Antarctic Impulsive Transient Antenna: A Long Duration Balloon High Energy Neutrino Observatory
Peter Gorham (PI), University of Hawaii at Manoa
ANITA will establish the first high energy neutrino observatory among NASA missions, using the entire Antarctic ice sheet as a collecting aperture for particles which originate in the most extreme environments in the universe: the inner edges of massive black hole accretion disks, the intense radiation fields within gamma-ray burst sources, and the collisions of the highest energy cosmic rays in the universe with the cosmic microwave background radiation integrated over the entire volume of our visible universe. A balloon payload at nearly 40km altitude can observe 1.5M cubic km of extremely radio-transparent ice out to its visible horizon. Neutrinos at EeV energies interact within the ice and produce an intense, compact particle shower, several m in length and cm in diameter. Pulsed radio emission from these intense showers is visible at great distances, and the radio quiet environment of Antarctica will facilitate their detection.
