Gamma ray bursts may be blueshifted bundles of the relic radiation

TL;DR

This paper proposes that gamma-ray bursts could be explained by blueshifting hydrogen and helium radiation in a Lemaître-Tolman model with a non-uniform bang-time function, offering a novel cosmological interpretation.

Contribution

It introduces a specific Lemaître-Tolman model to account for GRBs via blueshifted relic radiation, a new approach compared to existing models.

Findings

The model qualitatively explains some observed properties of GRBs.

Blueshift occurs along radial rays where the bang-time function varies.

The approach offers a potential cosmological origin for GRBs.

Abstract

A hypothesis is proposed that the gamma-ray bursts (GRBs) may arise by blueshifting the emission radiation of hydrogen and helium generated during the last scattering epoch. The blueshift mechanism is provided by such a Lema\^itre -- Tolman (L--T) model, in which the bang-time function $t_B(r)$ is not everywhere constant. Blueshift arises on \textit{radial} rays that are emitted over regions where $\dril{t_B} r \neq 0$. The paper presents an L--T model adapted for this purpose and shows how it accounts for the observed properties of the GRBs, some properties are accounted for only qualitatively.
