Description
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 (SBNs). In this talk, I will discuss the imprints on nearby Starburst galaxies (SBGs) gamma-ray spectra left by different CR transport models, quantifying the potentiality of future measurements from CTA and SWGO telescopes to distinguish between them. I will also investigate the possibility of constraining the properties of light Dark Matter (DM) particles exploiting the peculiar nature of CR transport inside SBNs. I will show that the property of elastic scattering between high-energy CRs and DM particles leads to observable features, thereby posing stringent constraints on the DM parameter space.
