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 …

Recent studies of the nearest star-forming clouds of the Galaxy at submillimeter wavelengths
with the Herschel Space Observatory have provided us with unprecedented images of the …

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 …

The role of turbulence and magnetic fields is studied for star formation in molecular clouds.
We derive and compare six theoretical models for the star formation rate (SFR)—the …

ABSTRACT We present ALMA Band-3/7 observations towards 'the Heart'of a massive hub-
filament system (HFS) SDC335, to investigate its fragmentation and accretion. At a …

Aim. We have investigated the gas organization within the paradigmatic Integral Shape
Filament (ISF) in Orion in order to decipher whether or not all filaments are bundles of fibers …

We present first results from the Herschel Gould Belt survey for the B211/L1495 region in the
Taurus molecular cloud. Thanks to their high sensitivity and dynamic range, the Herschel …

The enormous radiative and mechanical luminosities of massive stars impact a vast range of
scales and processes, from the reionization of the universe, to the evolution of galaxies, to …

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 …

Context. Molecular filaments have received special attention recently thanks to new
observational results on their properties. In particular, our early analysis of filament …
