Young massive clusters (YMCs) are dense aggregates of young stars that form the
fundamental building blocks of galaxies. Several examples exist in the Milky Way Galaxy …

Mean proper motions, space orbits, and velocity dispersion profiles of Galactic globular clusters derived from Gaia DR2 data

H Baumgardt, M Hilker, A Sollima… - Monthly Notices of the …, 2019 - academic.oup.com

clusters and the velocity dispersion profiles of 141 globular clusters based on a combination …

Star clusters in evolving galaxies

F Renaud - New Astronomy Reviews, 2018 - Elsevier
Their ubiquity and extreme densities make star clusters probes of prime importance of
galaxy evolution. Old globular clusters keep imprints of the physical conditions of their …

Very high redshift quasars and the rapid emergence of supermassive black holes

P Kroupa, L Subr, T Jerabkova… - Monthly Notices of the …, 2020 - academic.oup.com
The observation of quasars at very high redshift such as Pōniuā'ena is a challenge for
models of supermassive black hole (SMBH) formation. This work presents a study of SMBH …

FROST-CLUSTERS–I. Hierarchical star cluster assembly boosts intermediate-mass black hole formation

A Rantala, T Naab, N Lahén - Monthly Notices of the Royal …, 2024 - academic.oup.com
Observations and high-resolution hydrodynamical simulations indicate that massive star
clusters assemble hierarchically from subclusters with a universal power-law cluster mass …

Galactic-field initial mass functions of massive stars

P Kroupa, C Weidner - The Astrophysical Journal, 2003 - iopscience.iop.org
Over the past years observations of young and populous star clusters have shown that the
stellar initial mass function (IMF) appears to be an invariant featureless Salpeter power law …

Pre-supernova feedback sets the star cluster mass function to a power law and reduces the cluster formation efficiency

EP Andersson, MM Mac Low, O Agertz… - Astronomy & …, 2024 - aanda.org
Context. The star cluster initial mass function is observed to have an inverse power law
exponent around 2, yet there is no consensus on what determines this distribution, and why …

Probing the role of the galactic environment in the formation of stellar clusters, using M83 as a test bench

A Adamo, JMD Kruijssen, N Bastian… - Monthly Notices of …, 2015 - academic.oup.com
We present a study of the M83 cluster population, covering the disc of the galaxy between
radii of 0.45 and 4.5 kpc. We aim to probe the properties of the cluster population as a …

The GRIFFIN Project—Formation of Star Clusters with Individual Massive Stars in a Simulated Dwarf Galaxy Starburst

N Lahén, T Naab, PH Johansson… - The Astrophysical …, 2020 - iopscience.iop.org
We describe a population of young star clusters (SCs) formed in a hydrodynamical
simulation of a gas-rich dwarf galaxy merger resolved with individual massive stars at …

The maximum stellar mass, star-cluster formation and composite stellar populations

C Weidner, P Kroupa - Monthly Notices of the Royal …, 2006 - academic.oup.com
We demonstrate that the mass of the most massive star in a cluster correlates non-trivially
with the cluster mass. A simple algorithm, according to which a cluster is filled up with stars …
