    • 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 ...

      Rottgering, Huub; Afonso, Jose; Barthel, Peter; Batejat, Fabien; Best, Philip; Bonafede, Annalisa; Brueggen, Marcus; Brunetti, Gianfranco; Chyzy, Krzysztof; Conway, John; De Gasperin, Francesco; Ferrari, Chiara; Haverkorn, Marijke; Heald, George; Hoeft, Matthias; Jackson, Neal; Jarvis, M.J.; Ker, Louise; Lehnert, Matt; Macario, Giulia; McKean, John; Miley, George; Morganti, Raffaella; Oosterloo, Tom; Orru, Emanuela; Pizzo, Roberto; Rafferty, David; Shulevski, Alexander; Tasse, Cyril; van Bemmel, Ilse; van der Tol, Bas; van Weeren, Reinout; Verheijen, Marc; White, Glenn; Wise, Michael (2011-12)
      At very low frequencies, the new pan-European radio telescope LOFAR is opening the last unexplored window of the electromagnetic spectrum for astrophysical studies. The revolutionary APERTIF-phased arrays that are about ...

    • 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 ...
