Collimation and Radiative Deceleration of Jets in TeV AGNs
Amir Levinson, Omer Bromberg
We consider some implications of the rapid X-ray and TeV variability observed in M87 and the TeV blazars. We outline a model for jet focusing and demonstrate that modest radiative…
Relativistic Photon Mediated Shocks
Amir Levinson, Omer Bromberg
A system of equations governing the structure of a steady, relativistic radiation dominated shock is derived, starting from the general form of the transfer equation obeyed by the…
On the Origin of Rapid Flares in TeV Blazars
Amir Levinson
The rapid variability of the VHE emission reported for some TeV blazars implies Doppler factors well in excess of those inferred from superluminal motions and unification schemes.…
Phenomenology of Gamma-Ray Jets
Amir Levinson
We discuss some phenomenological aspects of -ray emitting jets. In particular, we present calculations of the -sphere and -sphere for various target photon fields, and emp…
Structure and Nuclear Composition of General Relativistic, Magnetohydrodynamic Outflows from Neutrino-Cooled Disks
Yudith Barzilay, Amir Levinson
We compute the structure and degree of neutronization of general relativistic magnetohydrodynamic (GRMHD) outflows originating from the inner region of neutrino-cooled disks. We co…
Gamma Ray and Neutrino Emission as a Probe of Relativistic Jets
Amir Levinson
Constraints on the dynamics, dissipation, and production of VHE neutrinos in relativistic jets are derived using opacity calculations and VHE -ray observations. In particular, i…
