High-energy SETI pushes astrobiology to its limits, testing the most fundamental needs of life and the most extreme limits of technology. It has lagged behind the rest of the field, but the increased respectability of SETI could spark interest in the coming years. This white paper reviews the case for SETI in X-rays, gamma rays, and neutrinos, including rationales, challenges, and possible technosignatures, and suggests future strategies for observational work.
