Spectral Lag for a Radiating Jet Shell with a High Energy Cut-off Radiation Spectrum
arXiv:1907.08806 · doi:10.3847/1538-4357/ab33fe
Abstract
Recent research shows that the spectral lag is closely related to the spectral evolution in GRBs. In this paper, we study the spectral lag for a radiating jet shell with a high-energy cut-off radiation spectrum. For the jet shell with a cut-off power-law spectrum, the spectral lag monotonically increases with the photon energy and levels off at a certain photon energy. It is the same for the jet shell with a Band cut-off spectrum (Bandcut). However, a turn-over from the positive lags to negative lags appears in the high-energy range for the jet shell with Bandcut, which is very similar to that observed in GRB~160625B. The dependence of the spectral lags on the spectral shape/evolution are studied in details. In addition, the spectral lag behavior observed in GRB~160625B is naturally reproduced based on our theoretical outcome.
