    • The discovery of a radio galaxy of at least 5 Mpc 

      Oei, Martijn S. S. L.; Weeren, Reinout J. van; Hardcastle, Martin J.; Botteon, Andrea; Shimwell, Tim W.; Dabhade, Pratik; Gast, Aivin R. D. J. G. I. B.; Röttgering, Huub J. A.; Brüggen, Marcus; Tasse, Cyril; Williams, Wendy L.; Shulevski, Aleksandar (2022-04-01)
      Context. Giant radio galaxies (GRGs, or colloquially giants) are the Universes largest structures generated by individual galaxies. They comprise synchrotron-radiating active galactic nucleus ejecta and attain cosmological ...

    • Finding AGN remnant candidates based on radio morphology with machine learning 

      Mostert, Rafael I. J.; Morganti, Raffaella; Brienza, Marisa; Duncan, Kenneth J.; Oei, Martijn S. S. L.; Rottgering, Huub J. A.; Alegre, Lara; Hardcastle, Martin J.; Jurlin, Nika (2023-04-12)
      Context. Remnant radio galaxies represent the dying phase of radio-loud active galactic nuclei (AGN). Large samples of remnant radio galaxies are important for quantifying the radio-galaxy life cycle. The remnants of ...

    • An intergalactic medium temperature from a giant radio galaxy 

      Oei, Martijn S. S. L.; Weeren, Reinout J. van; Hardcastle, Martin J.; Vazza, Franco; Shimwell, Tim W.; Leclercq, Florent; Brüggen, Marcus; Röttgering, Huub J. A. (2022-10-16)
      The warm-hot intergalactic medium (warm-hot IGM, or WHIM) pervades the filaments of the Cosmic Web and harbours half of the Universe's baryons. The WHIM's thermodynamic properties are notoriously hard to measure. Here we ...

    • Luminous giants populate the dense Cosmic Web 

      Oei, Martijn S. S. L.; van Weeren, Reinout J.; Hardcastle, Martin J.; Gast, Aivin R. D. J. G. I. B.; Leclercq, Florent; Röttgering, Huub J. A.; Dabhade, Pratik; Shimwell, Tim W.; Botteon, Andrea (2024-06-19)
      Context. Giant radio galaxies (GRGs, giant RGs, or giants) are megaparsec-scale, jet-driven outflows from accretion disks of supermassive black holes, and represent the most extreme pathway by which galaxies can impact the ...

    • Measuring the giant radio galaxy length distribution with the LoTSS 

      Oei, Martijn S. S. L.; Weeren, Reinout J. van; Gast, Aivin R. D. J. G. I. B.; Botteon, Andrea; Hardcastle, Martin J.; Dabhade, Pratik; Shimwell, Tim W.; Röttgering, Huub J. A.; Drabent, Alexander (2023-04-19)
      Context. Many massive galaxies launch jets from the accretion disk of their central black hole, but only ∼103 instances are known in which the associated outflows form giant radio galaxies (GRGs, or giants): luminous ...
