TNG50 shows most massive high-z star-forming galaxies are dynamically hotter than ALMA data indicate, with rare cold discs forming from aligned accretion and evolving into one-third discs and two-thirds early-type galaxies by z=0.
CO observations of the COSMOS-Gr30 group at z~0.7 show average molecular gas contents reduced by 0.5 dex relative to field galaxies, with gas fractions 20-40% of main-sequence values, plus an upper limit on cold gas in the extended ionized structure.
Simulations show that bursty supernova feedback produces fewer bright [OIII] emitters by z=5 than smooth feedback due to less effective metal enrichment, while [OIII] traces shock-heated and radiatively ionized gas.

Probing the molecular gas content of galaxies in an over-dense group at z~0.7: a test case for environmental quenching
CO observations of the COSMOS-Gr30 group at z~0.7 show average molecular gas contents reduced by 0.5 dex relative to field galaxies, with gas fractions 20-40% of main-sequence values, plus an upper limit on cold gas in the extended ionized structure.

New constraints on stellar feedback through [O III] emission: interpreting ALMA and JWST observations with SPICE simulations
Simulations show that bursty supernova feedback produces fewer bright [OIII] emitters by z=5 than smooth feedback due to less effective metal enrichment, while [OIII] traces shock-heated and radiatively ionized gas.
