1112.2898 (Wen-Po Liu)
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.
