2. Simulating an Imaging Atmospheric Radio Telescope

Anne Timmermans (Max-Planck-Institut für Kernphysik)

6/10/26, 9:00 AM

Currently imaging atmospheric Cherenkov telescopes provide the most precise TeV gamma-ray measurements, but are limited to a duty cycle of about 15% due to their reliance on clear, moonless nights. Building on this idea, a novel imaging atmospheric radio telescope could combine radio detection with powerful imaging-based reconstruction while enabling observations with a duty cycle close to...

76. Radio Detection of Earth-Skimming Tau Neutrinos: A Comparison of Frequency Bands and Antenna Designs

Felix Schlüter (Free University Brussels (ULB))

6/10/26, 9:15 AM

We present a simulation study of radio detection of Earth-skimming tau neutrinos produced by tau leptons
emerging from mountain ranges. Using CoREAS simulations of nearly horizontal extensive air showers, we
investigate the radio emission characteristics and effective detection areas across multiple frequency bands,
ranging from 30 - 80 MHz to the C-band at 3.4 - 4.2 GHz. Each frequency...

54. The case for studying anomalous showers with the Square Kilometre Array

Stijn Buitink (VUB)

6/10/26, 9:30 AM

High-energy hadronic interactions are an important source of uncertainty in studies of the mass composition of cosmic rays. To make progress we either need to better constrain hadronic interaction parameters or find model-independent mass-sensitive parameters. Both of these options can be pursued by studying anomalous air showers in which one or more secondary hadrons carry a significant...

71. Millisecond radio signal generation enabling simulation-based multi-parameter reconstruction of ultra-high-energy cosmic rays

Arsène Ferrière (CEA-LIST, LPNHE)

6/10/26, 9:45 AM

In recent years, radio detection of ultra-high-energy cosmic rays (UHECRs), with energies above 1018 eV, has become an established technique. Radio emissions can be simulated with high accuracy using Monte Carlo codes such as ZHAireS and CoREAS, but these simulations are computationally intensive.
In this work, we present a machine-learning-based emulator that reproduces radio signal...

41. Radio emission from particle distributions in extensive air showers

Juan Ammerman-Yebra (Radboud University)

6/10/26, 10:00 AM

Radio emission simulation from particles showers is one of the most intense CPU processes in ultra high energy astroparticle physics. A detailed study of particle distributions in air showers together with their implications for radio emission will be shown. Based on the results from these studies, a new cost-effective calculation of radio emission from particle distributions will be presented...

4. Efficient Time-Domain Modeling of Geomagnetic and Askaryan Radiation from Air Showers

Carmen Pavon-Souto

6/10/26, 10:15 AM

We introduce a semi-analytical framework to compute coherent pulses from extensive air showers initiated by cosmic rays inspired in previous work on modeling Askaryan radiation in dense media (ARVZ model). The predictions are benchmarked against detailed Monte Carlo simulations performed with the ZHAireS package. Our method accurately reconstructs the vector potential in the time domain and,...

10. Radio emission in complex media simulations with Corsika8

Dominik Baack (TU Dortmund)

6/10/26, 10:30 AM

The CORSIKA8 simulation framework, a successor of the well-known Monte Carlo air-shower simulation CORSIKA7, is a state-of-the-art implementation and testbed for the simulation of particle cascades from air to dense media. With its modular architecture, not only standard cascade simulation is possible, but a variety of additional mechanisms can be utilized. The Radio module, as one of the...

45. Simulation of Deep Cosmic Rays with FAERIE framework for RNO-G

Prof. David Seckel (University of Delaware)

6/10/26, 11:15 AM

The Radio Neutrino Observatory in Greenland (RNO-G) aims to detect ultra-high-energy neutrinos via Askaryan radiation, yet in-ice cosmic-ray (CR) air shower cores produce similar radio signatures that represent a significant background. While the FAERIE framework allows for high-precision modeling of these signals, its default computational requirements, which often require beyond 3,000 CPU...

63. Radar Signal Properties from Neutrino-Induced Particle Cascades

Isha Loudon

6/10/26, 11:30 AM

The RET experiment aims to utilise radar techniques to spot ultrahigh energy neutrinos. This is achieved by targeting ionisation trails left in the wake of in-ice neutrino-induced cascades: in an ice volume illuminated with a radar system, the trail will reflect incident radio waves, allowing the neutrino to be detected via surrounding receivers. The reflected radio forms an echo signal, from...

14. What can we learn from radio emission from ice-impacting air showers?

Cosmin Deaconu (University of Chicago)

6/10/26, 11:45 AM

In-ice askaryan emission from cosmic ray air showers impacting into glacial ice has now been definitively observed. In this talk I will explore what can be measured about cosmic rays, hadronic models, Askaryan emission, and radio propagation in the interaction medium by studying this class of events in current experiments.

72. Sensitivity of the Askaryan Radio Array to Ultra-High Energy Neutrinos

Marco Muzio

6/10/26, 12:00 PM

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 Antarctic glacial ice. ARA has five independent stations which have been taking data for over a decade. Here we present a revised calculation of ARA’s sensitivity to UHE neutrinos based on a time-dependent simulation of...

67. Modelling In-Ice Secondary Cosmic Ray Cascades

Isha Loudon

6/10/26, 12:15 PM

Cosmic-Ray (CR) air-showers impacting a high-altitude ice sheet impart a significant fraction of energy into the ice, forming a dense cascade below the ice surface. Above PeV energies, these secondary CR cascades are the target of the RET-CR experiment, and their associated radio-Askaryan emission makes them a background source in radio-neutrino detectors, such as ARA and RNO-G. This process...

31. Likelihood-Based Reconstruction for Radio Detector Experiments

Martin Ravn (Uppsala University)

6/10/26, 12:30 PM

An essential part of any analysis using radio detector data is robust and accurate reconstruction of the physical parameters governing the observed signals. However, most current reconstruction methods ignore bin-to-bin noise correlations, which limits reconstruction resolution and prevents reliable event-by-event uncertainty estimates. In this talk, we present a likelihood-based approach to...

37. Semi-analytical parametrization of in-ice radio signals from cosmic ray particle cascades

Simon Chiche (Université Libre de Bruxelles)

6/10/26, 12:45 PM

Ultra-high-energy neutrino detectors such as ARA and RNO-G rely on radio antennas deployed in ice to detect particle cascades. In this context, the in-ice radio emission from cosmic-ray-induced particle cascades constitutes both a major background and a valuable calibration source. Accurate modeling of this emission currently relies on detailed Monte Carlo simulations, such as FAERIE, which...
