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 …

▪ Abstract Observations of interstellar gas-phase and solid-state species in the 2.4–200 μm
range obtained with the spectrometers on board the Infrared Space Observatory (ISO) are …

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 …

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 …

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

We investigate the physics of gas accretion in young stellar clusters. Accretion in clusters is
a dynamic phenomenon as both the stars and the gas respond to the same gravitational …

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 …

Context. Understanding the formation mechanisms of protoplanetary disks and multiple
systems and also their pristine properties are key questions for modern astrophysics. The …

We present a detailed overview of the science goals and predictions for the Prime-Cam
direct-detection camera–spectrometer being constructed by the CCAT-prime collaboration …
