Helical Jet in the Gravitationally Lensed Blazar
Recent radio VLBI observations of the complex gravitationally lensed system PKS1830-211 have thrown up some questions with regard to the processes occuring at the heart of the blazar source at a redshift of 2.51, which is viewed almost straight down the jet axis. This work links, by a model of a helical jet tracked by ballistically ejected plasmons from a precessing nozzle, observations on the ...

متن کاملThe Core of a Blazar Jet
The nature of the bright upstream end of jets as seen in VLBI images, known as the core, is difficult to specify because it is only weakly resolved on the images. Here the author discusses evidence indicating that the core is either where the optical depth is of order unity or a standing shock somewhat farther downstream. The jet at this point is turbulent, causing the polarization to be low an...
متن کاملThe Jet-Disk Connection and Blazar Unification
We discuss the relation between the power carried by relativistic jets and the nuclear power provided by accretion, for a group of blazars including FSRQs and BL Lac objects. They are characterized by good quality broad band X-ray data provided by the Beppo SAX satellite. The jet powers are estimated using physical parameters determined from uniformly modelling their spectral energy distributio...
متن کاملEstimating jet power in proton blazar models
We discuss the various contributions to the jet luminosity in proton blazar models of active galactic nuclei and describe a method of estimating the jet luminosity from the observed spectral energy distribution (SED) and the fitted model parameters. We apply this to a synchrotron proton blazar (SPB) model for Markarian 501.
