#4 The article is pretty poor. Among other little details it got wrong, low energy neutrinos interact very very weakly with matter, but high and ultra-high energy ones interact well. ANITA looks for radio waves created from charge separation in particle showers produced when those high energy neutrinos interact. It's a tricky measurement, and it isn't obvious that they understand the ice as thoroughly as they need to. OTOH, it isn't obvious that this is a detector malfunction either.
But IceCube didn't see anything, and it should have. Maybe they saw some radio reflections in the ice? |
