Sensitivity of BEACON to Ultra-High Energy Diffuse and Transient Neutrinos

Andrew Zeolla, Jaime Alvarez-Muñiz, Sergio Cabana-Freire +16

Ultra-high energy neutrinos ( eV) can provide insight into the most powerful accelerators in the universe, however their flux is extremely low. The Beamforming Elevated…

Detector Requirements for Model-Independent Measurements of Ultrahigh Energy Neutrino Cross Sections

Ivan Esteban, Steven Prohira, John F. Beacom

The ultrahigh energy range of neutrino physics (above ), as yet devoid of detections, is an open landscape with challenges to be met and discoveries to…

The Giant Radio Array for Neutrino Detection (GRAND) Collaboration -- Contributions to the 39th International Cosmic Ray Conference (ICRC 2025)

Jaime Álvarez-Muñiz, Rafael Alves Batista, Aurélien Benoit-Lévy +133

The Giant Radio Array for Neutrino Detection (GRAND) is an envisioned observatory of ultra-high-energy particles of cosmic origin, with energies in excess of 100 PeV. GRAND uses la…

New Constraints on Macroscopic Dark Matter Using Radar Meteor Detectors

Pawan Dhakal, Steven Prohira, Christopher V. Cappiello +3

We show that dark-matter candidates with large masses and large nuclear interaction cross sections are detectable with terrestrial radar systems. We develop our results in close co…

Seasonal Variation of Polar Ice: Implications for Ultrahigh Energy Neutrino Detectors

Alexander Kyriacou, Steven Prohira, Dave Besson

The upper to of the polar ice sheet, called the firn, has a time-dependent density due to seasonal variations in the surface temperature and…

Prospects for High-Elevation Radio Detection of >100 PeV Tau Neutrinos

Stephanie Wissel, Andrés Romero-Wolf, Harm Schoorlemmer +16

Tau neutrinos are expected to comprise roughly one third of both the astrophysical and cosmogenic neutrino flux, but currently the flavor ratio is poorly constrained and the expect…

High-Energy and Ultra-High-Energy Neutrinos

Markus Ackermann, Sanjib K. Agarwalla, Jaime Alvarez-Muñiz +43

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy physics. With energies far beyond solar, supernovae, atmospheric, and accelerator neutrinos, h…

Coherent transition radiation from the geomagnetically-induced current in cosmic-ray air showers: Implications for the anomalous events observed by ANITA

Krijn D. de Vries, Steven Prohira

We show that coherent transition radiation from the electrically-neutral transverse geomagnetic current (CTR- GM) in a cosmic-ray air shower provides a natural, standard model, exp…

The forest as a neutrino detector

Steven Prohira

The primary challenge in detecting ultrahigh energy (UHE) neutrinos with energies exceeding eV is to instrument a large enough volume to detect the extremely low flux, wh…
