Stellar physics at sub-nanoradian angular resolution

P. Batista, J. Biteau, C. Carlile +36

Many stars -- if they could be imaged with enough angular resolution -- would exhibit features expected from theory but not possible to extract from spectra. We may group these by…

The distribution of ultra-high-energy cosmic rays along the supergalactic plane measured at the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +364

Ultra-high-energy cosmic rays are known to be mainly of extragalactic origin, and their propagation is limited by energy losses, so their arrival directions are expected to correla…

Radio Measurements of the Depth of Air-Shower Maximum at the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +372

The Auger Engineering Radio Array (AERA), part of the Pierre Auger Observatory, is currently the largest array of radio antenna stations deployed for the detection of cosmic rays,…

Demonstrating Agreement between Radio and Fluorescence Measurements of the Depth of Maximum of Extensive Air Showers at the Pierre Auger Observatory

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +372

We show, for the first time, radio measurements of the depth of shower maximum () of air showers induced by cosmic rays that are compared to measurements of the estab…

Design and characterization of the Flat-Field Calibration of the NectarCAM Camera

Anastasiia Mikhno, Federica Bradascio, Jonathan Biteau +13

The NectarCAM flat-field flasher is a calibration device designed for the camera that will equip the Medium-Sized Telescopes (MSTs) of the northern site of the Cherenkov Telescope…

Ideas and Requirements for the Global Cosmic-Ray Observatory (GCOS)

Markus Ahlers, Ingo Allekotte, Jaime Alvarez-Muniz +136

After a successful kick-off meeting in 2021. two workshops in 2022 and 2023 on the future Global Cosmic-Ray Observatory (GCOS) focused mainly on a straw man design of the detector…
