The Radio Neutrino Observatory

The Radio Neutrino Observatory (RNO) aims to probe the astrophysical neutrino flux at energies from 30 PeV and up, discover an ultra-high energy counterpart, and employ a multi-pronged approach to characterize neutrinos for multi-messenger astrophysics. While IceCube has measured a cosmic neutrino flux up to ~10 PeV, at higher energies greater exposure is needed. RNO will consist of 61 stations of radio antennas deployed near South Pole. The stations’ receivers will deployed at a depth in the ice due to the higher effective volume and sky coverage for astrophysical neutrinos. An RNO surface array component will play an important role in measuring neutrino properties as well as cosmic rays. We will present the RNO design and its motivation in terms of its unique, multi-messenger science program, as well as the timeline for deployment and results. RNO brings together a broad coalition from the in-ice radio neutrino community and is currently in the proposal phase.
