Recent analyses of the muon content in extensive air showers produced by cosmic rays above 100 PeV reveal an excess in the data in comparison with Monte Carlo (MC) simulations. These differences point out problems of the high-energy hadronic interaction models, which are not yet understood. In this regard, measurements of different experiments are important, since they could provide some clues...

Unveiling the still unknown ultra high energy astrophysical sources in the sky greatly benefits of a multimessenger approach, combining information from charged cosmic rays with the one carried by photons and neutrinos. However, implementing this approach necessitates a thorough understanding of the microphysics processes shaping the spectra and energy distribution across these species. In...

The hadron production in the simulation of extensive air showers is a long standing problem and the origin of large uncertainties in the reconstruction of the mass of the high energy primary cosmic rays. Hadronic interaction models re-tuned after early LHC data give more consistent results among each other compared to the first generation of models, but still can't reproduce extended air...

Gamma-ray bursts (GRBs) are high-energy events that release isotropic energy on the order of $10^{48}$ - $10^{55}$ erg. They are classified into long or short bursts depending on their observed duration. Long GRBs have a duration ($t_{90}$) greater than 2 seconds, and their progenitors are associated with the collapse of massive stars (collapsars).
Distances are only known for a small...

Gamma Ray Burst (GRBs) are brief and highly energetic gamma ray explosions, which can be classified into short and long bursts based on their duration. Long GRBs last more than two seconds, and are believed to originate from the collapse of massive stars.
