First ALMA [CII] observations of high-redshift quiescent galaxies reveal gas fractions from 0.1% to 25%, dust temperatures of 40-50 K, strong [CII] deficits, and merger-like features, suggesting merger-driven quenching with non-stellar dust heating.

Neutral outflows detected in 57% of z~3.5 quiescent galaxies via NaI D, with mass rates that can suppress star formation but suggest short-timescale recycling instead of permanent quenching.
Using JWST photometry of ~17,000 galaxies, the median Balmer break strength decreases from 1.5 to 1.1 (flux ratio) from z~3.5 to z~10, driven by stellar population age, with rare extremely strong breaks at both epochs tracing distinct populations.
Half of strong CIII] emitters at z=5-7 show secure AGN signatures, with median equivalent width rising 0.67 dex relative to z=3-4 galaxies.
