The spatial evolution of young massive clusters [PDF]
Context. There are a number of methods that identify stellar sub-structure in star forming regions, but these do not quantify the degree of association of individual stars – something which is required if we are to better understand the mechanisms and ...

Young massive star clusters in M51 [PDF]
A search for young massive star clusters (YMCs) in the nearby face-on spiral galaxy M51 (NGC 5194) has been carried out using UBV CCD images from the prime focus camera on the Lick 3 meter Shane telescope. The YMC population is found to be quite rich with a specific U-band luminosity T_L(U) = 1.4, consistent with the high current star formation rate of

Gravitational waves from coalescing massive black holes in young dense clusters [PDF]
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.

Demographics of Neutron Stars in Young Massive and Open Clusters [PDF]
Star clusters appear to be the ideal environment for the assembly of neutron star–neutron star (NS–NS) and black hole–neutron star (BH–NS) binaries.

Constraining globular cluster formation through studies of young massive clusters – II. A single stellar population young massive cluster in NGC 34 [PDF]
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.

Massive Young Clusters in Nearby Galaxies [PDF]
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.

Gas expulsion and the destruction of massive young clusters [PDF]
We examine the luminosity and dynamical mass estimates for young massive stellar clusters. For many young (<50 Myr) clusters, the luminosity and dynamical mass estimates differ by a significant amount. We explain this as being due to many young clusters being out of virial equilibrium (which is assumed in dynamical mass estimates) because the ...

The M/L ratio of massive young clusters
We point out a strong time-evolution of the mass-to-light conversion factor \eta commonly used to estimate masses of dense star clusters from observed cluster radii and stellar velocity dispersions. We use a gas-dynamical model coupled with the Cambridge

Breaching the Limit: Formation of GW190521-like and IMBH Mergers in Young Massive Clusters [PDF]
The LIGO-Virgo-Kagra Collaboration (LVC) discovered recently GW190521, a gravitational wave (GW) source associated with the merger between two black holes (BHs) with mass 66 and >85 M ⊙.
