Backward emission in quasars

Abstract

In the local Doppler theory of quasars the lack of observed blueshifts can be explained if quasars, ejected at high velocities from active galactic nuclei, radiate predominantly in a backward cone. An astrophysical single exhaust model has been proposed which not only explains why quasars emit radiation in the backward direction, but may also be able to account for some of their morphological features.
