The Radio Neutrino Observatory in Greenland (RNO-G) aims to detect ultra-high-energy neutrinos via Askaryan radiation; however, in-ice cosmic-ray (CR) cores produce similar radio signatures and are expected to dominate the trigger rate of RNO-G's deep, in-ice antenna channels. Using a previously reported fast-simulation method to build a simulation pipeline with the FAERIE framework, we report results from our first large-scale production campaign of in-ice shower-core simulations.
We present the trigger efficiency as a function of primary energy, zenith angle, and viewing angle, along with updates to our simulation methodology since the preliminary conference results.
This work shows how the fast simulation method makes it possible to efficiently approximate effective areas and event rates.
