A Data-driven Heavy-Metal Scenario for Ultra-High-Energy Cosmic Rays
Jakub VÃcha, Alena Bakalová, Ana L. Müller +2
The mass composition of ultra-high-energy cosmic rays (UHECRs) is usually inferred from the depth of the shower maximum () of cosmic-ray showers, which is only ambigu…
On the Origin of Ultra-high-energy Cosmic Rays Assuming a Heavy Mass Composition
Alena Bakalová, Ana Laura Müller, Jakub VÃcha
Recent studies, supported by updated hadronic interaction models, suggest that the mass composition of ultra-high-energy cosmic rays may be heavier than previously assumed. This ha…
Consequences of a Heavy-Metal Scenario of Ultra-High-Energy Cosmic Rays
Jakub VÃcha, Alena Bakalová, Olena Tkachenko +2
We assume an extreme scenario, in which the arriving cosmic rays are composed of only iron nuclei at energies above , while allowing a fre…
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…
