127. The Askaryan Radio Array: latest results and ongoing work.

Toscano, Simona

6/7/22, 9:15 AM

The Askaryan Radio Array (ARA) is searching for high energy neutrinos (>10 PeV) from the cosmos using clusters of antennas buried under the South Pole ice sheet at a maximum depth of 200 m. ARA is looking at the radio Cherenkov emission generated when neutrinos interact with the surrounding medium. The array consists of 5 radio stations, each of them monitoring an independent portion of the...

78. Results from the ARIANNA high-energy neutrino detector

Glaser, Christian (Uppsala University)

6/7/22, 9:35 AM

The ARIANNA in-ice radio detector explores the detection of UHE neutrinos with shallow detector stations on the Ross Ice Shelf and the South Pole. I will present recent results that lay the foundation for future large-scale experiments. I will show a limit on the UHE neutrino flux derived from ARIANNA data, measurements of the more abundant air showers, results from in-situ measurement...

130. The Payload for Ultrahigh Energy Observations (PUEO)

Cummings, Austin Lee (Pennsylvania State University)

6/7/22, 10:00 AM

PUEO is a long duration balloon experiment which will launch in 2024 from Antarctica that builds on the successes of the previous flights of the ANITA experiment in order to probe the cosmic neutrino flux above EeV energies. PUEO, like ANITA, seeks to measure coherent radio emission in the form of Askaryan emission from neutrino interactions inside the Antarctic ice sheet and both geomagnetic...

91. The Radio Neutrino Observatory Greenland (RNO-G): Status Update

Hallmann, Steffen (DESY)

6/7/22, 10:20 AM

In 2021, the first three stations of the Radio Neutrino Observatory in Greenland (RNO-G) have been installed and started data-taking. The deployment of additional stations is currently ongoing. RNO-G is an in-ice detector with the prospect to the first detection of a neutrino shower beyond $\sim$10 PeV via the Askaryan emission. With a projected 90% CL upper limit below $E^2\Phi\sim\, 10^{-8}$...

83. Triboelectric events in RNO-G

Cataldo, Maddalena

6/7/22, 10:40 AM

The Radio Neutrino Observatory Greenland (RNO-G) has the scientific purpose to observe ultra-high energy cosmogenic neutrinos through in-ice radio detection. The remoteness of polar experiments makes sure that anthropogenic sources of background are naturally lowered. However, other sources of noise are present and have to be studied in order to reach rejection rates necessary to unambiguously...

82. Searching for air showers with RNO-G

Henrichs, Jakob (DESY)

6/7/22, 10:55 AM

The Radio Neutrino Observatory – Greenland (RNO-G) is an in-ice
neutrino detector, using the detection of radio emission to target the first
measurement of neutrinos beyond PeV energies. In total 35 stations are
planned for the detector, resulting in a detection volume of around 100
km${}^3$. Each of these stations is equipped with deep antennas embedded $\sim$100 m into the ice and...

132. Deep Learning for the Classification and Recovery of Cosmic-Ray Radio Signals Against Background Measured at the South Pole

Coleman, Alan

6/7/22, 11:10 AM

A major hurdle in radio detection of cosmic-ray air showers is the continuous background that contaminates the signals. In this work, we use deep learning techniques to mitigate the effect of background by training two convolutional neural networks (CNNs). One network is used to distinguish the radio traces containing air-shower signals from those traces containing only background. The other...
