The short wide angle tail radio source in NGC 4874.

Radio maps at 1.5 and 4.9 GHz are presented of the radio source associated with NGC 4874, one of the two dominant galaxies of the Coma cluster. This radio source of the WAT type, has a very small linear size and is all contained within the optical galaxy. The existence of a very short WAT source implies that either the role of interstellar medium in bending the radio structure is not negligible, or the transition between interstellar and intergalactic medium occurs very close to the center of the galaxy, or other mechanisms are responsible for the wide angle tail phenomenon.
