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 …

Giant molecular clouds (GMCs) and their stellar offspring are the building blocks of galaxies.
The physical characteristics of GMCs and their evolution are tightly connected to galaxy …

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 …

Giant molecular clouds (GMCs) are the sites of star formation and stellar feedback in
galaxies. Their properties set the initial conditions for star formation and their lifecycles …

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 …

Star formation is a fundamental process for galactic evolution. One issue over the last
several decades has been determining whether star formation is induced by external …

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

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 …

We address the problem of the origin of massive stars, namely the origin, path, and
timescale of the mass flows that create them. Based on extensive numerical simulations, we …

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 …
