    • Bright Lyα emitters at z ~ 9 : Constraints on the LF from HizELS 

      Sobral, D.; Best, P.N.; Geach, J.E.; Smail, I.; Kurk, J.; Cirasuolo, M.; Casali, M.; Ivison, R.J.; Coppin, Kristen; Dalton, G.B. (2009-09-01)
      New results are presented, as part of the Hi-z Emission Line Survey (HizELS), from the largest area survey to date (1.4 deg ) for Lyα emitters (LAEs) at z ~ 9. The survey, which is primarily targeting Hα emitters at z <3, ...

      We report the detection of CO(3-2) emission from a bright, gravitationally lensed Lyman Break Galaxy, LBGJ213512.73-010143 (the 'Cosmic Eye'), at z=3.07 using the Plateau de Bure Interferometer. This is only the second ...

    • The evolution of dusty star formation in galaxy clusters to z = 1 : Spitzer infrared observations of the first red-sequence cluster survey 

      Webb, T. M. A.; O'Donnell, D.; Yee, H. K. C.; Gilbank, D.; Coppin, Kristen; Ellingson, E.; Faloon, A.; Geach, J.E.; Gladders, M.; Noble, A.; Muzzin, A.; Wilson, G.; Yan, R. (2013-10-01)
      We present the results of an infrared (IR) study of high-redshift galaxy clusters with the MIPS camera on board the Spitzer Space Telescope. We have assembled a sample of 42 clusters from the Red-Sequence Cluster Survey-1 ...

    • HiZELS - A high-redshift survey of Hα emitters - II : the nature of star-forming galaxies at z = 0.84 

      Sobral, D.; Best, P.N.; Geach, J.E.; Smail, I.; Kurk, J.; Cirasuolo, M.; Casali, M.; Ivison, R.J.; Coppin, Kristen; Dalton, G.B. (2009-09-01)
      New results from a large survey of Hα emission-line galaxies at z = 0.84 using the Wide Field Camera on the United Kingdom Infrared Telescope and a custom narrow-band filter in the J band are presented as part of the High-z ...

    • The SCUBA-2 cosmology legacy survey : Demographics of the 450-μm population

(2013-11-01)
      We investigate the multiwavelength properties of a sample of 450-μm-selected sources from the SCUBA-2 Cosmology Legacy Survey. A total of 69 sources were identified above 4σ in deep SCUBA-2 450-μm observations overlapping ...
