We review the current knowledge about nuclear star clusters (NSCs), the spectacularly
dense and massive assemblies of stars found at the centers of most galaxies. Recent …

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 the PHANGS-MUSE survey, a programme that uses the MUSE integral field
spectrograph at the ESO VLT to map 19 massive (9.4< log (M⋆/M⊙)< 11.0) nearby (D≲ 20 …

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 …

We measure the velocity dispersion, σ, and surface density, Σ, of the molecular gas in
nearby galaxies from CO spectral line cubes with spatial resolution 45–120 pc, matched to …

We compare the observed turbulent pressure in molecular gas, P turb, to the required
pressure for the interstellar gas to stay in equilibrium in the gravitational potential of a …

ABSTRACT The Spitzer Survey of Stellar Structure in Galaxies (S 4 G) is a deep 3.6 and 4.5
μm imaging survey of 2352 nearby (< 40 Mpc) galaxies. We describe the S 4 G data analysis …

We present kinematic orientations and high-resolution (150 pc) rotation curves for 67 main-
sequence star-forming galaxies surveyed in CO (2–1) emission by PHANGS–ALMA. Our …

Spirals in galaxies have long been thought to be caused by gravitational instability in the
stellar component of the disk, but discerning the precise mechanism had proved elusive …

The chemical abundances of spiral galaxies, as probed by H ii regions across their disks,
are key to understanding the evolution of galaxies over a wide range of environments. We …
