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.

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

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 ...

Kinematics in Young Star Clusters and Associations with Gaia DR2 [PDF]
Astrophysical Journal, 2018 The Gaia mission has opened a new window into the internal kinematics of young star clusters at the sub-km s−1 level, with implications for our understanding of how star clusters form and evolve.

Modeling Dense Star Clusters in the Milky Way and Beyond with the CMC Cluster Catalog [PDF]
Astrophysical Journal Supplement Series, 2019 We present a set of 148 independent N-body simulations of globular clusters (GCs) computed using the code CMC (Cluster Monte Carlo). At an age of ∼10–13 Gyr, the resulting models cover nearly the full range of cluster properties exhibited by the Milky ...

Population synthesis of black hole binary mergers from star clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Black hole (BH) binary mergers formed through dynamical interactions in dense star clusters are believed to be one of the main sources of gravitational waves (GWs) for Advanced LIGO and Virgo. Here, we present a fast numerical method for simulating the

Disruption of giant molecular clouds and formation of bound star clusters under the influence of momentum stellar feedback [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Energetic feedback from star clusters plays a pivotal role in shaping the dynamical evolution of giant molecular clouds (GMCs). To study the effects of stellar feedback on the star formation efficiency of the clouds and the dynamical response of ...

Black hole growth through hierarchical black hole mergers in dense star clusters: implications for gravitational wave detections [PDF]
Monthly notices of the Royal Astronomical Society, 2018 In a star cluster with a sufficiently large escape velocity, black holes (BHs) that are produced by BH mergers can be retained, dynamically form new BH binaries, and merge again.

Survivability of planetary systems in young and dense star clusters [PDF]
Astronomy & Astrophysics, 2019 Aims. We perform a simulation using the Astrophysical Multipurpose Software Environment of the Orion Trapezium star cluster in which the evolution of the stars and the dynamics of planetary systems are taken into account. Methods.

A Multi-band Catalog of 10978 Star Clusters, Associations, and Candidates in the Milky Way [PDF]
Astronomical Journal, 2018 We present a catalog of Galactic star clusters, associations and candidates with 10978 entries. This multi-band catalog was constructed over 20 years, starting with visual inspections on the Digital Sky Survey and incremented with the 2MASS, WISE, VVV ...
