Physics of Gamma-Ray Bursts Prompt Emission

Figure 10

Light curve of the emission of GRB090510 above 100 MeV extends to >100 s and can be fitted with a smoothly broken power law. The times are scaled to the time  s after the GBM trigger. The inset shows the AGILE light curve (energy range 30–300 MeV), extending to much shorter times. Figure taken from Ghirlanda et al. [113].
