Prospects for Combined Hadronic Emission Analyses with KM3NeT and CTA — •Shivani Padma Mohan for the KM3NET-ERLANGEN collaboration — ECAP, FAU Erlangen-Nürnberg, Erlangen, Germany

Multi-messenger analysis is becoming essential to probe the fundamental astrophysical processes in distant astrophysical sources. In particular, hadronic processes, where both neutrinos and high-energy gamma rays can be simultaneously produced, motivate the combined analysis of these two messengers. KM3NeT (cubic kilometre neutrino telescope) and CTA (Cherenkov Telescope Array) are next-generation instruments with increased sensitivities in neutrino and gamma-ray astronomy, respectively, making them ideal for such joint studies. A previous study demonstrated the feasibility of a combined CTA-KM3NeT analysis using GAMMAPY, an open source Python package widely used in gamma-ray astronomy. Due to its flexible framework, it can also incorporate neutrino data and was used in the study to determine the contribution of hadronic processes in well-known galactic gamma-ray sources. To facilitate future studies involving different messengers, source classes and detector configurations, the analysis pipeline has now been updated to the latest GAMMAPY 2.0 framework. Based on the current Monte-Carlo simulations, the updated Instrument Response Functions (IRFs) for KM3NeT will be presented in comparison with earlier results.
