Description
The Askaryan Radio Array (ARA) is a neutrino telescope array under phased deployment near the South Pole. The array aims at discovering and determining the ultra-high energy neutrino flux via detection of the Askaryan signal from neutrino-induced showers. This novel detection channel makes ARA the most cost-effective neutrino observatory in probing the neutrino flux from ~ 100PeV – 10EeV. Currently three stations are operational, with two more stations to be added in the 2017-2018 Pole season.
This contribution will discuss various new analysis techniques developed for the ARA, including an interferometric reconstruction taking into account the curved paths traveled by EM radiation in inhomogeneous ice. Preliminary results of diffuse neutrino search using 2013-2014 data from 2 stations using the background rejection and interferometric reconstruction techniques discussed here and earlier will also be presented.
