Obscured AGN from the ELAIS Deep X-ray Survey
C. J. Willott, C. Simpson, O. Almaini +13
The sources discovered in deep hard X-ray surveys with 2-8 keV fluxes of 10^-14 erg cm^-2 s^-1 make up the bulk of the X-ray background at these energies. We present here detailed…
A SCUBA galaxy in the Protocluster around 53W002 at z=2.4
Ian Smail, R. J. Ivison, D. G. Gilbank +4
We analyse an 850-um SCUBA map of the environment of the z=2.39 radio galaxy 53W002, which has been shown to reside in an over-density of Ly-alpha detected galaxies. We identify fo…
GMOS Spectroscopy of SCUBA Galaxies Behind A851
M. J. Ledlow, Ian Smail, F. N. Owen +3
We have identified counterparts to two submillimeter (submm) sources, SMM J09429+4659 and SMM J09431+4700, seen through the core of the z=0.41 cluster Abell 851. We employ deep 1.4…
The Diversity of Extremely Red Objects
Ian Smail, F. N. Owen, G. E. Morrison +3
We present a multi-wavelength study of Extremely Red Objects (EROs) employing deep RIzJHK photometry of a 8.5'x8.5' region to identify 68 EROs with R-K>5.3 and K<20.5 (5-sigma). Th…
Deep radio imaging of the SCUBA 8-mJy survey fields: sub-mm source identifications and redshift distribution
Rob Ivison, Thomas Greve, Ian Smail +12
The SCUBA 8-mJy survey is the largest submm extragalactic mapping survey undertaken to date, centred on the Lockman Hole and ELAIS N2 regions. Here, we present new 1.4-GHz imaging…
The effect of lensing on the identification of bright SCUBA galaxies
S. C. Chapman, Ian Smail, R. J. Ivison +1
Spectroscopic surveys of luminous submillimetre-selected sources have uncovered optically-bright galaxies at z<1 close to the positions of several submillimetre (submm) sources. Na…
