Quantum-Spacetime Scenarios and Soft Spectral Lags of the Remarkable GRB130427A

Figure 13

Here shown is the Fermi-LAT sequence of photons with energy greater than 1 GeV for GRB090902B. We visualize an error bar at the 15% level for the energy of the most energetic event. (b) A straight line with the slope we derived in Section 3. (a) Some straight lines with slope obtained from the slope derived in Section 3 by rigidly rescaling it by the factor of 𝐷(0.34)/𝐷(1.822) dictated by our (1) for a GRB at redshift of 1.822.
