Are Single-Zone Emission models Sufficient to Explain GRB 220426A and GRB 230812B?

Soumya Gupta, Sunder Sahayanathan, Saharsh Shanu +1

Gamma-ray bursts (GRBs) are the universe's most energetic phenomena (isotropic luminosity $\sim 1 0^{51} - 1 0^{54}$ ergs/s) lasting for a very short duration ( $\sim$ milliseconds -…
