Anomalous horizontal track-like events at the HAWC observatory: candidate neutrino-induced charged leptons from the Pico de Orizaba volcano

Hermes León Vargas, Andrés Sandoval

Two track-like events with exceptionally large charge deposits, pointing back to the region of maximum overburden ( km.w.e.) of the Pico de Orizaba volcano, were reported by t…

Hadronic Clues in Quasars Caught by Fermi-LAT

Antonio Galván, Nissim Fraija, Edilberto Aguilar-Ruiz +3

This work explores whether hadronic processes could be responsible for the high-energy emission seen in quasars identified by the Large Area Telescope (LAT) instrument aboard the F…

Late-afterglow Emission from a Quasi-spherical Outflow in a stratified environment

Nissim Fraija, Boris Betancourt-Kamenetskaia, Antonio Galván +7

Gamma-ray bursts (GRBs) are cosmic events occurring at large distances beyond our galaxy. They provide a unique opportunity to study electromagnetic patterns not seen elsewhere. Wh…

Search for seasonal variations of the horizontal muon rate with the HAWC observatory

Cindy Castellón, Hermes León Vargas

The High-Altitude Water Cherenkov (HAWC) observatory was designed to study gamma-ray sources in the energy range between a few hundred GeV up to few hundred TeV. It is composed of…

Piritakua: the atmosphere as a high-energy physics laboratory

Hermes León Vargas, Antonio Galván, Andrés Sandoval +3

The atmosphere provides a large set of experimental conditions on which cosmic-ray induced high-energy hadron interactions can take place. These conditions include: sudden changes…
