Anisotropy in the sky distributions of the short and intermediate gamma-ray bursts: Breakdown of the cosmological principle?

TL;DR

This paper discusses the anisotropic sky distributions of short and intermediate gamma-ray bursts and explores their implications for the cosmological principle.

Contribution

It presents evidence of anisotropy in both short and intermediate gamma-ray bursts, challenging the assumption of isotropy in the universe.

Findings

Anisotropy confirmed in intermediate gamma-ray bursts

Anisotropy also proven in short gamma-ray bursts

Implications for the cosmological principle discussed

Abstract

After the discovery of the anisotropy in the sky-distribution of intermediate gamma-ray bursts recently also the distribution of the short gamma-ray bursts is proven to be anisotropic. The impact of these behaviors on the validity of the cosmological principle is shortly discussed.
