Determination of the intrinsic velocity field in the M87 jet
A new method to estimate the Doppler beaming factor of relativistic large-scale jet regions is presented. It is based on multiwaveband fitting to radio-to-X-ray continua with synchrotron spectrumExpand
AN ASYMMETRICAL SYNCHROTRON MODEL FOR KNOTS IN THE 3C 273 JET
To interpret the emission of knots in the 3C 273 jet from radio to X-rays, we propose a synchrotron model in which, owing to the shock compression effect, the injection spectra from a shock into theExpand
A Non-Mainstream Viewpoint on Apparent Superluminal Phenomena in AGN Jet
The group velocity of light in material around the AGN jet is acquiescently one (c as a unit), but this is only a hypothesis. Here, we re-derive apparent superluminal and Doppler formulas for theExpand
Determination of the Doppler factor of relativistic beams in radio active galactic nuclei. (I) 3C 273
Abstract There are shortcomings in the present available method of determining the Doppler factor δ based on a uniform model of synchrotron self-Compton mechanism and linking the observed fluxes atExpand
AN HOURGLASS MODEL FOR THE FLARE OF HST-1 IN M87
To explain the multi-wavelength light curves (from radio to X-ray) of HST-1 in the M87 jet, we propose an hourglass model that is a modified two-zone system of Tavecchio & Ghisellini (hereafterExpand
