"Constraining the High-energy Emission of NGC 1068"

Abstract:  Active galactic nuclei (AGNs) powered by accretion onto supermassive black holes produce intense radiation and high-energy particles. The nearby Seyfert 2 galaxy NGC 1068, the first non-blazar AGN linked to neutrinos, remains faint and unresolved in gamma rays, motivating tests of emission models with next-generation observatories. This work evaluates the Cherenkov Telescope Array Observatory’s (CTAO) ability to detect and distinguish high-energy emission scenarios for NGC 1068. Gammapy-based CTAO simulations are performed for 50–150 h exposures across starburst and AGN-driven models. Most models exceed CTAO’s 5 sigma threshold within 100 h, and all but the faintest remain detectable at 150 h. At that exposure, CTAO can begin to marginally discriminate between starburst and AGN-driven wind scenarios. These results establish NGC 1068 as a benchmark CTAO target, constraining hadronic acceleration in obscured AGNs and advancing multi-messenger studies of Seyfert galaxies.
