Kinematic Origin OF Correlations Between Gamma Ray Burst Observables

TL;DR

This paper demonstrates that newly observed correlations between gamma-ray burst (GRB) properties can be explained by the kinematic effects of relativistic jets in the cannonball model, unifying them with previously known correlations.

Contribution

It shows that the new GRB correlations originate from the same kinematic principles as earlier correlations within the cannonball model.

Findings

New correlations are explained by Lorentz and Doppler factor dependencies.

The model unifies various GRB correlations under a common kinematic origin.

Supports the cannonball model as a viable explanation for GRB observables.

Abstract

Recently, several new correlations between gamma ray burst (GRB) observables have been discovered. Like previously well established correlations, they challenge GRB models. Here we show that in the cannonball (CB) model of GRBs, these newly discovered correlations have the same simple kinematic origin as those discovered earlier. They all result from the strong dependence of the observed radiations on the Lorentz and Doppler factors of the jet of highly relativistic plasmoids (CBs) that produces the observed radiations by interaction with the medium through which it propagates.
