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…
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…
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…
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…
