Magnetic acceleration of ultra-relativistic jets in gamma-ray burst sources
Serguei Komissarov, Nektarios Vlahakis, Arieh Konigl +1
We present a relativistic-MHD numerical study of axisymmetric, magnetically driven jets with parameters applicable to gamma-ray burst (GRB) flows. We also present analytic expressi…
Central engines of Gamma Ray Bursts. Magnetic mechanism in the collapsar model
Maxim V. Barkov, Serguei S. Komissarov
In this study we explore the magnetic mechanism of hypernovae and relativistic jets of long duration gamma ray bursts within the collapsar scenario. This is an extension of our ear…
Hyper-accreting tori of Gamma Ray Bursters
M. V. Barkov
We present numerical simulations of axisymmetric magnetised massive tori around rotating black holes taking into account the energy losses due to emission of neutrinos. A realistic…
Magnetic acceleration of ultra-relativistic GRB and AGN jets
Maxim V. Barkov, Serguei S. Komissarov
We present numerical simulations of cold, axisymmetric, magnetically driven relativistic outflows. The outflows are initially sub-Alfvénic and Poynting flux-dominated, with total--…
Stellar explosions powered by the Blandford-Znajek mechanism
M. V. Barkov, S. S. Komissarov
In this letter we briefly describe the first results of our numerical study on the possibility of magnetic origin of relativistic jets of long duration gamma ray bursters within th…
Magnetar-energized supernova explosions and GRB-jets
S. S. Komissarov, M. V. Barkov
In this paper we report on the early evolution of core-collapse supernova explosion following the birth of a magnetar with the dipolar magnetic field of B=10^{15}G and the rotation…
