Current Status & Future Prospects of Askaryan Radio Array

Since the last two decades, various efforts are made for the detection of ultra-high energy (E_ν ≥ 10 PeV) cosmogenic neutrinos and the Askaryan Radio Array (ARA), deployed first in 2012 at the South Pole (SP), has made major contributions towards that. It consists of five independent stations (A1-A5) with A5 equipped with a low threshold phased array. Each station is buried at a depth of 100-200 m in the 2.8 km deep SP ice sheet, and their unique and yet similar instrumentation relative to each other enable them to scan a great volume of ice in search for the highest energetic elusive neutrinos. ARA uses horizontally and vertically polarized radio dipole antennas as receivers for neutrino induced radio Cherenkov signals and as transmitters for local ice and antenna position calibration. Previously, a few stations' data over a short livetime has indicated a great potential of ARA for cosmogenic neutrino detection. In this contribution, we discuss a first ever joint five stations analysis scheme for more than two decades station livetime, benefiting from improved noise and gain models, various calibration efforts, and we present some preliminary results. We further present the future ARA neutrino detection prospects, which should afford it the best projected sensitivity limit by any in-ice radio neutrino detector above 100 PeV.
