We present VLBI and MERLIN data at 1.66 and 4.99 GHz on the central component coincident with the nucleus of the giant radio galaxy, 3C236. The nuclear radio structure is composed of two complexes of emission which are resolved on scales…

The HST/STIS ultraviolet image of the FR I radio galaxy 3C270 shows the presence of a jet-like structure emerging from the position of the nucleus. This feature, which represents the first jet-like component ever detected in the UV in a…

NGC4261 (3C270) is an elliptical galaxy containing a 300-parsec scale nuclear disk of gas and dust imaged by the Hubble Space Telescope (HST), around a central supermassive black hole. Previous VLBI observations of NGC4261 revealed a gap in…
