Quantum-Spacetime Scenarios and Soft Spectral Lags of the Remarkable GRB130427A
Figure 12
Here shown is the Fermi-LAT sequence of photons with energy greater than 1.5 GeV for GRB090926A. We visualize an error bar at the level for the energy of the two most energetic events. (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 (2.106 being the redshift of GRB090926A) dictated by our (1).
