abstract
Most present-day galaxies with stellar masses $\geq10^{11}$ solar masses show no ongoing star formation and are dense spheroids. Ten billion years ago, similarly massive galaxies were typically forming stars at rates of hundreds solar masses per year. It is debated how star formation ceased, on which timescales, and how this "quenching" relates to the emergence of dense spheroids. We measured stellar mass and star-formation rate surface density distributions in star-forming galaxies at redshift 2.2 with $\sim1$ kiloparsec resolution. We find that, in the most massive galaxies, star formation is quenched from the inside out, on timescales less than 1 billion years in the inner regions, up to a few billion years in the outer disks. These galaxies sustain high star-formation activity at large radii, while hosting fully grown and already quenched bulges in their cores.

In the AMBRA simulation, little red dots are existing black hole-galaxy systems caught in a bright, temporary phase that lasts roughly 3 to 300 million years and scales with host and black hole mass.
About 44% of little red dots have hydrogen-alpha absorption from outflowing gas, implying radiatively driven outflows rather than static atmospheres.
In the Simba simulation, temporary quiescence, a low CO-to-H2 conversion factor, and dust-obscured star formation can each explain molecular gas in quenched massive galaxies, with importance shifting with redshift.
Bulgeless galaxies trace the upper envelope of the mass-R1 relation with scatter driven by central stellar density and the spatial configuration of mergers rather than their number.
Image stacking of 57 E+A galaxies shows excess extended light relative to comparison samples, consistent with faint tidal features from small-scale interactions.
This white paper argues that ALMA2040 is essential to systematically measure molecular gas, dust, and outflows in quiescent galaxies and discriminate between quenching mechanisms.
