The variation of spectral index across the radio galaxy 3C 452
Recent maps of the radio galaxy 3C 452 made with the Cambridge One-Mile telescope at 408 and 1407 MHz have been compared with published maps at 2.7 and 5.0 GHz made with the same telescope. The spectral index is found to increase from 0.7 at the outer ends of the source to ≈ 1.7 at the centre. This...

Summary: | Recent maps of the radio galaxy 3C 452 made with the Cambridge One-Mile telescope at 408 and 1407 MHz have been compared with published maps at 2.7 and 5.0 GHz made with the same telescope. The spectral index is found to increase from 0.7 at the outer ends of the source to ≈ 1.7 at the centre. This behaviour is probably caused by synchrotron losses in the radiating electrons and the observations are consistent with a simple model based on this assumption. |
