Conical Fireballs, Cannonballs, And Jet-Breaks In The Afterglows Of Gamma Ray Bursts

TL;DR

This paper compares two models of gamma-ray burst afterglows, finding that the Cannonball model better explains observed correlations than the traditional conical fireball model.

Contribution

It provides evidence favoring the Cannonball model over the conical fireball model in explaining GRB afterglow correlations.

Findings

Correlations align with Cannonball model predictions.

Conical fireball model predictions are inconsistent with observed correlations.

Supports alternative jet structure models for GRBs.

Abstract

The 'jet-break' in the X-ray afterglow of gamma ray bursts (GRBs) appears to be correlated to other properties of the X-ray afterglow and the prompt gamma ray emission, but the correlations are at odds with those predicted by the conical fireball model of GRBs. The correlations are in good agreement, however, with those predicted by the Cannonball model of GRBs.
