    • Galaxy Clusters around Radio-loud Active Galactic Nuclei at 1.3 lt z lt 3.2 as seen by Spitzer 

      Wylezalek, D.; Galametz, A.; Stern, D.; Vernet, J.; De Breuck, C.; Seymour, N.; Brodwin, M.; Eisenhardt, P.R.M.; Gonzalez, A.H.; Hatch, N.; Jarvis, M.J.; Rettura, A.; Stanford, S. A.; Stevens, J.A. (2013-05-01)
      We report the first results from the Clusters Around Radio-Loud AGN program, a Cycle 7 and 8 Spitzer Space Telescope snapshot program to investigate the environments of a large sample of obscured and unobscured luminous ...

    • 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 ...

    • Rapid Coeval Black Hole and Host Galaxy Growth in MRCnbsp1138-262 : The Hungry Spider 

      Seymour, N.; Altieri, B.; De Breuck, C.; Barthel, P.; Coia, D.; Conversi, L.; Dannerbauer, H.; Dey, A.; Dickinson, M.; Drouart, G.; Galametz, A.; Greve, T.R.; Haas, M.; Hatch, N.; Ibar, E.; Ivison, R.; Jarvis, M.J.; Kovács, A.; Kurk, J.; Lehnert, M.; Miley, G.; Nesvadba, N.; Rawlings, J.I.; Rettura, A.; Röttgering, H.; Rocca-Volmerange, B.; Sánchez-Portal, M.; Santos, J. S.; Stern, D.; Stevens, J.; Valtchanov, I.; Vernet, J.; Wylezalek, D. (2012-08-01)
      We present a detailed study of the infrared spectral energy distribution of the high-redshift radio galaxy MRC1138-26 at z = 2.156, also known as the Spiderweb Galaxy. By combining photometry from Spitzer, Herschel and ...

    • Why z > 1 radio-loud galaxies are commonly located in protoclusters 

      Hatch, N. A.; Wylezalek, D.; Kurk, J. D.; Stern, D.; Breuck, C. De; Jarvis, M.J.; Galametz, A.; Gonzalez, A. H.; Hartley, W. G.; Mortlock, A.; Seymour, N.; Stevens, J. A. (2014-11-21)
      Distant powerful radio-loud active galactic nuclei (RLAGN) tend to reside in dense environments and are commonly found in proto-clusters at z > 1.3. We examine whether this occurs because RLAGN are hosted by massive galaxies, ...
