Predicted gamma-ray image of SN 1006 due to inverse Compton emission

TL;DR

This paper introduces a method to generate gamma-ray images of supernova remnants from radio and X-ray data, successfully applied to SN 1006, revealing insights into the origin of its gamma-ray emission.

Contribution

A novel approach to synthesize gamma-ray images from radio and X-ray data, validated on SN 1006, linking multi-wavelength observations to emission mechanisms.

Findings

Synthesized gamma-ray images match H.E.S.S. observations.

Strong correlation between gamma-ray and X-ray/radio morphology.

Supports leptonic origin of gamma-ray emission in SN 1006.

Abstract

We propose a method to synthesize the inverse Compton (IC) gamma-ray image of a supernova remnant starting from the radio (or hard X-ray) map and using results of the spatially resolved X-ray spectral analysis. The method is successfully applied to SN 1006. We found that synthesized IC gamma-ray images of SN 1006 show morphology in nice agreement with that reported by the H.E.S.S. collaboration. The good correlation found between the observed very-high energy gamma-ray and X-ray/radio appearance can be considered as an evidence that the gamma-ray emission of SN 1006 observed by H.E.S.S. is leptonic in origin, though the hadronic origin may not be excluded.
