This review examines the state-of-the-art knowledge of high-mass star and massive cluster
formation, gained from ambitious observational surveys, which acknowledges the multiscale …

Star clusters form in dense, hierarchically collapsing gas clouds. Bulk kinetic energy is
transformed to turbulence with stars forming from cores fed by filaments. In the most compact …

We present a unified description of the scenario of global hierarchical collapse (GHC). GHC
constitutes a flow regime of (non-homologous) collapses within collapses, in which all …

We investigate the presence of hub-filament systems in a large sample of 146 active proto-
clusters, using H13CO+ J= 1-0 molecular line data obtained from the ATOMS survey. We …

We investigate the relation between star formation rate (SFR) and gas surface densities in
Galactic star-forming regions using a sample of young stellar objects (YSOs) and massive …

Star formation rates in the centers of disk galaxies often vastly exceed those at larger radii,
whether measured by the surface density of star formation Σ SFR, by the star formation rate …

Aims. For many years feedback processes generated by OB-stars in molecular clouds,
including expanding ionization fronts, stellar winds, or UV-radiation, have been proposed to …

We present dynamical properties of 294 cores embedded in twelve IRDCs observed as part
of the ASHES Survey. Protostellar cores have higher gas masses, surface densities, column …

Understanding the physical processes that govern the dynamical behavior of the interstellar
medium (ISM) is central to much of modern astronomy and astrophysics. The ISM is the …
