Abstract
The UKIDSS Deep eXtra-Galactic (DXS) will image an area of 35 sq.deg. at high Galactic latitudes in the J and K-band filters to a depth K = 21.0 (with 5 sq.deg. also imaged in H-band). When completed in 2012, the DXS will have used 118 nights to survey 4 of the best-studied extra-galactic fields: XMM-LSS, the Lockman Hole, SSA22 and ELAIS-N1. The principal goals of the DXS are to identify and measure the abundance of galaxy clusters at 0.8 < z < 1.5; to measure galaxy clustering in well defined samples at z > 1 (and hence measure the evolution of bias, a key test of hierarchical models); and to provide a multi-wavelength census of the luminosity density in star formation and AGN. Here, we describe some of the recent science highlights. Specifically, the discovery of a supercluster at z = 0.9 which spans >30 Mpc and has properties similar to local super-clusters (such as Hercules) and some of the first wide-field (∼3-sq.deg.) clustering measurements in EROs and DRGs.
