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.

Optically thin HC3N/HC5N isotopologues yield 12C/13C ≈ 37 (≈48 after fractionation correction) in G+0.693, matching 3–5 kpc disc gas and implying bar-driven inflow into the CMZ.
JWST auroral-line selected galaxies at high redshift show an MZR slope of 0.38 with selection biases favoring high-SFR low-metallicity systems, while stacked non-detections lie closer to the fundamental metallicity relation.
Chemically decoupled massive galaxies in IllustrisTNG dominate the high end of a present-day habitability proxy by over an order of magnitude due to a trade-off between suppressed planet formation and reduced sterilizing events.
Switching between four common stellar population synthesis models produces systematic offsets of up to 0.6 dex in stellar mass and 0.4 dex in star formation rate for the same galaxies.

The habitability trade-off: Chemical decoupling and quenching in massive galaxies
Chemically decoupled massive galaxies in IllustrisTNG dominate the high end of a present-day habitability proxy by over an order of magnitude due to a trade-off between suppressed planet formation and reduced sterilizing events.
