1112.2898 (Wen-Po Liu)

A Non-mainstream Viewpoint on the Apparent Superluminal Phenomena in AGN jet    [PDF]

Wen-Po Liu
The material around an AGN jet is generally assumed to be plasma which of refractive index is 1. In this letter, we propose a non-mainstream viewpoint which considers that the equivalent refractive index of the surrounding medium in an AGN jet is not equal to 1. Applying this viewpoint to the beaming model of AGN jet, we could get a lower true velocity and a higher Doppler factor than the classic model, which may reduce the singularity of AGN and its jet. At present, this letter contains only the germ of an idea and the physical meaning of the equivalent refractive index needs to be further studied.
