Ultrahigh-energy neutrinos can be our gateway to studying some of the Universe’s most energetic but least understood phenomena. Today’s paper presents a proof-of-concept for a new, promising way to detect these ultrahigh-energy particles.
If you have a cosmic mystery on your hands, surely it helps to examine it from as many angles as possible? Today’s authors do that, literally, while investigating the highest-energy particles in the universe.
It’s looking a little (cosmic) rainy today! And the KM3NeT collaboration make the most of the muon downpour, testing for the presence of some familiar celestial bodies in their data.
Today’s astrobite looks at how we can use observations of gamma-rays and neutrinos to test our models of cosmic rays.
As the Sun bobs its head above and below the Galactic plane, the Earth’s marine microplankton flock in crowds to see the beautiful view.
How do you produce ultra-high-energy neutrinos like KM3-230213A? Guest author Domenik Ehlert explains how cosmic rays may be behind it!
