Discovery of the linear energy-dependence of the spectral lag of X-ray bursts from SGR J1935+2154
Shuo Xiao, You-Li Tuo, Shuang-Nan Zhang +31
Spectral lag of the low-energy photons with respect to the high-energy ones is a common astrophysical phenomenon (such as Gamma-ray bursts and the Crab pulsar) and may serve as a k…
