abstract
Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolution of these correlations requires precise measurements of the masses of distant black holes. We observe the gravitationally lensed quiescent galaxy MRG-M0138, at redshift 1.95, using JWST integral field spectroscopy to spatially resolve the kinematics of stars within the black hole's sphere of influence. By using a foreground lens model and fitting stellar dynamical models, we determine the mass of its inactive black hole, $M_{\bullet}=6.0^{+2.1}_{-1.7}\times10^9$ solar masses. Comparing this measurement to local galaxies, we find that $M_{\bullet}$ is higher than expected given the galaxy's bulge mass, but consistent with the correlation with stellar velocity dispersion.

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.
JWST-SUSPENSE spectra of eight quiescent galaxies at z~1.2-2.2 reveal negative age gradients, flat [Fe/H], and positive [Mg/H] and [Mg/Fe] gradients, suggesting inside-out quenching with Mg-deficient cores.
Extended [CII] emission reveals a large cold gas halo around the z=7.27 quiescent galaxy RUBIES-UDS-QG-z7, with gas mass estimates indicating f_gas >20% and possible past AGN-driven outflow.
Detection of [NeV]λ3427 in six recently quenched high-redshift galaxies reveals quasar-like SMBH activity persisting 100-200 Myr after the main quenching epoch.
Massive galaxies quench via either rapid supermassive black hole outflow-driven shutdown or gradual gas exhaustion, virial heating, or preventative feedback, each with distinct signatures.
