Relativistic Outflows in Active Galactic Nuclei
N. Vlahakis, A. Konigl
There are observational indications that relativistic outflows in AGNs are accelerated over distances that far exceed the scale of the central engine. Examples include the radio ga…
Large-scale magnetic fields in GRB outflows: acceleration, collimation, and neutron decoupling
N. Vlahakis, A. Konigl
Using ideal magnetohydrodynamics we examine an outflow from a disk surrounding a stellar-mass compact object. We demonstrate that the magnetic acceleration is efficient (of the ord…
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…
Neutron-Rich Hydromagnetic Outflows in Gamma-Ray Burst Sources
Nektarios Vlahakis, Fang Peng, Arieh Konigl
We demonstrate that ``hot'' MHD outflows from neutron-rich black-hole debris disks can significantly alleviate the baryon-loading problem in gamma-ray burst (GRB) sources. We argue…
Relativistic Magnetohydrodynamics with Application to Gamma-Ray Burst Outflows: II. Semianalytic Super-Alfvenic Solutions
Nektarios Vlahakis, Arieh Konigl
We present exact radially self-similar solutions of special-relativistic magnetohydrodynamics representing ``hot'' super-Alfvenic outflows from strongly magnetized, rotating compac…
Relativistic Magnetohydrodynamics with Application to Gamma-Ray Burst Outflows: I. Theory and Semianalytic Trans-Alfvenic Solutions
Nektarios Vlahakis, Arieh Konigl
We present a general formulation of special-relativistic magnetohydrodynamics and derive exact radially self-similar solutions for axisymmetric outflows from strongly magnetized, r…
