the extended main-sequence turnoffs widely found in young and intermediate-age (∼600 Myr to 2 Gyr old) star clusters, some younger clusters even exhibit split main sequences (MSs).

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 ...

A Catalog of Newly Identified Star Clusters in Gaia DR2 [PDF]
Astrophysical Journal Supplement Series, 2019 We present the Star cluster Hunting Pipeline (SHiP) that can identify star clusters in Gaia second data release (DR2) data and establish a star cluster catalog for the Galactic disk. A friend-of-friend-based cluster finder method is used to identify star

Merging black holes in young star clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Searching for distinctive signatures, which characterize different formation channels of binary black holes (BBHs), is a crucial step towards the interpretation of current and future gravitational wave detections.

Black holes: The next generation—repeated mergers in dense star clusters and their gravitational-wave properties [PDF]
Physical Review D, 2019 When two black holes merge in a dense star cluster, they form a new black hole with a well-defined mass and spin. If that "second-generation" black hole remains in the cluster, it will continue to participate in dynamical encounters, form binaries, and ...

Molecular Gas Properties in Young Stellar Clusters with a Suppressed Star Cluster Wind
The Astrophysical Journal Letters, 2023 In compact and dense star-forming clouds a global star cluster wind could be suppressed. In this case stellar feedback is unable to expel the leftover gas from the cluster. Young massive stars remain embedded in a dense residual gas and stir it by moving
