Maps using relativistic time delay
| The angle of view will affect the radio morphology because different parts of the flow will be subject to Doppler beaming depending on the orientation of the local flow to the observer: the same jet may appear very differently at different viewing angles. Compare Map 1 and Map 7. These both use the c_s model, viewed at 15° and 25° respectively. The peak intensity of Map 1 is about 50% of Map 7, but the morphology is also different. This difference is not simply due to foreshortening, as there are features in Map 7 not present in Map 1. For example the knotty bright spots at [-6,-8] and [-10,-2] in Map 7 do not appear in Map 1. These features are the result of the change in observer angle changing the part of the flow that is beamed. More shocked cocoon material is beamed at 25° than at 15°. The bright spots in Map 7 originate in this part of the flow. Looking at Map 13, 85°, we note that its peak intensity is only 8% of Map 1's peak. At this angle the structure resembles the renderings of the hydrodynamic flow. The bright spot to the left is the bow shock, and the cocoon can be traced out in the faint trailing emission. | |
