A multiphase ISM grain-size model with low supernova dust yield reproduces observed dust-to-stellar mass ratios and UV luminosity functions at z=7-12 by letting small grains seed rapid metal accretion.
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.
New high-redshift quiescent galaxy sample shows size decreasing with redshift and wavelength, with stellar mass plus redshift sufficient to predict size but large residual scatter.
The NIKA2 survey delivers catalogs of 323 mm-selected sources in COSMOS with redshifts peaking at z=2.8, including 66 at z>4, matching SIDES simulations but inconsistent with four other galaxy evolution models.
