Abstract
We present the first cluster catalogue extracted from the UKIRT Infrared
Deep Sky Survey (UKIDSS) Early Data Release. The catalogue is created
using UKIDSS Ultra Deep Survey infrared J and K data combined with 3.6-
and 4.5-μm Spitzer bands and optical BVRi'z' imaging from the Subaru
Telescope over 0.5 deg2 in the Subaru XMM-Newton Deep Field.
We have created a new cluster detection algorithm, based on the
friends-of-friends and Voronoi tessellation methods, which utilizes
probability distribution functions derived from a photometric redshift
analysis. We employ mock catalogues to understand the selection effects
and contamination associated with the algorithm. The cluster catalogue
contains 13 clusters at redshifts 0.61 1014Msolar) clusters is
precisely in line with theoretical predictions presented by Kneissl et
al.
