On the nature of radiation from the nucleus of a CD galaxy A0779

Abstract

An attempt is made to detect synchrotron radiation from the nucleus of a CD galaxy A-0779 through polarization studies. We have detected a high degree of polarization (up to 9 percent in ultraviolet) with a bimodal distribution in the position angle; this can be thought due to two distinct components, one from the nucleus and the other from the galaxy. The position angle in ultraviolet coincides with the direction of radio jet direction as seen by VLBI observations, indicating relativistic beaming from the nucleus of the galaxy
