Initial performance of the Radar Echo Telescope for Cosmic Rays, RET-CR
P. Allison, J. Beatty, D. Besson +28
The Radar Echo Telescope for Cosmic Rays (RET-CR), a pathfinder instrument for the radar echo method of ultrahigh energy (UHE) neutrino detection, was initially deployed near Summi…
Modeling in-ice radio propagation with parabolic equation methods
S. Prohira, C. Sbrocco, P. Allison +24
We investigate the use of parabolic equation (PE) methods for solving radio-wave propagation in polar ice. PE methods provide an approximate solution to Maxwell's equations, in con…
The Payload for Ultrahigh Energy Observations (PUEO): A White Paper
Q. Abarr, P. Allison, J. Ammerman Yebra +47
The Payload for Ultrahigh Energy Observations (PUEO) long-duration balloon experiment is designed to have world-leading sensitivity to ultrahigh-energy neutrinos at energies above…
Constraints on the Diffuse Flux of Ultra-High Energy Neutrinos from Four Years of Askaryan Radio Array Data in Two Stations
ARA Collaboration, P. Allison, S. Archambault +71
The Askaryan Radio Array (ARA) is an ultra-high energy (UHE, eV) neutrino detector designed to observe neutrinos by searching for the radio waves emitted by the relativi…
Observation of Radar Echoes From High-Energy Particle Cascades
S. Prohira, K. D. de Vries, P. Allison +15
We report the observation of radar echoes from the ionization trails of high-energy particle cascades. These data were taken at the SLAC National Accelerator Laboratory, where the…
Long-baseline horizontal radio-frequency transmission through polar ice
P. Allison, S. Archambault, J. J. Beatty +63
We report on analysis of englacial radio-frequency (RF) pulser data received over horizontal baselines of 1--5 km, based on broadcasts from two sets of transmitters deployed to dep…
