Nova neutrinos in the multi-messenger era (original) (raw)

Journal of Cosmology and Astroparticle Physics

Abstract

The recently discovered high energy emission from the recurrent nova RS Ophiuchi by Fermi-LAT (> 100 MeV), H.E.S.S. and MAGIC (>100 GeV), hints towards a possible hadronic origin of this radiation component. From the observed high energy photon flux we derive the expected number of neutrino events that could be detected by present and future neutrino telescopes in the different energy ranges. Preliminary estimates indicate that with the “next-generation” instrument IceCube-Gen2, the expected number of neutrino detections from Galactic novae, admittedly with large uncertainty, should not exceed 1 event per decade.
