Abstract: Cosmic rays and neutrinos provide a unique window into observations of the most violent physical phenomena in the universe. At the highest energies, the flux of these particles at Earth is incredibly low, making direct detection challenging. For neutrinos, the problem is further compounded by their miniscule interaction probabilities. By measuring emission from particle cascades sourced from cosmic ray or neutrino interactions, it is possible to cost-effectively instrument large detection volumes and improve the chances of detection. In this talk, I will introduce the method of indirect detection of these cosmic particles through the measurement of coherent radio emission, highlighting the strengths and weaknesses of the technique. I will describe many of the active experimental efforts which hunt for neutrinos using radio observations and where they fit within the landscape of high-energy multi-messenger astronomy.
