      Mingo, B.; Croston, J. H.; Best, P. N.; Duncan, K. J.; Hardcastle, M. J.; Kondapally, R.; Prandoni, I.; Sabater, J.; Shimwell, T. W.; Williams, W. L.; Baldi, R. D.; Bonato, M.; Bondi, M.; Dabhade, P.; Gürkan, G.; Ineson, J.; Magliocchetti, M.; Miley, G.; Pierce, J. C. S.; Röttgering, H. J. A. (2022-02-16)
      Radio-loud active galaxies have two accretion modes [radiatively inefficient (RI) and radiatively efficient (RE)], with distinct optical and infrared signatures, and two jet dynamical behaviours, which in arcsec- to ...

    • CO observations of high-z radio galaxies MRC 2104-242 and MRC 0943-242 : Spectral-line performance of the Compact Array Broadband Backend 

      Emonts, B.H.C.; Norris, R.P.; Feain, I.; Miley, G.; Sadler, E.M.; Villar-Martin, M.; Mao, M.Y.; Oosterloo, T.A.; Ekers, R.D.; Stevens, J.B.; Wieringa, M. H.; Coppin, Kristen; Tadhunter, C.N. (2011-07-01)
      We present the first 7-mm observations of two high-redshift, Lyα-bright radio galaxies (MRC 2104-242 and MRC 0943-242) performed with the 2 × 2GHz instantaneous bandwidth of the Compact Array Broadband Backend (CABB) at ...

    • The Herschel view of the environment of the radio galaxy 4C+41.17 at z = 3.8 

      Wylezalek, D.; Vernet, J.; De Breuck, C.; Stern, D.; Galametz, A.; Seymour, N.; Jarvis, M.J.; Barthel, P.; Drouart, G.; Greve, T.R.; Haas, M.; Hatch, N.; Ivison, R.; Lehnert, M.; Meisenheimer, K.; Miley, G.; Nesvadba, N.; Rottgering, H.J.A.; Stevens, J.A. (2013-02-01)
      We present Herschel observations at 70, 160, 250, 350 and 500 μm of the environment of the radio galaxy 4C+41.17 at z = 3.792. About 65 per cent of the extracted sources are securely identified with mid-infrared sources ...

      Context. The Low Frequency Array (LOFAR) is the only existing radio interferometer able to observe at ultra-low frequencies (<100 MHz) with high resolution (<15") and high sensitivity (<1 mJy beam-1). To exploit these ...

    • The LOFAR view of FR0 radio galaxies 

      Capetti, A.; Brienza, M.; Baldi, R. D.; Giovannini, G.; Morganti, R.; Hardcastle, M. J.; Rottgering, H. J. A.; Brunetti, G. F.; Best, P. N.; Miley, G. (2020-10-09)
      We explore the low-frequency radio properties of the sources in the Fanaroff-Riley class 0 catalog (FR0CAT) as seen by the LOw Frequency ARray (LOFAR) observations at 150 MHz. This sample includes 104 compact radio active ...
