Description
High-energy neutrinos propagating over cosmological distances are the ideal messenger particles for astrophysical phenomena, but the neutrino landscape above 10 PeV is currently completely uncharted. At these extreme energies, the best sensitivity comes from experiments detecting radiofrequency emissions from neutrino interactions in the vast polar ice sheets.
With the large-scale radio neutrino observatory RNO-G currently undergoing deployment in Greenland, and even larger arrays being planned, it is now time to address the unique detector physics challenges presented by these instruments.
In this talk, I will combine ideas from collider instrumentation with high-performance computing to show how large-scale Green's functions can be used to construct high-fidelity simulations of neutrino-induced detector signals and non-neutrino backgrounds alike. Then, using techniques originally developed for seismology and the study of elastic waves, we will see how seemingly-random ambient thermal noise can be used to monitor the geometry of the detector in-situ; once again confirming the crucial role of decade-old physics in enabling the experiments of the present.
