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.
Seven blind lens models of MACS J0138-2155 combined with the SN Encore time delay yield H0 = 66.9^{+11.2}_{-8.1} km s^{-1} Mpc^{-1}, with forecasts for future images enabling 2-3% precision.
