Star clusters are fundamental units of stellar feedback and unique tracers of their host
galactic properties. In this review, we will first focus on their constituents, ie detailed insight …

Molecular clouds are a fundamental ingredient of galaxies: they are the channels that
transform the diffuse gas into stars. The detailed process of how they do it is not completely …

We present PHANGS–ALMA, the first survey to map CO J= 2→ 1 line emission at∼ 1''∼ 100
pc spatial resolution from a representative sample of 90 nearby (d≲ 20 Mpc) galaxies that lie …

We present a rich, multiwavelength, multiscale database built around the PHANGS–ALMA
CO (2− 1) survey and ancillary data. We use this database to present the distributions of …

Winds from massive stars have velocities of 1000 km s− 1 or more and produce hot, high-
pressure gas when they shock. We develop a theory for the evolution of bubbles driven by …

The processes of star formation and feedback, regulating the cycle of matter between gas
and stars on the scales of giant molecular clouds (GMCs;∼ 100 pc), play a major role in …

It is a major open question which physical processes stop gas accretion on to giant
molecular clouds (GMCs) and limit the efficiency at which gas is converted into stars. While …

Aims. The complexity of star formation at the physical scale of molecular clouds is not yet
fully understood. We investigate the mechanisms regulating the formation of stars in different …

Molecular clouds are supported by turbulence and magnetic fields, but quantifying their
influence on cloud life cycle and star formation efficiency (SFE) remains an open question …

We use an unprecedented sample of about 23 000 H II regions detected at an average
physical resolution of 67 pc in the PHANGS–MUSE sample to study the extragalactic H II …
