    • The environments of z ~ 1 active galactic nuclei at 3.6 μm 

      Falder, J.; Stevens, J. A.; Jarvis, M.J.; Hardcastle, M.J.; Lacy, M.; McLure, R.J.; Hatziminaoglou, E.; Page, M.J.; Richards, G.T. (2010)
      We present an analysis of a large sample of active galactic nuclei (AGN) environments at z∼ 1 using stacked Spitzer data at 3.6 μm. The sample contains type 1 and type 2 AGN in the form of quasars and radio galaxies, and ...

    • Herschel ATLAS: The cosmic star formation history of quasar host galaxies 

      Serjeant, S.; Bertoldi, F.; Blain, A.W.; Clements, D.; Cooray, A.; Danese, L.; Dunlop, J.S.; Dunne, L.; Eales, S.; Falder, J.; Hatziminaoglou, E.; Hughes, D.H.; Ibar, E.; Jarvis, M.J.; Lawrence, A.; Lee, M.G.; Michalowski, M.; Negrello, M.; Omont, A.; Page, M.J.; Pearson, C.; van der Werf, P.; White, G.J.; Amblard, A.; Auld, R.; Baes, M.; Bonfield, D.; Burgarella, D.; Buttiglione, S.; Cava, A.; Dariush, A.; de Zotti, G.; Dye, S.; Frayer, D.; Fritz, J.; Gonzalez-Nuevo, J.; Herranz, D.; Ivison, R.J.; Lagache, G.; Leeuw, L.; Lopez-Caniego, M.; Maddox, S.; Pascale, E.; Pohlen, M.; Rigby, E.; Rodighiero, G.; Samui, S.; Sibthorpe, B.; Smith, Daniel; Temi, P.; Thompson, M.A.; Valtchanov, I.; Verma, A. (2010)
      We present a derivation of the star formation rate per comoving volume of quasar host galaxies, derived from stacking analyses of far-infrared to mm-wave photometry of quasars with redshifts 0 < z < 6 and absolute I-band ...

    • 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 ...
