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 …

Modeling galaxy formation in a cosmological context presents one of the greatest
challenges in astrophysics today due to the vast range of scales and numerous physical …

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 …

The physics of star formation and the deposition of mass, momentum and energy into the
interstellar medium by massive stars ('feedback') are the main uncertainties in modern …

The star formation rate (SFR) in galactic disks depends on both the quantity of the available
interstellar medium (ISM) gas and its physical state. Conversely, the ISM's physical state …

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 …

Supernova (SN) explosions deposit prodigious energy and momentum in their
environments, with the former regulating multiphase thermal structure and the latter …

Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

Young stellar associations hold a star formation record that can persist for millions of years,
revealing the progression of star formation long after the dispersal of the natal cloud. To …

Giant molecular clouds (GMCs) and their stellar offspring are the building blocks of galaxies.
The physical characteristics of GMCs and their evolution are tightly connected to galaxy …
