| Abstract : | Hybrid radio morphology (HYMOR) sources are the touchstone for addressing the Fanaroff-Riley (FR) divide in AGN jets as they exhibit an FR type I (FRI) jet on one side of the core and an FR type II (FRII) on the other. I will present results from the first polarisation-sensitive uGMRT observations at 694 MHz of the well-known radio-intermediate (RI), hybrid morphology (HYMOR) and broad absorption line (BAL) quasar, PG1004+130. These observations reveal extensive polarised emission in the lobes and jets of this source. Our total intensity images suggest that PG1004+130 is a restarted source. Based on our polarised intensity images as well as archival Chandra X-ray data, we find indications that both the previous jet episode and the present one are from an FRII source. We discuss the implications of this finding on our understanding of the FR divide. |
