We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

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 …

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 …

Over the past decade, increasingly robust estimates of the dense molecular gas content in
galaxy populations between redshift z= 0 and the peak of cosmic galaxy/star formation (z∼ …

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 …

We review current understanding of star formation, outlining an overall theoretical framework
and the observations that motivate it. A conception of star formation has emerged in which …

This paper provides an update of our previous scaling relations between galaxy-integrated
molecular gas masses, stellar masses, and star formation rates (SFRs), in the framework of …

We measure the star formation efficiency (SFE), the star formation rate (SFR) per unit of gas,
in 23 nearby galaxies and compare it with expectations from proposed star formation laws …

We present a comprehensive analysis of the relationship between star formation rate
surface density, Σ SFR, and gas surface density, Σ gas, at sub-kpc resolution in a sample of …

Far-infrared and submillimeter wavelength surveys have now established the important role
of dusty, star-forming galaxies (DSFGs) in the assembly of stellar mass and the evolution of …
