Polarization From A Radially Stratified Off-Axis GRB Outflow
A. C. Caligula do E. S. Pedreira, N. Fraija, A. Galvan-Gamez +5
While the dominant radiation mechanism gamma-ray bursts (GRBs) remains a question of debate, synchrotron emission is one of the foremost candidates to describe the multi-wavelength…
Afterglow Polarization from Off-Axis GRB Jets
A. C. Caligula do E. S. Pedreira, N. Fraija, A. Galvan-Gamez +5
As we further our studies on Gamma-ray bursts (GRBs), both on theoretical models and observational tools, more and more options begin to open for exploration of its physical proper…
Exploring the Early Afterglow Polarization of GRB 190829A
A. C. Caligula do E. S. Pedreira, N. Fraija, S. Dichiara +5
The GRB 190829A has been widely studied due to its nature and the high energy emission presented. Due to the detection of a very-high-energy component by the High Energy Stereoscop…
Radio interferometric imaging of RS Oph bipolar ejecta for the 2021 nova outburst
U. Munari, M. Giroletti, B. Marcote +5
The recurrent nova and symbiotic binary RS Oph erupted again in August 2021 for its eighth known outburst. As part of a multi-epoch and frequency campaign, we observed RS Oph 34 da…
GRB Afterglow of the Sub-relativistic Materials with Energy Injection
N. Fraija, B. Betancourt Kamenetskaia, A. Galvan-Gamez +5
Sub-relativistic materials launched during the merger of binary compact objects and the core-collapse of massive stars acquire velocity structures when expanding in a stratified en…
Modeling Gamma-ray burst Afterglow observations with an Off-axis Jet emission
Nissim Fraija, Antonio Galvan-Gamez, Boris Betancourt Kamenetskaia +5
Gamma-ray bursts (GRBs) are fascinating extragalactic objects. They represent a fantastic opportunity to investigate unique properties not exhibited in other sources. Multi-wavelen…
