Abstract Ultra-high-energy neutrinos serve as messengers of some the highest energy astrophysical environments. Given that are neutral and only interact via weak interactions, can emerge from sources, traverse astronomical distances, point back to their origins. Their interactions require large target volumes for neutrino detection. Using Earth a converter, terrestrial, sub-orbital, satellite-based instruments able detect signals neutrino-induced extensive air showers. In this paper, we...
After nearly 20 years of data-taking, the measurements made with Pierre Auger Observatory represent largest collection ultra-high-energy cosmic ray (UHECR) data so far assembled from a single instrument. Exploring this set led to deeper understanding UHECR flux and many surprises. In particular, studies aiming investigate leverage mass composition UHECRs have played an important role in empowering discovery. This contribution will present overview analyses primary carried out during first...
After a successful kick-off meeting in 2021. two workshops 2022 and 2023 on the future Global Cosmic-Ray Observatory (GCOS) focused mainly straw man design of detector science possibilities for astro- particle physics. About 100 participants gathered in-person hybrid panel discussions. In this report, we summarize these discussions, present preliminary straw-man GCOS collect short write-ups flash talks given during focus sessions.
The Global Cosmic-ray Observatory (GCOS) is a proposed large-scale observatory for studying ultra-high-energy cosmic particles, including rays (UHECRs), photons, and neutrinos. Its primary goal to characterise the properties of highest-energy particles in Nature with unprecedented accuracy, identify their elusive sources. With an aperture at least ten-fold larger than existing observatories, this next-generation facility should start operating after 2030, when present-day detectors will...

A scan over a subset used select optimal threshold energy $10^{18.7}$ eV splitting $|b| =...
Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) gravitational waves. Already today, these probes give access to fundamental physics not available by any other means, helping elucidate the underlying theory that completes Standard Model. The last decade has witnessed a revolution exciting discoveries such as detection high-energy neutrinos scope for major developments in next decades is dramatic, we detail this report.

The Pierre Auger Observatory (Auger) and the Telescope Array Project (TA) are two largest ultra-high-energy cosmic ray observatories in world. They operate Southern Northern hemispheres, respectively, at similar latitudes but with different surface detector (SD) designs. This difference design changes their sensitivity to various components of extensive air showers. over-arching goal Auger@TA working group is cross-calibrate SD arrays order identify or rule out systematic causes for apparent...

Understanding the nature of transition from Galactic to extragalactic cosmic rays (GCRs and EGCRs) has become especially challenging in light recent spectral composition data. contributions appear be disfavoured at energies beyond ''second knee'' where becomes lighter. At same time, a dominant EGCR contribution ''2nd appears unlikely. As result, measured flux region cannot easily accounted for. With model-dependence proposed extensions both contributions, deeper understanding CR propagation,...
