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…
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…
Magnetic Burial in Millisecond Magnetars and Late GRB Afterglow Signatures
Nissim Fraija, Cristian Giovanni Bernal, Antonio Galván +2
Millisecond magnetars, one of the potential candidates for the central engine of Gamma-ray bursts (GRBs), can experience significant magnetic field enhancement shortly after their…
