We review the use of emission lines for understanding galaxy evolution, focusing on
excitation source, metallicity, ionization parameter, ISM pressure, and electron density. We …

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 …

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 …

It remains a major challenge to derive a theory of cloud-scale (pc) star formation and
feedback, describing how galaxies convert gas into stars as a function of the galactic …

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 …

We study the spatially resolved excitation properties of the ionized gas in a sample of 646
galaxies using integral field spectroscopy data from the Sloan Digital Sky Survey IV Mapping …

We identify stellar structures in the PHANGS sample of 74 nearby galaxies and construct
morphological masks of sub-galactic environments based on Spitzer 3.6 μm images. At the …

We compare molecular gas traced by 12 CO (2–1) maps from the HERACLES survey, with
tracers of the recent star formation rate (SFR) across 30 nearby disk galaxies. We …

We investigate the physics driving the cosmic star formation (SF) history using the more than
50 large, cosmological, hydrodynamical simulations that together comprise the …

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 …
