To Be or Not to Be: Alicante-8, a Cluster or Not?
Recent surveys have uncovered new young massive clusters that host dozens of red supergiants (RSGs) near the inner Galaxy. However, many of them have still not been fully studied. Using Very Large Telescope/X-shooter near-infrared spectra, we present the

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

A high fraction of Be stars in young massive clusters: evidence for a large population of near-critically rotating stars [PDF]
Recent photometric analysis of the colour-magnitude diagrams (CMDs) of young massive clusters (YMCs) have found evidence for splitting in the main sequence and extended main sequence turn-offs, both of which have been suggested to be caused by stellar ...

Mrk 71 is a low-metallicity ( Z = 0.16 Z _☉ ) starburst region in the local dwarf galaxy NGC 2366, hosting two super star clusters (SSCs A and B), and it is recognized as a Green Pea (GP) analog with SSC A responsible for the GP properties.

Massive White Dwarfs in Young Star Clusters [PDF]
Abstract We have carried out a search for massive white dwarfs (WDs) in the direction of young open star clusters using the Gaia DR2 database. The aim of this survey was (1) to provide robust data for new and previously known high-mass WDs regarding cluster membership, (2) to highlight WDs previously included in the initial final mass ...

Comparing Young Massive Clusters and their Progenitor Clouds in the Milky Way [PDF]
Young massive clusters (YMCs) have central stellar mass surface densities exceeding $10^{4} M_{\odot} pc^{-2}$. It is currently unknown whether the stars formed at such high (proto)stellar densities.

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

Stellar-mass black holes in young massive and open stellar clusters – V. comparisons with LIGO-Virgo merger rate densities [PDF]
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 binary black holes (BBHs).

Universal Upper End of the Stellar Initial Mass Function in the Young and Compact LEGUS Clusters
We investigate the variation in the upper end of the stellar initial mass function (uIMF) in 375 young and compact star clusters in five nearby galaxies within ∼5 Mpc. All the young stellar clusters (YSCs) in the sample have ages ≲ 4 Myr and masses above
