Likelihood reconstruction for radio detectors of neutrinos and cosmic rays

Anonymous, Christian Gläser, T. Glüsenkamp, Ayça Özçelikkale et autres

Ultra-high-energy neutrinos and cosmic rays are excellent probes of astroparticle physics phenomena. For astroparticle physics analyses, robust and accurate reconstruction of signal parameters such as arrival direction and energy is essential. Radio detection is an established detector concept explored by many observatories; …

Event reconstruction for radio-based in-ice neutrino detectors with neural posterior estimation

Nils Heyer, Christian Gläser, T. Glüsenkamp, Martin Langgård Ravn

Abstract The detection of ultra-high-energy (UHE) neutrinos in the EeV range is the goal of current and future in-ice radio arrays at the South Pole and in Greenland. Here, we present a deep neural network that can reconstruct the main neutrino properties …

Identification and denoising of radio signals from cosmic-ray air showers using convolutional neural networks

Rasha U. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

Radio pulses generated by cosmic-ray air showers can be used to reconstruct key properties like the energy and depth of the electromagnetic component of cosmic-ray air showers. Radio detection threshold, influenced by natural and anthropogenic radio background, can be reduced through various …

Improved measurements of the TeV-PeV extragalactic neutrino spectrum from joint analyses of IceCube tracks and cascades

Rasha U. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

The IceCube South Pole Neutrino Observatory has discovered the presence of a diffuse astrophysical neutrino flux at energies of TeV and beyond using neutrino induced muon tracks and cascade events from neutrino interactions. We present two analyses sensitive to neutrino events in …

Probing neutrino emission at GeV energies from compact binary mergers with the IceCube Neutrino Observatory

R. Abbasi, M. Ackermann, J. S. Adams, S. K. Agarwalla et autres

The advent of multi-messenger astronomy has allowed for new types of source searches by neutrino detectors. We present the results of the search for 0.5-100 GeV astrophysical neutrinos detected with IceCube and emitted from compact binary mergers detected by the LIGO, Virgo, …

Probing the firn refractive index profile using antenna response

J. A. Aguilar, Nathaniel Alden, P. Allison, O. Botner et autres

Abstract 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 approximately 35 km 2 . Since the RNO-G experimental sensitivity depends on the radio-frequency properties of the …

All-sky Neutrino Point-source Search with IceCube Combined Track and Cascade Data

Rasha U. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

Abstract Despite extensive efforts, discovery of high-energy astrophysical neutrino sources remains elusive. We present an event-level simultaneous maximum likelihood analysis of tracks and cascades using IceCube data collected from 2008 April 6 to 2022 May 23 to search the whole sky for …

Seasonal variations of the atmospheric muon neutrino spectrum measured with IceCube

Rasha U. Abbasi, M. Ackermann, J. Adams, Sanjib Kumar Agarwalla et autres

Abstract This study presents an analysis of seasonal variations in the atmospheric muon neutrino flux, using 11.3 years of data from the IceCube Neutrino Observatory. By leveraging a novel spectral unfolding method, we explore the energy range from 125 GeV to 10 …

Optimization pipeline for in-ice radio neutrino detectors

Martin Langgård Ravn, Philipp Pilar, Christian Gläser, Niklas Wahlström et autres

In-ice radio detection of neutrinos is a rapidly growing field and a promising technique for discovering the predicted but yet unobserved ultra-high-energy astrophysical neutrino flux. With the ongoing construction of the Radio Neutrino Observatory in Greenland (RNO-G) and the planned radio extension …

Radio emission from airplanes as observed with RNO-G

S. Agarwal, J. A. Aguilar, Nathaniel Alden, S. Ali et autres

Abstract 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 signals and define a procedure to extract a clean set of impulsive signals. These signals are highly …
