Abstract:
GZK neutrinos, produced when ultra-high energy cosmic rays interact with cosmic-microwave, are the only way to probe the high-energy universe at distances beyond about 75 Mpc A very large detector is required to observe these neutrinos. Next generation experiments aim at a 100 km^3 volume, enough to collect a sample of ~ 100 events in a few years; the technology of choice is radio detection of neutrino induced showers in Antarctic ice. One such project is ARIANNA, an array that is proposed to be built on the Ross Ice Shelf.
After briefly introducing ARIANNA, I will show slides of our (Thorsten Stezelberger and I) December trip to Moore's Bay, about 70 miles south of McMurdo station, where we camped in tents for 11 days and set up a prototype station.
