    • Deep spitzer observations of infrared-faint radio sources : high-redshift radio-loud active galactic nuclei? 

      Norris, R.P.; Afonso, J.; Cava, A.; Farrah, D.; Huynh, M.T.; Ivison, R.J.; Jarvis, M.J.; Lacy, M.; Mao, M.; Maraston, C.; Mauduit, J.C.; Middelberg, E.; Oliver, S.; Seymour, N.; Surace, J. (2011)
      Infrared-faint radio sources (IFRSs) are a rare class of objects which are relatively bright at radio wavelengths but very faint at infrared and optical wavelengths. Here we present sensitive near-infrared observations of ...
    • An Extreme Starburst in the Core of a Rich Galaxy Cluster at z = 1.7 

      Webb, T.; Noble, A.; DeGroot, A.; Wilson, G.; Muzzin, A.; Bonaventura, N.; Cooper, M.; Delahaye, A.; Foltz, R.; Lidman, C.; Surace, J.; Yee, H.~K.~C.; Chapman, S.; Dunne, L.; Geach, J.; Hayden, B.; Hildebrandt, H.; Huang, J.; Pope, A.; Smith, M.~W.~L.; Perlmutter, S.; Tudorica, A. (2015-08-21)
      We have discovered an optically rich galaxy cluster at z = 1.7089 with star formation occurring in close proximity to the central galaxy. The system, SpARCS104922.6+564032.5, was detected within the Spitzer Adaptation of ...
    • Red but not dead: unveiling the star-forming far-infrared spectral energy distribution of SpARCS brightest cluster galaxies at 0 $ z $ 1.8 

      Bonaventura, N.~R.; Webb, T.~M.~A.; Muzzin, A.; Noble, A.; Lidman, C.; Wilson, G.; Yee, H.~K.~C.; Geach, J.; Hezaveh, Y.; Shupe, D.; Surace, J. (2017-08-01)
      We present the results of a Spitzer/Herschel infrared photometric analysis of the largest (716) and the highest-redshift (z = 1.8) sample of brightest cluster galaxies (BCGs), those from the Spitzer Adaptation of the ...
    • The SCUBA Half-Degree Extragalactic Survey (SHADES) - VIII : The Nature of Faint Submillimetre Galaxies in SHADES, SWIRE and SXDF Surveys 

      Clements, D. L.; Vaccari, M.; Babbedge, T.; Oliver, S.; Rowan-Robinson, M.; Davoodi, P.; Ivison, R.; Farrah, D.; Dunlop, J.; Shupe, D.; Waddington, I.; Simpson, C.; Furusawa, H.; Serjeant, S.; Afonso-Luis, A.; Alexander, D.M.; Aretxaga, I.; Blain, A.; Borys, C.; Chapman, S.; Coppin, Kristen; Dunne, L.; Dye, S.; Eales, S. A.; Evans, T.; Fang, F.; Frayer, D.; Fox, M.; Gear, W.K.; Greve, T.R.; Halpern, M.; Hughes, D.H.; Jenness, T.; Lonsdale, C.J.; Mortier, Angela M. J.; Page, M.J.; Pope, A.; Priddey, Robert Stephen; Rawlings, S.; Savage, R.S.; Scott, D.; Scott, S.E.; Sekiguchi, K.; Smail, I.; Smith, H.E.; Stevens, Jason; Surace, J.; Takagi, T.; van Kampen, E. (2008)
      We present the optical-to-submm spectral energy distributions for 33 radio & mid-IR identified submillimetre galaxies discovered via the SHADES 850μm SCUBA imaging in the Subaru-XMM Deep Field (SXDF). Optical data for the ...
    • The spitzer extragalactic representative volume survey (SERVS) : the environments of high-z SDSS quasi-stellar-objects 

      Falder, J.; Stevens, J. A.; Jarvis, M.J.; Bonfield, David; Lacy, M.; Farrah, D.; Oliver, S.; Surace, J.; Mauduit, J.C.; Vaccari, M.; Marchetti, L.; Gonzalez-Solares, E.; Afonso, J.; Cava, A.; Seymour, N. (2011)
      This paper presents a study of the environments of SDSS quasi-stellar objects (QSOs) in the Spitzer Extragalactic Representative Volume Survey (SERVS). We concentrate on the high-redshift QSOs as these have not been studied ...
