Starburst Nuclei and Cosmic-Rays Transport Mechanisms: Future Opportunities for Neutrino Astronomy and Beyond Standard Model Studies

Abstract

Experimental observations have demonstrated a strong correlation between star-forming processes and gamma-ray luminosities, giving strong hints about the nature of the Cosmic-Rays (CRs) transport mechanisms inside Starburst Nuclei. In this contribution, we discuss the imprints on nearby Starburst galaxies (SBGs) gamma-ray spectra left by different CR transport models, quantifying the potentiality of future telescopes to distinguish between them. We also investigate the possibility of constraining the properties of light Dark Matter (DM) particles exploiting the peculiar nature of CR transport inside SBNs. We show that the property of scattering between high-energy CRs and DM particles leads to observable features, thereby posing stringent constraints on the DM parameter space.

Disentangling Cosmic-Ray Transport inside Starburst Nuclei with Gamma-ray and Neutrino Telescopes

“…We have also argued how crucial this will be for neutrino astronomy and in particular for unveiling the origin of the extragalactic HESE spectrum. Finally, we also comment that upcoming neutrino telescopes such as KM3NeT [11,26] are also expected to probe neutrino emission from local SBGs [27][28][29][30] (as pointed out by Ref. [16]), proving that these sources are definitely neutrino emitters.…”
