Cosmic GRB energy-redshift relation and Primordial flares as possible energy source for the central engine

TL;DR

This paper proposes that primordial solar flare-like phenomena in the early universe could be the energy source for gamma-ray bursts, supported by a derived energy-redshift relation consistent with observations.

Contribution

It introduces a novel hypothesis linking primordial flares to GRB energy sources and derives an energy-redshift relation validated by observational data.

Findings

Derived energy-redshift relation E = E_0(1+z)^3 matches observations.

Estimated physical parameters of the flaring regions.

Proposed primordial flares as a plausible GRB energy source.

Abstract

By considering similar observed properties of gamma ray bursts (GRB) and solar flares with the prevailing physical conditions in the cosmic environment, the following study suggests that most likely and promising energy source for the central engine which triggers GRB may be due to primordial flares, solar flare like phenomena, at the sites of inter galactic or inter galactic clusters in the early universe. The derived energy-redshift relation, E = E_{0}{(1+z)}^3 (where E is the amount of energy released, z is the redshift of GRB and E_{0} is a constant which is estimated to be ~ 10^{52} ergs), from the simple flare mechanism, is confirmed from the least square fit with the observed energy-redshift relation. Some of the physical parameters like length scale, strength of magnetic field, etc., of the flaring region of the GRB are estimated.
