Modeling the refractive index profile n(z) of polar ice for ultra-high energy neutrino experiments
S. Ali, P. Allison, S. Archambault +67
We have developed an in-situ index of refraction profile n(z) for cold polar ice, using the transit times of radio signals broadcast from an englacial transmitter to 2-5 km distant…
Calibration and Physics with ARA Station 1: A Unique Askaryan Radio Array Detector
M. F. H Seikh, D. Z. Besson, S. Ali +70
The Askaryan Radio Array Station 1 (A1), the first among five autonomous stations deployed for the ARA experiment at the South Pole, is a unique ultra-high energy neutrino (UHEN) d…
Triboelectric Backgrounds to radio-based UHE Neutrino Exeperiments
J. A. Aguilar, A. Anker, P. Allison +114
The proposed IceCube-Gen2 (ICG2) seeks to instrument ~500 sq. km of Antarctic ice near the geographic South Pole with radio antennas, in order to observe the highest energy (E>1 Ee…
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…
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…
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…
Antarctic Radio Frequency Albedo and Implications for Cosmic Ray Reconstruction
D. Z. Besson, J. Stockham, M. Sullivan +42
From an elevation of ~38 km, the balloon-borne ANtarctic Impulsive Transient Antenna (ANITA) is designed to detect the up-coming radio frequency (RF) signal resulting from a sub-su…
A next generation Ultra-Fast Flash Observatory (UFFO-100) for IR/optical observations of the rise phase of gamma-ray bursts
B. Grossan, I. H. Park, S. Ahmad +39
The Swift Gamma-ray Burst (GRB) observatory responds to GRB triggers with optical observations in ~ 100 s, but cannot respond faster than ~ 60 s. While some ground-based telescopes…
Detection and Imaging of the Crab Nebula with the Nuclear Compton Telescope
M. S. Bandstra, E. C. Bellm, S. E. Boggs +17
The Nuclear Compton Telescope (NCT) is a balloon-borne Compton telescope designed for the study of astrophysical sources in the soft gamma-ray regime (200 keV--20 MeV). NCT's ten h…
Design and Initial Performance of the Askaryan Radio Array Prototype EeV Neutrino Detector at the South Pole
P. Allison, J. Auffenberg, R. Bard +45
We report on studies of the viability and sensitivity of the Askaryan Radio Array (ARA), a new initiative to develop a Teraton-scale ultra-high energy neutrino detector in deep, ra…
