Abstract:
Determining an accurate position for a submillimetre (submm) galaxy
(SMG) is the crucial step that enables us to move from the basic
properties of an SMG sample source counts and 2D clustering to an
assessment of their detailed, multiwavelength properties, their
contribution to the history of cosmic star formation and their links
with present-day galaxy populations. In this paper, we identify robust
radio and/or infrared (IR) counterparts, and hence accurate positions,
for over two-thirds of the SCUBA HAlf-Degree Extragalactic Survey
(SHADES) Source Catalogue, presenting optical, 24um and radio images
of each SMG.
Description:
Wide-field radio images were obtained using the VLA.
We obtained new 1.4-GHz data for the SXDF, again using the VLA, during
2003.
R-band optical imaging for the LH and SXDF were obtained using the
Subaru 8um telescope.
The near- and mid-IR data employed here were obtained using IRAC (at
4.5 and 8um) and MIPS (at 24um).
