High resolution observations of NGC1275 with a four-element intercontinental radio interferometer

Abstract

The radio nucleus of NGC1275 (3C84) is found to consist of three apparently stationary centres of emission extending over 0.006″ (3pc) along position angle −9°. One or more of these centres have changed their intensity or size in the last 3 yr. A preferential direction of alignment of both the small scale and large scale radio features as well as the optical features suggests a common cause of alignment operating over linear distances from a few pc to > 100 kpc.
