On the Relation between Agn Gamma-ray Emission and Parsec-scale Radio Jets
We have compared the radio emission from a sample of parsec-scale AGN jets as measured by the VLBA at 15 GHz, with their associated γ-ray properties that are reported in the Fermi LAT 3-month bright source list. We find in our radio-selected sample that the γ-ray photon flux correlates well with the quasi-simultaneously measured compact radio flux density. The LAT-detected jets in our radio-sel...
متن کاملA Model for the Offsets between X-ray and Radio Emission from Large Scale AGN Jets
We investigate apparent internal structure of kiloparsec scale jets of AGNs arising from the energy dependent cooling of accelerated electrons and light travel time effect for relativistically moving sources. Using a simple cylindrical shell model, we find that the offsets between the peaks of X-ray, optical and radio brightness distributions observed for many cases are basically explained with...
متن کاملParsec-scale Jets in Extragalactic Radio Sources1
Observations of parsec-scale radio jets associated with active galactic nuclei are reviewed, with a particular emphasis on high-luminosity core-dominated sources where the most detailed information on individual objects exists. Extensive imaging surveys with very long baseline interferometry (VLBI) have made possible a morphologic classification of compact radio sources and systematic studies o...
متن کاملSynchrotron emission from relativistic parsec – scale jets
We developed theory of particle acceleration inside the relativistic rotating electronpositron force–free jet with spiral magnetic field. We considered perturbation of stationary magnetic field structure and found that acceleration takes place in the regions where the Alfvén resonant condition with the eigenmodes in the jet is fulfilled, i.e. where the local Alfvén speed is equal to the phase s...
متن کاملRelativistic parsec–scale jets: II. Synchrotron emission
We calculate the optically thin synchrotron emission of fast electrons and positrons in a spiral stationary magnetic field and a radial electric field of a rotating relativistic strongly magnetized force–free jet consisting of electron-positron pair plasma. The magnetic field has a helical structure with a uniform axial component and a toroidal component that is maximal inside the jet and decre...
