Emission from Large-scale Jets in Quasars
We consider the emission processes in the large-scale jets of powerful quasars based on the results obtained with the VLA, Spitzer, Hubble, and Chandra. We show that two well-known jets, 3C 273 and PKS 1136−135, have two distinct spectral components on large-scales: (1) the low-energy (LE) synchrotron spectrum extending from radio to infrared, and (2) the high-energy (HE) component arising from...
متن کاملRotation-Measures across Parsec-scale Jets of FRI radio galaxies
We present the results of a parsec-scale polarization study of three FRI radio galaxies – 3C66B, 3C78 and 3C264 – obtained with the Very Long Baseline Array at 5, 8 and 15 GHz. Parsec-scale polarization has been detected in a large number of beamed radio-loud active galactic nuclei, but in only a handful of the relatively unbeamed radio galaxies. We report here the detection of parsec-scale pol...
متن کاملOn Multiwavelength Emission of Large-Scale Quasar Jets
We discuss morphological properties of the large-scale jets in powerful radio sources, which are now observed at radio, optical and X-ray frequencies, in order to determine the origin of their X-ray radiation and the nature of the particle acceleration responsible for their multiwavelength emission. We show that modeling knots of the these objects as stationary regions of energy dissipation wit...
متن کاملOn Multiwavelength Emission and Morphology of Large-Scale Quasar Jets
We propose, that the knots of the large-scale jets in powerful radio sources represent moving and separate portions of the jet matter, with the excess kinetic power. This can explain many morphological properties of quasar jets — like high knot-tointerknot brightness contrasts, frequency-independent knot profiles and almost universal extents of the knot regions — independently of the exact emis...
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...
