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 …

Partially ionized plasmas are found across the Universe in many different astrophysical
environments. They constitute an essential ingredient of the solar atmosphere, molecular …

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 …

Giant molecular clouds (GMCs) are the primary reservoirs of cold, star-forming molecular
gas in the Milky Way and similar galaxies, and thus any understanding of star formation must …

We report on the filaments that develop self-consistently in a new numerical simulation of
cloud formation by colliding flows. As in previous studies, the forming cloud begins to …

these) and objects dense in our Galaxy can play in our understanding of star and planet
formation as a whole. Comparing the demographics of young massive cluster (YMC) …

Massive stars influence their surroundings through radiation, winds, and supernova
explosions far out of proportion to their small numbers. However, the physical processes that …

We investigate the formation and evolution of giant molecular clouds (GMCs) by the collision
of convergent warm neutral medium (WNM) streams in the interstellar medium, in the …

We investigate the properties of" star-forming regions" in a previously published numerical
simulation of molecular cloud formation out of compressive motions in the warm neutral …

Aims. We aim to identify and characterize cores in the high-mass protocluster W49A,
determine their evolutionary stages, and measure the associated lifetimes. Methods. We …
