| Abstract: | High-resolution radio observations are presented of the flat-spectrum, 1-arcsec double radio source 1830- 211. Optical CCD imaging in the I-band shows an ~22 - mag object coincident with the radio source position. We find that the unique nature of 1830 - 211 may be understood in terms of gravitational imaging of a background compact flat-spectrum radio source by a foreground galaxy. A lensing model is presented for the compact as well as the extended emission features, and possible tests to confirm the lens hypothesis are outlined. |
