Simulation of combined radio and radar signals at the Radar Echo Telescope for Cosmic Rays
K. Nivedita, I. Loudon, J. Loonen +29
To explore neutrino astronomy at high energies (> 10 PeV), the Radar Echo Telescope for Cosmic Rays (RET-CR) was developed to assess the feasibility of a radar technique for detect…
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, sn…
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…
Macroscopic approach to the radar echo scatter from high-energy particle cascades
E. Huesca Santiago, K. D. de Vries, P. Allison +28
To probe the cosmic particle flux at the highest energies, large volumes of dense material like ice have to be monitored. This can be achieved by exploiting the radio signal. In th…
Analysis of a Tau Neutrino Origin for the Near-Horizon Air Shower Events Observed by the Fourth Flight of the Antarctic Impulsive Transient Antenna (ANITA)
R. Prechelt, S. A. Wissel, A. Romero-Wolf +65
We study in detail the sensitivity of the Antarctic Impulsive Transient Antenna (ANITA) to possible point source fluxes detected via -lepton-induced air showers. This inve…
A search for ultrahigh-energy neutrinos associated with astrophysical sources using the third flight of ANITA
C. Deaconu, L. Batten, P. Allison +60
The ANtarctic Impulsive Transient Antenna (ANITA) long-duration balloon experiment is sensitive to interactions of ultra high-energy (E > 10^{18} eV) neutrinos in the Antarctic ice…
Experimental tests of sub-surface reflectors as an explanation for the ANITA anomalous events
D. Smith, D. Z. Besson, C. Deaconu +31
The balloon-borne ANITA experiment is designed to detect ultra-high energy neutrinos via radio emissions produced by an in-ice shower. Although initially purposed for interactions…
Unusual Near-horizon Cosmic-ray-like Events Observed by ANITA-IV
ANITA Collaboration, P. W. Gorham, A. Ludwig +57
ANITA's fourth long-duration balloon flight in late 2016 detected 29 cosmic-ray (CR)-like events on a background of anthropogenic events. CRs are mainly seen…
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…
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…
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…
Constraints on the ultra-high energy cosmic neutrino flux from the fourth flight of ANITA
P. W. Gorham, P. Allison, O. Banerjee +57
The ANtarctic Impulsive Transient Antenna (ANITA) NASA long-duration balloon payload completed its fourth flight in December 2016, after 28 days of flight time. ANITA is sensitive…
A comprehensive analysis of anomalous ANITA events disfavors a diffuse tau-neutrino flux origin
A. Romero-Wolf, S. A. Wissel, H. Schoorlemmer +60
Recently, the ANITA collaboration reported on two upward-going extensive air shower events consistent with a primary particle that emerges from the surface of the ice. These events…
Upward-Pointing Cosmic-Ray-like Events Observed with ANITA
Andres Romero-Wolf, P. W. Gorham, J. Nam +73
These proceedings address a recent publication by the ANITA collaboration of four upward- pointing cosmic-ray-like events observed in the first flight of ANITA. Three of these even…
Observation of an Unusual Upward-going Cosmic-ray-like Event in the Third Flight of ANITA
P. W. Gorham, B. Rotter, P. Allison +60
We report on an upward traveling, radio-detected cosmic-ray-like impulsive event with characteristics closely matching an extensive air shower. This event, observed in the third fl…
Constraints on the diffuse high-energy neutrino flux from the third flight of ANITA
P. W. Gorham, P. Allison, O. Banerjee +57
The Antarctic Impulsive Transient Antenna (ANITA), a NASA long-duration balloon payload, searches for radio emission from interactions of ultra-high-energy neutrinos in polar ice.…
