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 …

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 …

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 …

Competitive accretion, a process to explain the origin of the initial mass function (IMF),
occurs when stars in a common gravitational potential accrete from a distributed gaseous …

Formation of massive stars by accretion requires a high accretion rate of $\dot {M} _\ast>
10^{-4} M_ {\odot}\,{\rm yr^{-1}} $ to overcome the radiation pressure barrier of the forming …

The relative importance of primordial molecular cloud fragmentation versus large-scale
accretion still remains to be assessed in the context of massive core/star formation. Studying …

ABSTRACT We have observed 37 Infrared Dark Clouds (IRDCs), containing a total of 159
clumps, in high-density molecular tracers at 3 mm using the 22 m ATNF Mopra Telescope …

Star formation is a multi-scale, multi-physics problem ranging from the size scale of
molecular clouds (∼ 10 ∼10 s pc) down to the size scales of dense prestellar cores (∼ 0.1 …

We present the results of dust continuum and molecular line observations of two massive
cluster-forming clumps, NGC 2264-C and NGC 2264-D, including extensive mapping …
