Observations that resolve nearby galaxies into individual regions across multiple phases of
the gas–star formation feedback “matter cycle” have provided a sharp new view of molecular …

Star clusters stand at the intersection of much of modern astrophysics: the ISM, gravitational
dynamics, stellar evolution, and cosmology. Here, we review observations and theoretical …

Giant molecular clouds (GMCs) are the sites of star formation and stellar feedback in
galaxies. Their properties set the initial conditions for star formation and their lifecycles …

Aim. We have investigated the gas organization within the paradigmatic Integral Shape
Filament (ISF) in Orion in order to decipher whether or not all filaments are bundles of fibers …

Star-forming gas clouds are strongly magnetized, and their ionization fractions are high
enough to place them close to the regime of ideal magnetohydrodyamics on all but the …

Context. The gas kinetic temperature (TK) determines the physical and chemical evolution of
the interstellar medium (ISM). However, obtaining reliable TK estimates usually requires …

We present EMPIRE, an IRAM 30 m large program that mapped λ= 3–4 mm dense gas
tracers at∼ 1–2 kpc resolution across the whole star-forming disk of nine nearby massive …

We use hydrodynamical simulations to study the Milky Way's central molecular zone (CMZ).
The simulations include a non-equilibrium chemical network, the gas self-gravity, star …

Aims. We aim to characterize and compare the molecular-line emission of three clouds
whose star-formation rates span one order of magnitude: California, Perseus, and Orion A …

We present a comprehensive suite of high-resolution (parsec-scale), idealized (non-
cosmological) galaxy merger simulations (24 runs, stellar mass ratio∼ 2.5: 1) to investigate …
