Star clusters across cosmic time

MR Krumholz, CF McKee… - Annual Review of …, 2019 - annualreviews.org
Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational

Binary black holes in young star clusters: the impact of metallicity

UN Di Carlo, M Mapelli, N Giacobbo… - Monthly Notices of …, 2020 - academic.oup.com

active environments. Here, we study the formation of black holes (BHs) and binary black …

Extended stellar systems in the solar neighborhood-V. Discovery of coronae of nearby star clusters

S Meingast, J Alves, A Rottensteiner - Astronomy & Astrophysics, 2021 - aanda.org
We present a novel view on the morphology and dynamical state of ten prominent, nearby

Radiation hydrodynamics simulations of massive star cluster formation in giant molecular clouds

H Fukushima, H Yajima - Monthly Notices of the Royal …, 2021 - academic.oup.com
By performing 3D radiation hydrodynamics simulations, we study the formation of young
massive star clusters (YMCs; M*> 104 M⊙) in clouds with the surface density ranging from …

Star cluster formation and survival in the first galaxies

Different fates of young star clusters after gas expulsion

X Pang, Y Li, SY Tang, M Pasquato… - The Astrophysical …, 2020 - iopscience.iop.org
We identify structures of the young star cluster NGC 2232 in the solar neighborhood (323.0
pc) and a newly discovered star cluster, LP 2439 (289.1 pc). Member candidates are …

warpfield 2.0: feedback-regulated minimum star formation efficiencies of giant molecular clouds

D Rahner, EW Pellegrini, SCO Glover… - Monthly Notices of the …, 2019 - academic.oup.com
Star formation is an inefficient process and in general only a small fraction of the gas in a
giant molecular cloud (GMC) is turned into stars. This is partly due to the negative effect of …

Stellar-mass black holes in young massive and open stellar clusters–V. comparisons with LIGO-Virgo merger rate densities

S Banerjee - Monthly Notices of the Royal Astronomical Society, 2021 - academic.oup.com
ABSTRACT I study the contribution of young massive star clusters (YMCs) and open star
clusters (OCs) to the present day, intrinsic merger rate density of dynamically assembled …

Realistic modelling of wind and supernovae shocks in star clusters: addressing 22Ne/20Ne and other problems in Galactic cosmic rays

S Gupta, BB Nath, P Sharma… - Monthly Notices of the …, 2020 - academic.oup.com
