Over the past decade, increasingly robust estimates of the dense molecular gas content in
galaxy populations between redshift z= 0 and the peak of cosmic galaxy/star formation (z∼ …

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 …

Icy grain mantles are the main reservoir of the volatile elements that link chemical processes
in dark, interstellar clouds with the formation of planets and the composition of their …

Context. In the past few years, there has been a rise in the detection of streamers,
asymmetric flows of material directed toward the protostellar disk with material from outside …

Hydrodynamical cosmological simulations are increasing their level of realism by
considering more physical processes and having greater resolution or larger statistics …

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 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 …

In the past twenty years, the reconnaissance of 12CO and 13CO emission in the Milky Way
by single-dish millimeter-wave telescopes has expanded our view and understanding of …

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 …

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 …
