Extended Data Fig. 7: Modelling of broadband light curves.
From: Observation of inverse Compton emission from a long γ-ray burst
Modelling results of forward shock emission are compared to observations at different frequencies (see key). The model shown with solid and dashed lines is optimized to describe the high-energy radiation (teraelectronvolt, gigaelectronvolt and X-ray) and has been obtained with the following parameters: s = 0, εe = 0.07, εB = 8 × 10−5, p = 2.6, n0 = 0.5 and Ek = 8 × 1053 erg. Solid lines show the total flux (synchrotron and SSC) and the dashed line refers to the SSC contribution only. Dotted curves correspond to a better modelling of observations at lower frequencies, but fail to explain the behaviour of the teraelectronvolt light curve; they are obtained with the following model parameters: s = 2, εe = 0.6, εB = 10−4, p = 2.4, A. = 0.1 and Ek = 4 × 1053 erg. Vertical bars on the data points show the 1σ errors on the flux, and horizontal bars represent the duration of the observation.
