Revisiting constraints on the photon rest mass with cosmological fast radio bursts
Fast radio bursts (FRBs) have been suggested as an excellent celestial laboratory for testing the zero-mass hypothesis of the photon. In this work, we use the dispersion measure (DM)-redshift measurements of 23 localized FRBs to revisit the photon rest mass m γ . As an improvement over previous studies, here we take into account the more realistic
