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.

Multiple Populations in Star Clusters
Universe, 2022 We review the multiple population (MP) phenomenon of globular clusters (GCs): i.e., the evidence that GCs typically host groups of stars with different elemental abundances and/or distinct sequences in photometric diagrams. Most Galactic and extragalactic clusters exhibit internal variations of He, C, N, O, Na, and Al.

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 ...

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.

, 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

First Evidence of Multi-iron Subpopulations in the Bulge Fossil Fragment Candidate Liller 1
The Astrophysical Journal, 2023 In the context of a project aimed at characterizing the properties of the so-called Bulge Fossil Fragments (the fossil remnants of the bulge formation epoch), here we present the first determination of the metallicity distribution of Liller 1.

Ionizing the intergalactic medium by star clusters: the first empirical evidence [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present a VLT/X-Shooter spectroscopy of the Lyman continuum (LyC) emitting galaxy Ion2 at z = 3.2121 and compare it to that of the recently discovered strongly lensed LyC emitter at z = 2.37, known as the Sunburst arc. Three main results emerge from
