Discovery and characterization of the highest-redshift barred spiral galaxy candidate at z=5.102, with bar length ~4.5 kpc, stellar mass 10^10.45 solar masses, SFR 144 solar masses per year, and evidence for AGN and interaction.

A new catalogue of bar lengths and widths from HST images of 8230 galaxies shows bars are about 13% weaker at higher redshift, with longer bars in higher-mass quiescent galaxies and trends consistent with slow 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.
Strong bars correlate with massive red galaxies, boost central star formation in low-mass systems while quenching it in high-mass ones, and increase AGN incidence, supporting bar-driven gas inflow.
