A Heavy-Metal Scenario of Ultra-High-Energy Cosmic Rays
Jakub VÃcha, Alena Bakalová, Ana L. Müller +2
The mass composition of ultra-high-energy cosmic rays is an open problem in astroparticle physics. It is usually inferred from the depth of the shower maximum (Xmax) of cosmic-ray…

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…

Azimuthal fluctuations and number of muons at the ground in muon-depleted proton air showers at PeV energies
A. Bakalová, R. Conceição, L. Gibilisco +4
Muon counting is an effective strategy for discriminating between gamma and hadron-initiated air showers. However, their detection, which requires shielded detectors, is highly exp…
