Radio morphologies at 5.5 GHz of the MRCR-SUMSS sample. The size and orientation of the restored beam is given in the bottom left of each panel. The red box indicates the size and location of the SINFONI maps presented in Fig. 2. For NVSS J144932−385657, given the short observation time of this source and hence the deformed beam, we also present its 4.8 GHz observations from Bryant et al. (2009a), who observed a part of their sample at 4.8 GHz and 8.64 GHz.
