In a study published in The Astrophysical Journal, Prof. Zhou Xia from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences and collaborators have, for the first time, derived the dispersion relation for photons with nonzero mass propagating in plasma, and established a stringent upper limit for the photon mass at 9.52 × 10-46 kg (5.34 × 10-10 eV c-2) using data collected by ultra-wideband (UWB) receivers from pulsar timing and fast radio bursts (FRBs).
