Description
Fermi-LAT is one of the major gamma-ray observatories in the hundreds of MeV to few TeV energies. In this work, we searched for gamma-ray emission from Jupiter using 15 years of Fermi-LAT data in the energy range from 100 MeV to 2 TeV.
Jupiter’s path on the sky was partitioned into 1202 steps, each one corresponding to a 0.5 deg displacement and a likelihood analysis was performed at each step. Afterwards all steps were stacked. No gamma-ray signal was detected and flux upper limits were derived.
Finally, under the assumption that dark matter annihilation is happening inside Jupiter and is the only possible source of gamma-ray photons, we derived constraints on the dark matter – nucleon cross section.
