Radio Observations of the Subaru/XMM-Newton Deep Survey Field

Abstract

The Subaru/XMM-Newton Deep Survey[1] (SXDS) comprises deep optical and X-ray observations of an area of sky larger than a square degree. With a transverse size of 100 Mpc at z = 1.5, the SXDS can detect and measure large-scale structure which will strongly affect the global results from smaller surveys. This region of sky is also home to a 0.8-deg² ultra-deep near-infrared imaging survey [2], a 0.25-deg² submillimetre survey [3], and also lies within the XMM-LSS region which will be observed by SIRTF as part of the SWIRE Legacy Program [4], and by GALEX as part of its Deep Imaging Survey and Medium–Deep Spectroscopic Survey. Extragalactic radio sources are able to probe large-scale structure and inform on the accretion and star formation histories of the Universe, and we have therefore undertaken deep radio observations to complete an unparalleled multi-wavelength dataset. This paper introduces the radio data in this field.
