Reply to [arXiv:1105.5147] "Are GRB 090423 and Similar Bursts due to Superconducting Cosmic Strings?"

TL;DR

This paper discusses how gamma-ray bursts driven by superconducting cosmic strings may produce arc-shaped outflows, potentially explaining high-redshift GRB observations.

Contribution

It proposes that cosmic string-driven GRB outflows are arc-shaped, offering a new perspective on their afterglow characteristics and observational consistency.

Findings

Arc-shaped outflows can match high-redshift GRB observations

Cosmic string GRBs may differ from traditional spherical models

The model aligns with observed afterglow data

Abstract

The GRB outflow driven by superconducting cosmic strings is likely to be an arc rather than a usually-considered spherical cap. In such a case, the afterglows of the cosmic string GRBs could be basically consistent with the observation of the high-redshift GRBs.
