Single source scenario describing the very end of the cosmic ray energy spectrum [PDF]

open access: yesEPJ Web of Conferences, 2023
The energy spectrum of cosmic rays is steeply falling with a suppression of the flux at the highest energies caused by energy losses during propagation or by reaching the maximum energy of cosmic accelerators.

Latest results from the searches for ultra-high-energy photons and neutrinos at the Pierre Auger Observatory

open access: yesInternational Conference on Rebooting Computing, 2023
The Pierre Auger Observatory is the largest air-shower experiment in the world, offering an unprecedented exposure not only to ultra-high-energy (UHE, 𝐸 > 10 17 eV) cosmic rays, but also to UHE neutral particles, specifically photons and neutrinos. Since

A brief history of image sensors in the optical

open access: yesAstronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023
Image sensors, most notably the Charge Coupled Device (CCD), have revolutionized observational astronomy as perhaps the most important innovation after photography. Since the 50th anniversary of the invention of the CCD has passed in 2019, it is time to review the development of detectors for the visible wavelength range, starting with the discovery of

Probing hadronic interactions with measurements from the Pierre Auger Observatory

open access: yesSciPost Physics Proceedings, 2022
The Pierre Auger Observatory is the largest facility in the world to study ultra-high-energy cosmic rays. It has a hybrid detection technique that combines the observation of the longitudinal development of extensive air showers and the measurement of

Update on the searches for anisotropies in UHECR arrival directions with the Pierre Auger Observatory and the Telescope Array

open access: yesInternational Conference on Rebooting Computing, 2023
The origin of ultra-high-energy cosmic rays (UHECRs), particles from outer space with energies 𝐸 ≥ 1 EeV, is still unknown, though the near-isotropy of their arrival direction distribution excludes a dominant Galactic contribution, and interactions with ...

Big Science Collaborations; Lessons for Global Governance and Leadership

open access: yesGlobal Policy, Volume 12, Issue 1, Page 66-80, February 2021., 2021
Abstract Big Science communities have been remarkably effective in evolving complex processes and mechanisms to enable international collaborations. Major powers such as the People's Republic of China, Russia and the USA, who are fierce rivals in other domains, form lasting alliances.

An update on the arrival direction studies made with data from the Pierre Auger Observatory

open access: yesInternational Conference on Rebooting Computing, 2023
The search for anisotropies in the arrival directions of ultra-high-energy cosmic rays plays a key role in the efforts to understand their origin.

Constraints on metastable superheavy dark matter coupled to sterile neutrinos with the Pierre Auger Observatory [PDF]

open access: yesPhysical Review D, 2023
Dark matter particles could be superheavy, provided their lifetime is much longer than the age of the universe. Using the sensitivity of the Pierre Auger Observatory to ultra-high energy neutrinos and photons, we constrain a specific extension of the ...

Particle Physics with the Pierre Auger Observatory

open access: yesSciPost Physics Proceedings, 2022
The Pierre Auger Observatory is the largest extensive air shower detector. Based on a hybrid system, this experiment measures the longitudinal shower development and the particles at the ground. This detection system allows the extraction of the p-air
