Deep interferometric observations of a z≈1.12 barred spiral reveal bar-driven molecular inflows at a rate matching the galaxy's star formation rate of ~36 M⊙/yr.
JWST imaging reveals a z=0.92 disk galaxy with an X-shaped bulge, nuclear stellar disk, and extended disk whose bar geometry matches present-day systems, showing bar-driven secular evolution largely complete 7.6 Gyr ago.
SIDM halos accelerate bar formation and growth in disk galaxies through enhanced angular momentum exchange, independent of core formation.
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.
