Sensitivity of the As-Built Askaryan Radio Array to Ultra-High Energy Neutrinos
ARA Collaboration, N. Alden, S. Ali +71
The Askaryan Radio Array (ARA) is an ultra-high energy (UHE) neutrino observatory designed to detect the impulsive radio waves produced by relativistic particle cascades in the Ant…

Observation of In-ice Askaryan Radiation from High-Energy Cosmic Rays
ARA Collaboration, N. Alden, S. Ali +74
We present the first experimental evidence for in-ice Askaryan radiation -- coherent charge-excess radio emission -- from high-energy particle cascades developing in the Antarctic…

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…
