The ARA Collaboration announces today the first results using data taken during 10 months in 2013. Researchers performed a search for UHE neutrinos that resulted in no neutrino candidates but allows setting a neutrino flux limit in the energy range where most UHE neutrinos are expected to be observed. These results, submitted today to Physical Review D, significantly improve on those published a few months ago with the prototype testbed station and prove that ARA is on a good track in the quest for GZK neutrinos.
You might not know you’re at the South Pole from the photo of this watermelon. But there it is, growing in the greenhouse at the station, only a little bigger than a tennis ball at the moment. With it’s supportive, handmade hammock, hopefully it will reach a nice size and ripeness for the crew to enjoy.
