Example of the detection of tidal tails

Example of the detection of tidal tails (labelled as T1, T2, and T3), a bridge, and dust in the interacting system between the PRG PKS 0347+05 (center) and a quasar. The dark halos around unresolved objects, like the quasar, in this and other figures are a consequence of the unsharp-mask processing of the image.
