Emission of extremely bright gamma-ray pulsar in the Large Magellanic Cloud

TL;DR

This paper presents a theoretical model explaining the emission characteristics of the gamma-ray pulsar PSR J0540-6919, including its double-peaked radio profile and gamma-ray emission, linking radio and gamma-ray phenomena.

Contribution

It introduces a novel theoretical interpretation connecting radio and gamma-ray emissions in the pulsar, explaining observed peak structures and phase coincidences.

Findings

Model explains two radio peaks and their frequency dependence.

Model accounts for phase coincidence of emission peaks.

Connects radio remission with gamma-ray emission up to GeV energies.

Abstract

In the present paper a theoretical interpretation of observational characteristics of the pulsar PSR J0540-6919 is suggested. In particular, we provide a theoretical model explaining the presence of two peaks in the radio domain and the brooding of these peaks at higher frequencies. The model also explains the pulse-phase coincidence of emission peaks at different frequencies and shows the physical, 'genetic' connection between the radio remission at frequencies of the order of GHz with gamma-ray emission up to GeV energies.
