74. First data and performance of the Radio Detector of the Pierre Auger Observatory

Jörg Hörandel (Radboud University Nijmegen)

6/8/26, 1:10 PM

The Radio Detector of the Pierre Auger Observatory measures radio emission from extensive air showers in the frequency range of 30–80 MHz. Covering an area of 3000 km², it constitutes the largest installation dedicated to the detection of cosmic particles, including charged cosmic rays, gamma rays, and neutrinos. Commissioning was completed at the end of 2024, and the radio antennas now...

15. Science Goals and Instrumentation of the Auger Radio Infill SKALA Extension (ARISE)

Frank Schröder (University of Delaware and Karlsruhe Institute of Technology (KIT))

6/8/26, 1:30 PM

The Auger Radio Infill SKALA Extension (ARISE) at the Pierre Auger Observatory in Argentina measures cosmic-ray air showers in the energy region around 100 PeV. ARISE is comprised of 18 SKALA-2 antennas featuring two polarization channels each, deployed in 2025 within 100 m from a surface detector station in the enhancement area of the Pierre Auger Observatory. This area of the surface array...

49. Radio self-triggering in GRANDProto300

Pengxiong Ma (Purple mountain observatory,CAS)

6/8/26, 1:50 PM

GRANDProto300 (GP300) is the ongoing pathfinder array for the next-generation GRAND (Giant Radio Array for Neutrino Detection) ultra-high-energy astroparticle observatory. Since April of 2025, GP300 has operated as a 20 km² array of 65 detection units in northwest China. This location was strategically selected for its radio-quiet environment, which is essential for the array’s radio...

65. Air-shower detection with the surface antennas at the IceCube Neutrino Observatory

Megha Venugopal (Karlsruhe Institute of Technology)

6/8/26, 2:10 PM

IceTop is the surface air-shower array of the IceCube Neutrino Observatory measuring cosmic rays in the PeV – EeV energy range. Additional detectors of scintillators and antennas are to be deployed in the IceTop footprint as part of the Surface Array Enhancement. The scintillators aim to reduce the energy threshold to the TeV regime and the antennas provide information on mass-sensitive...

27. Detection of Scintillator-Triggered Cosmic Rays with the BEACON Prototype

Andrew Zeolla (Institut d'Astrophysique de Paris)

6/8/26, 2:30 PM

The Beamforming Elevated Array for COsmic Neutrinos (BEACON) is an ultrahigh energy neutrino detector concept consisting of hundreds of phased radio arrays placed on mountaintops, searching for the geomagnetic emission of up-going extensive air showers created by Earth-skimming tau neutrinos. A prototype of the BEACON concept, consisting of a single phased radio array, operated in the White...

39. The Payload for Ultrahigh Energy Observations Design and Science Reach

Stephanie Wissel (Penn State)

6/8/26, 2:50 PM

The Payload for Ultrahigh Energy Observations (PUEO) is a NASA Long Duration Balloon-borne mission that flew over Antarctica for 23 days starting in December 2025. PUEO is sensitive to neutrinos interactions in the Antarctic ice that result in Askaryan emission and geomagnetic emission from cosmic rays and tau neutrinos. These neutrinos may arise from cosmogenic neutrinos produced during the...

18. The Radio Neutrino Observatory in Greenland (RNO-G): Status Update and Recent Results

Kaeli Hughes (The Ohio State University)

6/8/26, 3:40 PM

The Radio Neutrino Observatory in Greenland (RNO-G) is a next-generation radio detector designed to observe ultra-high-energy (UHE) neutrinos above 10^16 eV via the Askaryan effect. RNO-G currently consists of eight autonomous stations, with a total of 35 stations planned for construction over the next few years. Each RNO-G station includes a set of deep antennas deployed on strings up to a...

66. The First Array-Wide Diffuse Flux Search for UHE Neutrinos with ARA

Marco Muzio

6/8/26, 4:00 PM

The Askaryan Radio Array (ARA) is an ultra-high energy (UHE) neutrino detector at the South Pole that searches for impulsive broadband radio signals from neutrino-induced particle showers in glacial ice. ARA comprises five autonomous stations deployed at the South Pole, each instrumented with antennas deployed up to 200 meters below the ice surface and sensitive to both vertically and...

60. The Radar Echo Telescope

Krijn de Vries (Vrije Universiteit Brussel - IIHE)

6/8/26, 4:20 PM

The Radar Echo Telescope (RET) experiment aims to probe the cosmic neutrino flux at >PeV energies using radar. We present our latest results, discussing the RET-CR pathfinder experiment deployed at Summit Camp, Greenland. The RET-CR experiment aims to detect the in-ice continuation of high-energy cosmic-ray-induced particle cascades hitting the ~3km altitude Greenlandic ice sheet. The in-air...
