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∼ …

Stars are among the most fundamental structures of our Universe. They comprise most of the
baryonic and luminous mass of galaxies; synthesize heavy elements; and inject mass …

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 …

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 …

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 …

This paper presents cosmological results based on full-mission Planck observations of
temperature and polarization anisotropies of the cosmic microwave background (CMB) …

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

In this chapter we review recent advances in understanding the roles that magnetic fields
play throughout the star formation process, gained through observations and simulations of …

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 …
