Unfolding the Crab Nebula Flux with Gammapy^* — •Noah Biederbeck and Maximilian Linhoff — TU Dortmund University, WG Elsässer

In spectral analyses of astrophysical gamma-ray sources, a flux model is typically fitted. Unfolding has the advantage over fitting that it is model independent and correctly includes all known detector effects. Gammapy is a widely used open-source Python package for gamma-ray astronomy, but is lacking unfolding functionality. In this talk, we present the implementation of unfolding in Gammapy and its application to joint flux unfolding of the Crab Nebula using public data of multiple Imaging Atmospheric Cherenkov Telescopes.
