Upcoming neutrino telescopes may discover ultra-high-energy (UHE) cosmic
neutrinos, with energies beyond 100 PeV, in the next 10–20 years. Finding
their sources would expose the long-sought origin of UHE cosmic rays. We search
for sources by looking for multiplets of UHE neutrinos arriving from similar
directions. Our forecasts are state-of-the-art, geared at neutrino
radio-detection in IceCube-Gen2. They account for detector energy and angular
response, and for critical, but uncertain backgrounds. We report powerful
insight. Sources at declination of $-45^circ$ to $0^circ$ will be easiest to
discover. Discovering even one steady-state source in 10~years would disfavor
most known steady-state source classes as dominant. Discovering no transient
source would disfavor most known transient source classes as dominant. Our
results aim to inform the design of upcoming detectors.
