HALCA images of the young radio source 1413+135 Original Research Article

The radio source 1413+135 is remarkable for a number of reasons; 1) it is 18 times more variable at 8 GHz cm wavelengths than at 2.3 GHz, 2) it is one of the few (∼4) sources where radio absorption lines of H1, CO, HCN and other molecules (Wiklind and Combes 1994 A&A 286:L9) have been detected, and 3) it appears to be a young radio source (< 104 years, Perlman et al. 1996, A. J. 111:1839.), which has not yet produced kilo parsec scale radio lobes. Our HALCA+VLBA image have resolved compact jet components near the core, and future observations will measure the angular velocity of these components.
