    • The disc-dominated host galaxy of FR-I radio source B2 0722+30 

      Emonts, B.H.C.; Tadhunter, C.N.; Morganti, R.; Oosterloo, T.A.; Holt, J.; Brogt, E.; van Moorsel, G. (University of Canterbury. University Centre for Teaching and Learning, 2009)
      We present new observational results that conclude that the nearby radio galaxy B2 0722+30 is one of the very few known disc galaxies in the low–redshift Universe that host a classical double–lobed radio source. In this ...
    • From major merger to radio galaxy: Low surface-brightness stellar counterpart to the giant HI ring around B2 0648+27 (Research Note) 

      Emonts, B.H.C.; Morganti, R.; van Gorkom, J.H.; Oosterloo, T.A.; Brogt, E.; Tadhunter, C.N. (University of Canterbury. University Centre for Teaching and LearningUniversity of Canterbury. AVC Research Office, 2008)
      We present the detection of a low surface-brightness stellar counterpart to an enormous (190 kpc) ring of neutral hydrogen (HI) gas that surrounds the nearby radio galaxy B2 0648+27. This system is currently in an ...
    • Large-scale HI in nearby radio galaxies (II): The nature of classical low-power radio sources 

      Emonts, B.H.C.; Morganti, R.; Struve, C.; Oosterloo, T.A.; van Moorsel, G.; Tadhunter, C.N.; van der Hulst, J.M.; Brogt, E.; Holt, J.; Mirabal, N. (University of Canterbury. AVC Research Office, 2010)
      n important aspect of solving the long-standing question as to what triggers various types of active galactic nuclei (AGN) involves a thorough understanding of the overall properties and formation history of their host ...

      On February 17, 2016, the IceCube real-time neutrino search identified, for the first time, three muon neutrino candidates arriving within 100 s of one another, consistent with coming from the same point in the sky. Such ...
    • Short time-scale optical variability properties of the largest AGN sample observed with Kepler/K2 

      Aranzana E; Körding E; Uttley P; Scaringi S; Bloemen S (2018)
      © 2017 The Authors. We present the first short time-scale (~hours to days) optical variability study of a large sample of active galactic nuclei (AGNs) observed with the Kepler/K2 mission. The sample contains 252 AGN ...
