A score-based diffusion generative model on deep infrared galaxy photometry yields a star formation rate density peaking at z=1.3 and shows distinct non-parametric star formation histories plus AGN activity peaking during the quenching transition of massive galaxies.

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.
Barred galaxies transition from actively star-forming at z~1-2 to quiescent at z~0, with the fraction of quiescent galaxies hosting bars increasing steeply over cosmic time.
Multiple galaxy formation simulations show that low-mass quenched galaxies at z>3 are predominantly environmentally quenched satellites, often only temporarily so, and match JWST observations.
The SFR-M_* relation develops a high-mass decline at low redshifts, driven mainly by morphological quenching from internal structure rather than environmental effects on star-forming galaxies.
Multi-phase molecular gas in IRAS20551-4250 is dominated by cold CO, shows UV-heated warm H2, tidal features from a merger, and no molecular outflows, consistent with ongoing star formation.
Star-forming galaxies show a transition from negative to positive sSFR radial gradients around z~2, implying a change from outside-in to inside-out growth.
SEMPER predicts SKA-Mid Band 2 observations in under 20 hours will recover at least 20% of the total SFRD from radio-emitting SFGs up to z≈6, including NIR-dark galaxies.
CO observations of the COSMOS-Gr30 group at z~0.7 show average molecular gas contents reduced by 0.5 dex relative to field galaxies, with gas fractions 20-40% of main-sequence values, plus an upper limit on cold gas in the extended ionized structure.
Multi-band imaging and Keck spectroscopy identify a z=0.92 galaxy pair as a physical merger at ~5 kpc projected separation with merger-induced star formation.
Simulations show SKAO AA4 surveys can trace ISM thermal/nonthermal processes in M51/NGC6946 analogs beyond cosmic noon (z=2-3 in continuum, z>1 in HI), indicating nonthermal feedback importance at high redshift.
