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.
Barred galaxies transition from actively star-forming at z~1-2 to quiescent at z~0, with the fraction of quiescent galaxies hosting bars increasing steeply over cosmic time.
Multi-wavelength observations of NGC 3351 provide evidence that the stellar bar redistributes molecular gas inward, depleting it along the bar and suppressing star formation while building a central reservoir.

Bar-driven gas redistribution suppresses star formation in spiral galaxies: Evidence from dust lanes in NGC 3351
Multi-wavelength observations of NGC 3351 provide evidence that the stellar bar redistributes molecular gas inward, depleting it along the bar and suppressing star formation while building a central reservoir.
