From the Top Down and Back Up Again: Star Cluster Structure from Hierarchical Star Formation [PDF]

, 2018
Young massive star clusters spanning $\sim 10^4 - 10^8 M_\odot$ in mass have been observed to have similar surface brightness profiles. Recent hydrodynamical simulations of star cluster formation have also produced star clusters with this structure.

Gas expulsion versus gas retention: what process dominates in young massive clusters? [PDF]

, 2016
The ability of young stellar clusters to expel or retain the gas left over after a first episode of star formation is a central issue in all models aiming to explain multiple stellar populations and the peculiar light element abundance patterns in ...

Searching for globular cluster-like abundance patterns in young massive clusters - II. Results from the Antennae galaxies [PDF]

, 2017
The presence of multiple populations (MPs) with distinctive light element abundances is a widespread phenomenon in clusters older than 6 Gyr. Clusters with masses, luminosities, and sizes comparable to those of ancient globulars are still forming today ...

Massive stars in young VVV clusters [PDF]

Proceedings of the International Astronomical Union, 2016
The role of massive stars in the Galactic evolution is crucial. During their lifetime these stars change the kinematics around them through stellar winds, affect the formation of new stars, ionise and chemically enrich the media with the final supernova explosion. But the census of both massive stars and their host clusters is still poor.

JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc

The Astrophysical Journal, 2023
Star cluster formation in the early universe and its contribution to reionization remains largely unconstrained to date. Here we present JWST/NIRCam imaging of the most highly magnified galaxy known at z ∼ 6, the Sunrise arc.

On the possible generation of the young massive open clusters Stephenson2 and BDSB122 by Omega Centauri [PDF]

, 2009
A massive objects such as a globular cluster passing through the disk of a galaxy can trigger star formation. We test the hypothesis that the most massive globular cluster in the Galaxy, $\omega$ Centauri, which crossed the disk approximately $24\pm2 ...

The Mass Function of Super Giant Molecular Complexes and Implications for Forming Young Massive Star Clusters in the Antennae (NGC 4038/39)

, 2003
We have used previously published observations of the CO emission from the Antennae (NGC 4038/39) to study the detailed properties of the super giant molecular complexes with the goal of understanding the formation of young massive star clusters.

Gamma ray emission from embedded young massive star clusters unveiled by Fermi-LAT [PDF]

EPJ Web of Conferences
Massive star clusters (SCs) have been proposed as additional contributors to Galactic Cosmic rays (CRs), to overcome the limitations of supernova remnants (SNR) to reach the highest energy end of the Galactic CR spectrum.
