Search for gamma-ray emission from solar system bodies with Fermi-LAT

TL;DR

This paper reports on the search for gamma-ray emissions from solar system bodies, including planets, using Fermi-LAT data, building on previous detections of the Moon and Sun.

Contribution

It presents the ongoing search for gamma-ray emission from major planets with Fermi-LAT, expanding the study beyond the Moon and Sun.

Findings

Detected gamma-ray emission from the Moon and Sun.

Conducted initial search for emission from planets.

Results are preliminary and part of ongoing analysis.

Abstract

FERMI-LAT is performing an all-sky gamma-ray survey from 30 MeV to $>$300 GeV with unprecedented sensitivity and angular resolution. FERMI has detected high-energy gamma rays from the Moon and Sun since the first weeks of data taking. This emission is produced by interactions of cosmic rays with these objects. Similarly, some gamma ray emission can be produced by interactions with asteroids and planets. We have searched this emission looking major planets during the first 6 months of data taking. We present here the status of the search.
