Synchrotron self-Compton Reverse Shock in Energy-Injection and Radiative Scenarios
Fraija Nissim, Betancourt-Kamenetskaia Boris, Galván Antonio +1
Gamma-ray bursts (GRBs) are among the most energetic extragalactic transients, providing a unique laboratory to investigate the physical origin of the diverse morphologies observed…
Deep Newtonian Afterglows: Theoretical Light Curves for Quasi-spherical Outflows
Nissim Fraija, Boris Betancourt-Kamenetskaia, Antonio Galván +1
We investigate late-time gamma-ray burst (GRB) afterglows produced by quasi-spherical outflows propagating into a stratified circumburst medium during the deep Newtonian phase. Sub…
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…
Redshift Classification of Optical Gamma-Ray Bursts using Supervised Learning
Milind Sarkar, Maria Giovanna Dainotti, Nikita S. Khatiya +9
Gamma-ray bursts (GRBs) are among the most luminous explosions in the Universe and serve as powerful probes of the early cosmos. However, the rapid fading of their afterglows and t…
Variation of Microphysical Parameters in Reverse-shock Scenario
Nissim Fraija, Boris Betancourt-Kamenetskaia, Antonio Galván +1
Gamma-ray bursts (GRBs), among the most compelling astrophysical phenomena, are potential candidates for exploring the evolution of energy distribution among magnetic fields and pa…
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…
