Radial and vertical angular momentum transport in protostellar discs
Raquel Salmeron, Arieh Königl, Mark Wardle
Angular momentum in protostellar discs can be transported either radially, through turbulence induced by the magnetorotational instability (MRI), or vertically, through the torque…
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…
Two-Component Jet Models of Gamma-Ray Burst Sources
Fang Peng, Arieh Konigl, Jonathan Granot
Recent observational and theoretical studies have raised the possibility that the collimated outflows in gamma-ray burst (GRB) sources have two distinct components: a narrow (openi…
The prompt X-ray emission of GRB011211: possible evidence of a transient absorption feature
F. Frontera, L. Amati, J. J. M. in 't Zand +10
We report on observation results of the prompt X- and gamma-ray emission from GRB011211. This event was detected with the Gamma-Ray Burst Monitor and one of the Wide Field Cameras…
Magnetic Acceleration and Collimation of Gamma-Ray Burst Jets
A. Konigl
Exact semianalytic solutions for GRB outflows were recently derived using the equations of special-relativistic ideal MHD (see Vlahakis & Konigl in these Proceedings for a summary)…
Magnetic Driving of Relativistic Outflows in Active Galactic Nuclei. I. Interpretation of Parsec-Scale Accelerations
Nektarios Vlahakis, Arieh Konigl
There is growing evidence that relativistic jets in active galactic nuclei undergo extended (parsec-scale) acceleration. We argue that, contrary to some suggestions in the literatu…
