| 内容記述 | Observations of 13 X-ray selected BL Lacertae objects (X-BL Lacs) from the HEAO-1 Large Area Sky Survey have been obtained with the Very Large Array. These X-BL Lacs are Fanaroff-Riley I radio sources, and are less core-dominated than traditional radio selected BL Lacs (R-BL Lacs). The radio properties are consistent with a 'unified scheme' connecting BL Lacs with FR I radio galaxies, where X-BL Lacs are oriented at larger angles to the line-of-sight than R-BL Lacs. However, the X-ray emission does not appear to be as strongly relativistically beamed as the radio and may be completely unbeamed. |
