Description
The ANTARES telescope was a cherenkov neutrino telescope in the Mediterranean Sea which has taken data for 15 years. KM3NeT/ARCA is an astrophysical neutrino detector currently under construction, but already taking data. We present a binned likelihood stacking framework combining the two experimental datasets: the 15 years of ANTARES and the different KM3NeT/ARCA configurations (6, 8, 19 and 21 lines). We search for hot-coronae neutrino emission, both in a model-dependent and model-independent approach. For the former, we test the state-of-the-art hot corona models for 9 local Seyfert Galaxies. For the latter, we construct a catalogue of 30 Seyfert Galaxies using the B.A.S.S. AGN catalogue. We show our results testing both signal hypotheses comparing them with those recently published by the IceCube collaboration. The results of our analysis are useful for constraining the diffuse emission of these sources to the diffuse neutrino flux.
