Young Massive Star Clusters [PDF]
Annual Review of Astronomy and Astrophysics, 2010 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 and the Local Group, but they are particularly abundant in starburst and interacting galaxies.

No evidence of mass segregation in massive young clusters [PDF]
Astronomy and Astrophysics, 2009 Aims. We investigate the validity of the mass segregation indicators commonly used in analysing young stellar clusters. Methods. We simulate observations by constructing synthetic seeing-limited images of a 1000 massive clusters (10^4 Msun) with a standard IMF and a King-density distribution function. Results.

Extremely massive young clusters in NGC 1365 [PDF]
Astronomy & Astrophysics, 2008 In a previous work, three bright MIR/radio sources were discovered in the nuclear region of NGC1365. We here confirm that these sources are young and massive ``embedded'' clusters, and derive their parameters, such as extinction, age and mass. Using ISAAC and VISIR at the VLT we obtained NIR and MIR maps and LR spectra. The dataset is first interpreted

Young and intermediate-age massive star clusters [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010 An overview of our current understanding of the formation and evolution of star clusters is given, with the main emphasis on high-mass clusters. Clusters form deeply embedded within dense clouds of molecular gas. Left-over gas is cleared within a few million years and, depending on the efficiency of star formation, the clusters may

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.

Young massive star clusters: achievements and challenges [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractIn spite of significant recent and ongoing research efforts, most of the early evolution and long-term fate of young massive star clusters remain clouded in uncertainties. Here, I discuss our understanding of the initial conditions of star cluster formation and the importance of initial substructure for the subsequent dynamical-evolution and ...

The early evolution of young massive clusters
Astronomy and Astrophysics, 2023 Context. Young massive clusters provide the opportunity to study the outcome of the star formation process and the early evolution of star clusters. In the first few million years, the (massive) stars dynamically interact, producing runaways and affecting the initial (binary) population. Aims.

Constraining globular cluster formation through studies of young massive clusters - II. A single stellar population young massive cluster in NGC 34 [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 Currently there are two competing scenarios to explain the origin of the stellar population in globular clusters (GCs). The main difference between them is whether or not multiple events of star formation took place within GCs. In this paper we present the star formation history (SFH) of Cluster 1, a massive young cluster in NGC 34 $(\sim10^7\mbox{ M}_\

A cosmic-ray loaded nascent outflow driven by a massive star cluster [PDF]
Nature CommunicationsCosmic rays are widely held to drive outflows from star-forming galaxies and profoundly influence galaxy evolution. Direct evidence for cosmic-ray carrying outflows is however lacking.
