    • The spectral structure and energetics of powerful radio sources 

      Harwood, J. J.; Hardcastle, M J.; Croston, J. H.; Stroe, A.; Morganti, R.; Orru, E. (2014-04-29)
      Determining the energy spectrum of an electron population can give key insights into the underlying physics of a radio source; however, the lack of high resolution, broad-bandwidth observations has left many ambiguities ...

    • Studying the late evolution of a radio-loud AGN in a galaxy group with LOFAR 

      Savini, F.; Bonafede, A.; Brüggen, M.; Wilber, A.; Harwood, J. J.; Murgia, M.; Shimwell, T.; Rafferty, D.; Shulevski, A.; Brienza, M.; Hardcastle, M. J.; Morganti, R.; Röttgering, H.; Clarke, A. O.; de Gasperin, F.; van Weeren, R.; Best, P. N.; Botteon, A.; Brunetti, G.; Cassano, R. (2018-03-11)
      Feedback by radio-loud active galactic nuclei (AGNs) in galaxy groups is not fully understood. Open questions include the duty cycle of theAGN, the spatial extent of the radio lobes, the effect they have on the intragroup ...
