Design and Performance of an Interferometric Trigger Array for Radio Detection of High-Energy Neutrinos
P. Allison, S. Archambault, R. Bard +69
Ultra-high energy neutrinos are detectable through impulsive radio signals generated through interactions in dense media, such as ice. Subsurface in-ice radio arrays are a promisin…
First Constraints on the Ultra-High Energy Neutrino Flux from a Prototype Station of the Askaryan Radio Array
ARA Collaboration, P. Allison, J. Auffenberg +48
The Askaryan Radio Array (ARA) is an ultra-high energy ( eV) cosmic neutrino detector in phased construction near the South Pole. ARA searches for radio Cherenkov emissio…
Modelling ice birefringence and oblique radio wave propagation for neutrino detection at the South Pole
T. M. Jordan, D. Z. Besson, I. Kravchenko +4
The Askaryan Radio Array (ARA) experiment at the South Pole is designed to detect high-energy neutrinos which, via in-ice interactions, produce coherent radiation at frequencies up…
Observation of Reconstructable Radio Emission Coincident with an X-Class Solar Flare in the Askaryan Radio Array Prototype Station
P. Allison, S. Archambault, J. Auffenberg +74
The Askaryan Radio Array (ARA) reports an observation of radio emission coincident with the "Valentine's Day" solar flare on Feb. 15, 2011 in the prototype "Testbed" st…
The Next-Generation Radio Neutrino Observatory -- Multi-Messenger Neutrino Astrophysics at Extreme Energies
J. A. Aguilar, P. Allison, S. Archambault +58
RNO is the mid-scale discovery instrument designed to make the first observation of neutrinos from the cosmos at extreme energies, with sensitivity well beyond current instrument c…
Measurement of the real dielectric permittivity epsilon_r of glacial ice
P. Allison, S. Archambault, J. Auffenberg +66
Using data collected by the Askaryan Radio Array (ARA) experiment at the South Pole, we have used long-baseline propagation of radio-frequency signals to extract information on the…
Performance of two Askaryan Radio Array stations and first results in the search for ultra-high energy neutrinos
ARA Collaboration, P. Allison, R. Bard +64
Ultra-high energy neutrinos are interesting messenger particles since, if detected, they can transmit exclusive information about ultra-high energy processes in the Universe. These…
Long-baseline horizontal radio-frequency transmission through polar ice
