Hunting ultra high energy neutrinos with the ANITA experiment - Speaker: Dr Linda Cremonesi (UCL)

Ultra high energy (UHE) neutrinos are the perfect tool to study the most remote corners of the universe. A guaranteed flux of UHE neutrinos should come from cosmic rays interacting with the cosmic microwave background, offering insights into cosmic ray sources and compositions, and at the same time providing unprecedented constraints on neutrino interaction and oscillation models.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 UHE 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. This talk will present the challenges of neutrino astronomy, an overview of the ANITA experiment, the latest results of the third flight, and improvements towards future flights.
