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.
LAEs at z=2.4-4.5 are smaller and more starbursting than typical SFGs, with Lyα strength correlating negatively with size and positively with Sersic index and recent SFR ratio.
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.
Simulations indicate SKAO AA4 surveys can trace thermal and nonthermal ISM processes in high-redshift galaxy analogs beyond z=1-3, underscoring nonthermal feedback at cosmic noon.
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.
