Structure of the inner jet of OJ 287 VLBA data at 15 GHz in a super-resolution mode

Abstract

In this work we show the results obtained from the VLBA data at 15 GHz of OJ 287 in the super-resolution mode. The data showed a jet configuration in the form of "fork" where superluminal components emerge via stationary components at the northwest and the southeast close to the core to form parallel trajectories along the southwest direction in the plane of the sky. This agrees with a source structure of an extended, broad morphology of OJ 287.
