Spiral arms and bars are galactic fuel pumps for star formation
Peak star formation took place during cosmic noon, between 2–3 billion years after the Big Bang. The star formation rate (SFR) back then was up to 100 times greater than it is today. For the SFR to be so high, gas had to move through galaxies efficiently.
