    • Constraining AGN duty cycle in the cool-core cluster MS 0735.6+7421 with LOFAR data 

      Biava, Nadia; Brienza, Marisa; Bonafede, Annalisa; Gitti, Myriam; Bonnassieux, Etienne; Harwood, Jeremy; Edge, Alastair C.; Riseley, Christopher J.; Vantyghem, Adrian (2021-06-25)
      MS 0735.6+7421 is a galaxy cluster which hosts a central radio galaxy with a very steep spectrum, produced by one of the most powerful known jetted active galactic nuclei (AGN). The radio plasma, ejected at nearly light ...

    • The resolved jet of 3C 273 at 150 MHz : Sub-arcsecond imaging with the LOFAR international baselines 

      Harwood, Jeremy J.; Mooney, Sean; Morabito, Leah K.; Quinn, John; Sweijen, Frits; Groeneveld, Christian; Bonnassieux, Etienne; Kappes, Alexander; Moldon, Javier (2022-02-01)
      Context. Since its discovery in 1963, 3C 273 has become one of the most widely studied quasars with investigations spanning the electromagnetic spectrum. While much has therefore been discovered about this historically ...

    • Spectral analysis of spatially-resolved 3C295 (sub-arcsecond resolution) with the International LOFAR Telescope 

      Bonnassieux, Etienne; Sweijen, Frits; Brienza, Marisa; Rajpurohit, Kamlesh; Riseley, Christopher John; Bonafede, Annalisa; Jackson, Neal; Morabito, Leah K.; Brunetti, Gianfranco; Harwood, Jeremy; Kappes, Alex; Rottgering, Huub J.; Tasse, Cyril; Weeren, Reinout van (2022-02-25)
      3C295 is a bright, compact steep spectrum source with a well-studied integrated radio spectral energy distribution (SED) from 132 MHz to 15 GHz. However, spatially resolved spectral studies have been limited due to a lack ...
