Quantum-Spacetime Scenarios and Soft Spectral Lags of the Remarkable GRB130427A
Figure 14
Here shown is the Fermi-LAT sequence of photons with energy greater than 1 GeV for GRB090510. We visualize an error bar at the level for the energy of the most energetic event. (b) A straight line with the slope we derived in Section 3. (a) A straight line with slope obtained from the slope derived in Section 3 by rigidly rescaling it by the factor of (0.897 being the redshift of GRB090510), as dictated by (1).
