    • Finding Rare Quasars: VLA Snapshot Continuum Survey of FRI Quasar Candidates Selected from the LOFAR Two-Metre Sky Survey (LoTSS) 

      Gürkan, Gülay; Croston, Judith; Hardcastle, Martin J.; Mahatma, Vijay; Mingo, Beatriz; Williams, Wendy L. (2021-12-22)
      The radiative and jet power in active galactic nuclei is generated by accretion of material on to supermassive galactic-centre black holes. For quasars, where the radiative power is by definition very high, objects with ...

    • The Host Galaxies of Hybrid Morphology Radio Sources 

      Stroe, Andra; Catlett, Victoria; Harwood, Jeremy J.; Vernstrom, Tessa; Mingo, Beatriz (2022-12-16)
      Based on their differing radio morphologies, powerful radio galaxies can be separated into the Fanaroff-Riley I (FR I) and II (FR II) classes. Hybrid morphology radio sources (HyMoRS) contain morphologies consistent with ...

    • LoTSS/HETDEX: Optical quasars I. Low-frequency radio properties of optically selected quasars 

      Gürkan, Gülay; Hardcastle, Martin; Best, Philip; Morabito, Leah; Prandoni, Isabella; Jarvis, Matt; Duncan, Ken; Rivera, Gabriela Calistro; Callingham, Joe; Cochrane, Rachel; Croston, Judith; Heald, George; Mingo, Beatriz; Mooney, Sean; Sabater, Jose; Röttgering, Huub; Shimwell, Timothy; Smith, Dan; Tasse, Cyril; Williams, Wendy (2018-10-10)
      The radio-loud/radio-quiet (RL/RQ) dichotomy in quasars is still an open question. Although it is thought that accretion onto supermassive black holes in the centre the host galaxies of quasars is responsible for some radio ...

    • A representative survey of the dynamics and energetics of FRII radio galaxies 

      Ineson, Judith; Croston, Judith H.; Hardcastle, Martin; Mingo, Beatriz (2017-05-01)
      We report the first large, systematic study of the dynamics and energetics of a representative sample of FRII radio galaxies with well-characterized group/cluster environments. We used X-ray inverse-Compton and radio ...
