Held in Tuscaloosa, Alabama: 19-23 September 1995.. Also archived in: arXiv:astro-ph/9512097 v1 14 Dec 1995. The emission lines in the active galaxy IRAS 0421+0400 show a dramatic ( 900 kms−1) increase in the velocity spread at the position of radio hotspots which are located at the beginning of extended radio lobes . We study a model which explains this phenomenon as the result of a jet emerging through the boundary between the interstellar and intergalactic medium . A similar scenario has previously been suggested as an explanation for wide angle tail radio sources (WAT’s) . Based on our model, we simulate the longslit spectra of these regions and compare the results with the observations and find that it can explain most of the details in the observed longslit spectra.
