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 …

We present and discuss the results of the Herschel Gould Belt survey (HGBS) observations
in an~ 11 deg 2 area of the Aquila molecular cloud complex at d~ 260 pc, imaged with the …

Molecular clouds are supported by turbulence and magnetic fields, but quantifying their
influence on cloud life cycle and star formation efficiency (SFE) remains an open question …

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 …

Within ten nearby (d< 450 pc) Gould belt molecular clouds we evaluate statistically the
relative orientation between the magnetic field projected on the plane of sky, inferred from …

Context. Core condensation is a critical step in the star-formation process, but it is still poorly
characterized observationally. Aims. We have studied the 10 pc-long L1495/B213 complex …

Context. Star formation takes place in giant molecular clouds, resulting in mass-segregated
young stellar clusters composed of Sun-like stars, brown dwarfs, and massive O-type (50 …

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