Description
Ultra-high-energy neutrinos offer a unique window on the most violent phenomena in the Universe. Produced at astrophysical sources or during cosmic-ray propagation, these unattenuated and unscattered cosmic messengers probe environments inaccessible to other particles. They enable the study of their production sites, may reveal the sources of ultra-high-energy cosmic rays, and help constrain their mass composition. Their extremely low flux requires the instrumentation of vast volumes of transparent media for detection.
Radio detection via the Askaryan effect has emerged as a promising and cost-effective approach to instrument large volumes of ice with sparse arrays reaching the required sensitivities.
The Radio Neutrino Observatory in Greenland (RNO-G) is a third-generation radio neutrino array currently under construction at Summit Station. Stations have been deployed and operating for the past five years, delivering already science results. RNO-G is planned to have 35 hybrid stations in total, each capable of detecting neutrino-induced signals, reconstructing event properties, and rejecting cosmic-ray backgrounds.
In this contribution, I will present the current status of construction, commissioning, and calibration, as well as the first scientific results obtained with data from the deployed stations.
