Zappala` ( Istituto di Radioastronomia del CNR di Noto (SR), Istituto di Radioastronomia del CNR di Bologna, Dipartimento di Astronomia Universita` di Bologna, Osservatorio Ast | | Abstract: | We have observed 28 sources selected from the 1Jy sample of BL Lac objects (Stickel et al. 1991) with the Very Large Array (VLA) in A, B and D configurations at 1.36, 1.66 and 4.85 GHz, and/or with the Westerbork Synthesis Radio Telescope (WSRT) at 1.40 GHz. In this paper we present high sensitivity images at arcsecond resolution of the 18 objects showing extended structure in our images, and of another source from the FIRST (Faint Images of the Radio Sky at Twenty-cm) survey (Becker et al. 1995). In general our high sensitivity images reveal an amount of extended emission larger than previously reported. In some objects the luminosity of the extended structure is comparable with that of FR~II radio sources. A future paper will be devoted to the interpretation of these results. | | Source: | arXiv, astro-ph/9910209 | | Services: | Forum | Review | PDF | Favorites | |
