Hunting ultra high energy neutrinos in Antarctica

by Dr Linda Cremonesi (Queen Mary University of London)

Zoom (Online)




The ANtarctic Impulsive Transient Antenna (ANITA) is a long-duration balloon payload funded by NASA, with an array of radio antennas. ANITA scans the Antarctic ice looking for Askaryan radio emission coming from ultra-high-energy (>E18 eV) neutrinos interactions. Extensive air showers coming from ultra-high-energy cosmic rays and hadronic showers from tau neutrinos can also be detected by ANITA via geomagnetic radio emission. ANITA currently has the best limit on cosmogenic neutrinos above E19 eV. This talk will present an overview of the ANITA experiment, the latest results of the third and fourth flight, and improvements towards future flights.
