Gravitational waves from coalescing massive black holes in young dense clusters [PDF]
, 2006 HST observations reveal that young massive star clusters form in gas-rich environments like the Antenn{\ae} galaxy which will merge in collisional processes to form larger structures.

Massive Young Clusters in Nearby Galaxies [PDF]
Symposium - International Astronomical Union, 2001 We study the size distribution of massive young clusters (MYCs) and of the cavities around them. We discuss the existence of two cluster populations and we find evidences for molecular cloud confinement in the early stages of development.

An HST Study of the Substellar Population of NGC 2024
The Astrophysical Journal, 2023 We performed an HST/WFC3-IR imaging survey of the young stellar cluster NGC 2024 in three filters probing the 1.4 μ m H _2 O absorption feature, characteristic of the population of low-mass and substellar-mass objects down to a few Jupiter masses.

Observational Evidence of the Merging of Filaments and Hub Formation in G083.097+03.270
The Astrophysical Journal, 2023 We uncover a hub–filament system correlated with massive young stellar associations in G083.097+03.270. Diagnosed with simultaneous ^12 CO, ^13 CO, and C ^18 O line observations, the region is found to host two distinct and elongated filaments having ...

Resolved photometry of extragalactic young massive star clusters [PDF]
, 2011 We present colour-magnitude diagrams (CMDs) for a sample of seven young massive clusters in the galaxies NGC 1313, NGC 1569, NGC 1705, NGC 5236 and NGC 7793. The clusters have ages in the range 5-50 million years and masses of 10^5 -10^6 Msun.

Proceedings of the International Astronomical Union, 2007 AbstractOver the past ten years, there has been a revolution in our understanding of massive young stellar clusters in the Galaxy. Initially, there were no known examples having masses >104, yet we now know that there are at least a half dozen such clusters in the Galaxy.

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.

Evidence for the Strong Effect of Gas Removal on the Internal Dynamics of Young Stellar Clusters [PDF]
, 2006 We present detailed luminosity profiles of the young massive clusters M82-F, NGC 1569-A, and NGC 1705-1 which show significant departures from equilibrium (King and EFF) profiles.

THE EVOLUTIONARY TRACKS OF YOUNG MASSIVE STAR CLUSTERS [PDF]
The Astrophysical Journal, 2014 Stars mostly form in groups consisting of a few dozen to several ten thousand members. For 30 years, theoretical models provide a basic concept of how such star clusters form and develop: they originate from the gas and dust of collapsing molecular clouds.

Chemical Abundances of Young Massive Clusters in NGC 1313∗
The Astronomical Journal, 2022 Abstract We analyze spectroscopic observations of five young massive clusters (YMCs) in the barred spiral galaxy NGC 1313 to obtain detailed abundances from their integrated light. Our sample of YMCs was observed with the X-shooter spectrograph on the Very Large Telescope.
