Abstract Ultra-high-energy (UHE) neutrinos (> 1 0 16 eV) can be measured cost-effectively
using in-ice radio detection, which has been explored successfully in pilot arrays. A large …

The origin of high-energy cosmic rays, and their behavior in astrophysical sources, remains
an open question. Recently, new ways to address this question have been made possible …

Soon, a new generation of neutrino telescopes, presently under planning, will target the
discovery of ultra-high-energy (UHE) neutrinos of cosmic origin, with energies higher than …

Ultralight bosons can grow substantially in the vicinity of a black hole, through superradiant
energy extraction. Consequently, such bosons can potentially reach field values close to the …

Ultra-high-energy (UHE) cosmic neutrinos, with energies above 100~ PeV, could be finally
discovered in the near future. Measuring their flavor composition would reveal information …

High-energy astrophysical neutrinos, with TeV--PeV energies, offer unique insight into
astrophysics and particle physics. Their incoming directions and flavor composition--ie, the …
