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 ...

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.

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

Proceedings of the International Astronomical Union, 2009 AbstractThe centers of most galaxies in the local Universe are occupied by compact, barely resolved sources. Based on their structural properties, position in the Fundamental Plane, and integrated spectra, these sources clearly have a stellar origin. They are therefore called ‘nuclear star clusters’ (NCs) or ‘stellar nuclei’.

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 ...

Surviving infant mortality in the hierarchical merging scenario [PDF]
, 2011 We examine the effects of gas expulsion on initially sub-structured and out-of-equilibrium star clusters. We perform $N$-body simulations of the evolution of star clusters in a static background potential before removing that potential to model gas ...

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.

, 2010 It is generally assumed that a large fraction of stars are initially born in clusters. However, a large fraction of these disrupt on short timescales and the stars end up belonging to the field. Understanding this process is of paramount importance if we

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.
