abstract
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 gas contents and star formation rates are discussed, and updated prescriptions for calculating star formation rates are provided. We review relations between star formation and gas on scales ranging from entire galaxies to individual molecular clouds.

Binary interactions and cluster dynamics boost PISN rates by up to 3x versus single stars, enabling constraints on stellar-wind mass loss and galaxy metallicity distributions.
JWST/MIRI detects [Ne V] 14.3 micron emission from O-star winds in 5 of 22 observed stars, enabling wind speed and mass-loss rate estimates even in weak-wind regimes.
JWST MIRI observations of 634 galaxies at 0.2<z<2 yield IR luminosity functions with faint-end slope α≈0.147, implying lower dust-obscured SFRD than previous ALMA/Herschel/Spitzer studies.
Introduces a semi-deterministic star sampling method in simulations that derives the instantaneous IMF from current cluster mass using reservoir particles and on-the-fly cluster finding.
RUBIES JWST sample shows U increases with redshift and sSFR, decreases with mass, rising by a factor of ~4 from z=2 to z=6 at fixed mass and sSFR, with 0.3 dex systematic uncertainty from photoionization model range.
Confirmation of 77 new heavily reddened quasars at 1.5 < z < 3.9 with high luminosities and extinctions, showing they are deficient in hot and warm dust relative to blue quasars and supporting a blow-out feedback phase.
JWST observations identify all massive young embedded star clusters in the Antennae, revealing they are extremely young, heavily obscured, and account for ~60% of the ionizing luminosity.
A new fitting methodology applied to UV absorption data recovers radial trends in galactic wind velocities and mass-loading factors by constraining initial hot and cool phase parameters in a multiphase model.
A JWST census detects neutral ISM absorption in 76 of 309 galaxies at 0.6<z<4 and outflows in 26, indicating AGN-driven neutral outflows dominate in quiescent systems at cosmic noon.
Spectroscopic observations of six low-mass, metal-poor SLSN host galaxies reveal slow stellar-wind-driven outflows with velocities 37-104 km/s and mass-loading factors below 1 in the earliest phases of star formation.
Calculations indicate low microlensing rates through NGC1052-DF2 but O(1-10) events per year possible across the sky with LSST monitoring, potentially enabling independent IMF estimates in UDGs.
GRB 160425A contains a short merger-like burst and a long collapsar-like burst separated by four minutes, challenging standard GRB classification and progenitor models.
In 37 massive ETGs, the IMF becomes less bottom-heavy with radius, with average α_IMF falling from 2.16 to 1.74 and IMF gradients dominating M/L variations over stellar population effects.
UV/optical attenuation underpredicts IR luminosity by 3-10x across 0<z<7 while κ_UV/κ_FIR falls by over an order of magnitude, pointing to evolving dust grain properties in average galaxies.
ALMA survey of CO(7-6) and [C I](2-1) in 18 z~6 quasars yields molecular gas mass estimates from multiple tracers and indicates that PDR models cannot fully account for the observed excitation, pointing to additional heating processes.
Low-mass Paβ emitters in the Spiderweb protocluster show enhanced star formation rates compared to field galaxies, with no significant deviation at higher masses.
Resolved HI observations of six baryon-dominated dwarf galaxy candidates show four are dark-matter deficient with high baryon efficiency, two in isolated environments without tidal signs.
JWST observations of ERQs show stratified gas kinematics via deblended optical emission lines, with UV lines dominated by scattered light and optical lines mixing scattered and obscured emission.
Multi-phase observations of NGC 1427A indicate tidal torquing from a dwarf fly-by has pre-conditioned its gas for ram-pressure stripping by the Fornax intracluster medium, placing the galaxy at the onset of environmental quenching with a declining star formation rate.
Two z~6.6 galaxies host overmassive black holes and show remnant ionized bubbles from recent quasar episodes, with BH-to-stellar mass ratios 400-800 times above the local relation.
A massive galaxy at z=9.3 shows bursty star formation with a recent downturn and sits in a small ionized bubble in a neutral IGM.
BAGPIPES fitting of 9289 massive quiescent galaxies shows most SFHs rise gradually then quench in 1-2 Gyr, with faster quenching at z>1 and slower at z<1, interpreted as multiple AGN feedback and gas-supply mechanisms.
