43. Radio measurements of air showers with the IceCube-Gen2 surface prototype station at the Pierre Auger Observatory

Stef Verpoest (University of Delaware)

6/9/26, 9:00 AM

The design of the IceCube-Gen2 observatory, proposed as a next-generation extension of IceCube, includes a surface array consisting of scintillators and radio antennas. In addition to several such detectors already deployed at IceCube’s surface array at the South Pole, a prototype station including 3 SKALA antennas has been operating at the Pierre Auger Observatory for several years. This...

36. First Air-Shower Measurements with the Auger Radio Infill SKALA Extension (ARISE)

Carmen Merx (KIT/IAP)

6/9/26, 9:15 AM

The Auger Radio Infill SKALA Extension (ARISE) was installed in 2025 at the Pierre Auger Observatory to detect the radio emission in the band of 50-350 MHz of near-vertical cosmic-ray air showers at energies of 10s to 100s PeV. The array comprises 18 SKALA-2 antennas deployed around one of the surface-detector stations of the 433m infill array (SD-433), which provides the trigger for ARISE. We...

6. Determining the absolute energy scale of cosmic-ray measurements with AERA

Tim Huege (KIT)

6/9/26, 9:30 AM

Determining the absolute energy scale in cosmic-ray observations is both challenging and of fundamental importance. We show that radio measurements of extensive air showers with the Auger Engineering Radio Array, combined with per-event CoREAS simulations, enable an accurate calibration of the cosmic-ray energy scale between 3 x $10^{17}$ eV and several $10^{18}$ eV. To ensure an accurate...

50. Searching for Cosmic Rays in the Deep Antennas of RNO-G

Bryan Hendricks

6/9/26, 9:45 AM

The Radio Neutrino Observatory in Greenland (RNO-G) is designed to detect neutrinos at ultra-high energies, exploiting Askaryan emission in ice. However, this emission is not exclusive to neutrinos. Cosmic ray air shower cores can continue cascading in the ice, producing Askaryan emission that in limited cases cannot be rejected by simple vetoes. Rather than being purely a background concern,...

20. Observation of In-ice Askaryan Radiation from High-Energy Cosmic Rays

Kaeli Hughes (The Ohio State University)

6/9/26, 10:00 AM

The Askaryan Radio Array (ARA) is a neutrino detector located at the South Pole that searches for radio emission from ultra high energy neutrino interactions within Antarctic ice. While ARA is primarily a neutrino detector, it is also sensitive to Askaryan emission from cosmic ray air showers that develop at the surface of the ice. ARA consists of five autonomous stations, each with vertical...

44. Evidences for Combined Geomagnetic and Askaryan Emission in a CR Candidate Event

Kenneth Couberly (University of Kansas)

6/9/26, 10:15 AM

The Askaryan Radio Array (ARA) is a radio neutrino detector designed primarily to detect neutrinos with energies above 10 PeV. In addition to neutrinos, ARA is also sensitive to radio emission from cosmic-ray(CR)–induced air showers. Detection of these emissions can support detector calibration, improve the detection capabilities of the detector, and help model CRs as a background for neutrino...

34. The Low-Frequency Instrument for the Payload for Ultrahigh Energy Observations (PUEO)

Yuchieh Ku (Pennsylvania State University)

6/9/26, 11:00 AM

The Payload for Ultrahigh Energy Observations (PUEO) is a long-duration balloon experiment designed to detect ultra-high-energy (UHE) neutrinos with energies above 1 EeV. The instrument consists of a Main Instrument (MI) mounted on the payload and a Low-Frequency (LF) instrument deployed beneath the payload. The LF instrument comprises eight sinuous antennas operating in the 50–500 MHz band,...

33. The Flight of the PUEO

Cosmin Deaconu (University of Chicago)

6/9/26, 11:15 AM

The Payload for Ultrahigh Energy Observations (PUEO), a NASA long duration balloon payload seeking to detect ultrahigh energy particles using the radio technique, flew over Antarctica for 23 days this Austral summer. This talk will discuss the performance of PUEO during the flight, covering the trigger, attitude systems, background and telemetry systems. I will also present the latest progress...
