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 …

We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

Observations indicate that massive stars in the Galaxy form in regions of very high surface
density, Σ∼ 1 g cm-2. Clusters containing massive stars and globular clusters have a …

We present a grid of radiation transfer models of axisymmetric young stellar objects (YSOs),
covering a wide range of stellar masses (from 0.1 to 50 M☉) and evolutionary stages (from …

Whether or not molecular clouds and embedded cloud fragments are stable against
collapse is of utmost importance for the study of the star formation process. Only" …

Context. Whether the Cygnus X complex consists of one physically connected region of star
formation or of multiple independent regions projected close together on the sky has been …

We investigate massive star formation in turbulent, magnetized, parsec-scale clumps of
molecular clouds including protostellar outflow feedback using three-dimensional numerical …

Context. The formation processes and the evolutionary stages of high-mass stars are poorly
understood compared to low-mass stars. Large-scale surveys are needed to provide an …

We describe a systematic program aimed at identifying and characterizing candidate high-
mass protostellar objects (HMPOs). Our candidate sample consists of 69 objects selected by …

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 …
