The Proto-Magnetar Model for Gamma-Ray Bursts
B. D. Metzger, D. Giannios, T. A. Thompson +2
Long duration Gamma-Ray Bursts (GRBs) originate from the core collapse of massive stars, but the identity of the central engine remains elusive. Previous work has shown that rapidl…
GRB 050502B optical afterglow: a jet break at high redshift
P. Afonso, J. Greiner, E. Pian +9
Aims: GRB 050502B is well known for the very bright flare displayed in its X-ray light curve. Despite extensive studies, however, the optical light curve has never been discussed a…
UHECRs from magnetic reconnection in relativistic jets
Dimitrios Giannios
Ultra-high energy cosmic rays (UHECRs) may be produced in active galactic nuclei (AGN) or gamma-ray burst (GRB) jets. I argue that magnetic reconnection in jets can accelerate UHEC…
Radiative Properties of Reconnection-Powered Minijets in Blazars
Krzysztof Nalewajko, Dimitrios Giannios, Mitchell C. Begelman +2
We construct a numerical model of emission from minijets, localized flows driven by magnetic reconnection inside Poynting-flux-dominated jets proposed to explain the ultrafast vari…
Multiwavelength afterglow light curves from magnetized GRB flows
P. Mimica, D. Giannios, M. A. Aloy
We use high-resolution relativistic MHD simulations coupled with a radiative transfer code to compute multiwavelength afterglow light curves of magnetized ejecta of gamma-ray burst…
Unveiling the origin of X-ray flares in Gamma-Ray Bursts
G. Chincarini, J. Mao, R. Margutti +10
We present an updated catalog of 113 X-ray flares detected by Swift in the ~33% of the X-ray afterglows of Gamma-Ray Bursts (GRB). 43 flares have a measured redshift. For the first…
