Identified with the elliptical galaxy NGC 6109 in the double cluster
Zw 1615.8+3505. The extended source at the bottom of our image is NGC 6107, the
central galaxy in the other clump of the cluster. X-ray emission from the
cluster has been mapped by
Feretti et al. (1995).
At higher resolution
(O'Dea & Owen 1985) a well
collimated jet points along the tail, while there is a discrete blob on
the opposite side of the core. In our image all these structure form the
elongated peak at the
south end of the source. The situation is very similar to that in the head of
4C11.71. The most likely explanation is that the
galaxy is travelling through the cluster roughly in the direction of one of the
jets, which is stalled to create the upstream blob, while the other jet
survives as it flows downstream.
Note that several unrelated background sources are seen through the
extended radio tail. Also, the noise is worse in the corners of this image
because of the fall-off of sensitivity at the edges of the VLA primary beam.
