A galaxy at z=3.16 has a bar with older stars making up 30% of its mass but only 8% of its recent star formation, supporting inside-out galaxy formation and possible early bar quenching.
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.
