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…
Stability and structure of analytical MHD jet formation models with a finite outer disk radius
Matthias Stute, Kanaris Tsinganos, Nektarios Vlahakis +2
(Abridged) Finite radius accretion disks are a strong candidate for launching astrophysical jets from their inner parts and disk-winds are considered as the basic component of such…
Resistive jet simulations extending radially self-similar magnetohydrodynamic models
Miljenko Cemeljic, Jose Gracia, Nektarios Vlahakis +1
Numerical simulations with self-similar initial and boundary conditions provide a link between theoretical and numerical investigations of jet dynamics. We perform axisymmetric res…
Two-component jet simulations: I. Topological stability of analytical MHD outflow solutions
T. Matsakos, K. Tsinganos, N. Vlahakis +3
Observations of collimated outflows in young stellar objects indicate that several features of the jets can be understood by adopting the picture of a two-component outflow, wherei…
Magnetic acceleration of relativistic AGN jets
S. S. Komissarov, M. V. Barkov, N. Vlahakis +1
We present numerical simulations of axisymmetric, magnetically driven relativistic jets. To eliminate the dissipative effects induced by a free boundary with an ambient medium we a…
Nonradial and nonpolytropic astrophysical outflows VIII. A GRMHD generalization for relativistic jets
Z. Meliani, C. Sauty, N. Vlahakis +2
Steady axisymmetric outflows originating at the hot coronal magnetosphere of a Schwarzschild black hole and surrounding accretion disk are studied in the framework of general relat…
