Scientific paper

The authors present 73-cm radio continuum observations of NGC 1275 with an angular resolution of 1.2 arcsec. The observations show an unresolved core together with two weaker knots which are interpreted as a radio jet in position angle ≡160°. This jet may be associated with an optical filament in PA 172° which aligns precisely with the 2.8-cm VLBI jet and shows an unusually high velocity-gradient. The authors suggest that this filament could be formed by the cooling of gas entrained into a beam in PA 172°. If this hypothesis is correct, then the radio knots are displaced 2→3 arcsec (≡1 kpc) from the axis of the beam.
