Towards a multiwavelength analysis of Pulsar Wind Nebulae at gamma-ray and X-ray energies with Gammapy — •Katharina Egg and Alison Mitchell — Erlangen Centre for Astroparticle Physics (ECAP), Friedrich-Alexander-Universität Erlangen Nürnberg

Pulsar wind nebulae (PWNe) are structures produced by the outflow of highly energetic particles from pulsars. As regions harbouring extreme physical conditions, PWNe are possible PeVatron candidates (accelerators of particles to PeV energies). While many PWNe have been detected and even first discovered as sources of gamma-ray emission, the particle winds driving this process are expected to cause the emission of photons across the entire electromagnetic spectrum. Thus the study of PWNe in multiple energy bands is key to constrain their characteristics and environments.

In this vein, data from the eROSITA X-ray telescope, in conjunction with gamma-ray data from the H.E.S.S. telescope array, provides the opportunity of studying even very faint X-ray counterparts of PWNe on large scales. This analysis is undertaken using the Gammapy package that is developed for the handling of gamma-ray data in a Python framework. In this contribution, the capabilities of Gammapy in the combined handling of X-ray and gamma-ray data are explored and the process towards the goal of conducting a joint analysis of X-ray and gamma-ray data is showcased.
