High-energy astrophysical neutrinos, recently discovered by IceCube up to energies of several PeV, opened a new window to the high-energy Universe. Yet much remains to be known. IceCube has excellent muon flavor identification, but tau flavor identification is challenging. This limits its ability to probe neutrino physics and astrophysics. To address this limitation, we present a concept for a large-scale observatory of astrophysical tau neutrinos in the 1-100 PeV range, where a flux is guaranteed to exist. Its detection would allow us to characterize the neutrino sources observed by IceCube, to discover new ones, and test neutrino physics at high energies. The deep-valley air-shower array concept that we present provides highly background-suppressed neutrino detection with pointing resolution <1 degree, allowing us to begin the era of high-energy tau-neutrino astronomy.

  1. POLARIS: A Sparse Radial Neutrino Telescope Design for the Pacific Ocean

    astro-ph.HE 2026-04 unverdicted novelty 6.0

    POLARIS is a radial sparse Cherenkov detector that targets the natural horizontal geometry of ultra-high-energy neutrino-induced muons to reach PeV sensitivities with only 1100 modules.

  2. TeV-PeV Gamma-ray and Neutrino Emission in the Galactic Plane

    astro-ph.HE 2026-06 unverdicted novelty 3.0

    Alternative ISRF models produce only modest changes to the LHAASO diffuse gamma-ray fit; the associated pp neutrinos remain consistent with IceCube all-sky data and compatible with ANTARES/KM3NeT limits.

    hep-ph 2026-03 accept novelty 2.0

    Correcting an omitted reality condition in the neutrino mass matrix elements allows the predicted neutrino mass sum to remain consistent with updated DESI and supernova data for both mass orderings.
