15 Years Under the Sea: ANTARES’ Final Search for Galactic Neutrinos

The Search for Galactic Neutrinos

This episode explores the final results from the ANTARES neutrino telescope, which operated in the Mediterranean Sea off the coast of Toulon, France. Researchers analyzed the full, 15-year dataset (2007–2022) to search for diffuse Galactic neutrinos. These neutrinos are produced when cosmic rays (CRs) interact with interstellar matter (gas and radiation fields) in the Milky Way. Understanding this diffuse flux is key to deciphering cosmic ray transport mechanisms.

Testing Theoretical Models

The study utilized an unbinned maximum likelihood analysis to test several phenomenological mo...
