No evidence for cosmological parity violation is found in the first kurto-spectrum analysis of BOSS DR12 and DESI DR1 luminous red galaxies.
Extended analysis constrains pseudo-scalar dark energy potentials using expansion history and cosmic birefringence, finding quadratic, linear, and Ratra-Peebles forms viable near GUT scale while axion-like requires large anomaly coefficient.
