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.
Bar pattern speeds anti-correlate with stellar and total dynamical mass in 30 galaxies, placing the slowest bars in the most massive systems and supporting angular momentum transfer to dark matter.
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.
