Searching for UHE Cosmic Neutrinos with the Radio Cerenkov Technique
Time: 3:30 pm - 4:30 pm
Place: 5280 Chamberlin
Speaker: Amy Connolly, Ohio State University
Abstract: There are strong motivations for a detectable flux of ultra-high energy (UHE) cosmic neutrinos above 10$^{17-18}$~eV both from cosmic ray interactions with cosmic microwave background photons and directly from UHE astrophysics sources. The radio Cerenkov technique is the most promising technique for instrumenting a detection volume large enough to sustain a long-term program measuring the low expected fluxes at the highest energies. The ANtarctic Impulse Transient Antenna (ANITA) is a balloon-borne antenna array that searches for radio impulses from neutrino interactions from 37 km above the Antarctic ice sheet. Its third flight under NASA's long-duration balloon program is planned for the end of 2014. <br>
I will present the world's best limits above 10^{19} eV from ANITA, and plans for both ANITA 3 and the future balloon project EVA.<br>
The Askaryan Radio Array (ARA) is an antenna array being deployed at 200 meter depth near the South Pole. I will present the results of ARA's first search for UHE neutrinos using a prototype Testbed station in shallow ice. The first stations of the proposed 100 km^2 area array have been deployed and neutrino searches with these stations is underway. I will also address the implications of current and future UHE neutrino measurements for particle physics and astrophysics.<br>
