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…

Probing the Firn Refractive Index Profile Using Antenna Response

S. Agarwal, J. A. Aguilar, N. Alden +70

The Radio Neutrino Observatory-Greenland (RNO-G, at Summit Station) experiment comprises an extensive fat-dipole antenna array deployed into ice boreholes over an eventual area of…

Radio emission from airplanes as observed with RNO-G

G Collaboration, S. Agarwal, J. A. Aguilar +79

This paper describes how intentional and unintentional radio emission from airplanes is recorded with the Radio Neutrino Observatory Greenland (RNO-G). We characterize the received…

Askaryan Radio Array: searching for the highest energy neutrinos

Mohammad Ful Hossain Seikh

Searches for ultra-high energy ( PeV) cosmogenic and astrophysical neutrinos (UHENs) have been conducted by several experiments over the last two decades. The Askaryan…
