Interpreting cosmic birefringence and DESI data with evolving axion in ΛCDM
Recent cosmological observations have revealed growing tensions with the standard ΛCDM model, including indications of isotropic cosmic birefringence and deviations from w=−1 in the dark energy equation of state, as suggested by DESI and supernova measurements. In this paper, we point out that such...
