The Status of the Radio Neutrino Observatory in Greenland

ORAL

Abstract

Neutrinos are the ideal messenger for high-energy astrophysics. Weakly interacting and uncharged, they propagate undeterred and unabsorbed through the universe. Embedded radio experiments can detect the coherent radio emission from neutrino interactions in ice using a sparse array of detectors to build enormous neutrino target volumes at the highest energies (> PeV scale). Currently under construction at the NSF-run Summit Station in Greenland, the Radio Neutrino Observatory in Greenland (RNO-G) consists of 35 autonomous stations that will comprise the first neutrino telescope with access to the Northern sky at the highest energies. Each station includes a deep component deployed with a phased array trigger and a surface component for event characterization and cosmic ray identification. We will present the status of the instrument and its construction and its connection as a testbed for the radio array for IceCube-Gen2.

*We are thankful to the staff at Summit Station for supporting our deployment work in every way possible. Also to our colleagues from the British Antarctic Service for embarking on the journey of building and operating the BigRAID drill for our project. We would like to acknowledge our home institutions and funding agencies for supporting the RNO-G work; in particular the Belgian Funds for Scientific Research (FRS-FNRS and FWO) and the FWO programme for International Research Infrastructure (IRI), the National Science Foundation (NSF Award IDs 2118315, 2112352, 211232, 2111410) and the IceCube EPSCoR Initiative (Award ID 2019597), the German research foundation (DFG, Grant NE 2031/2-1), the Helmholtz Association (Initiative and Networking Fund, W2/W3 Program), the University of Chicago Research Computing Center, and the European Research Council under the European Unions Horizon 2020 research and innovation programme (grant agreement No 805486).
