Abstract: We use MUSYC observations of the Hubble Deep Field South (HDF-S) to measure galaxy clustering out to redshifts z ≈ 1 using photometric redshift information to calculate the projected correlation function Ξ(σ). Due to large redshift measurement errors, we use mock MUSYC fields extracted from a ¬§CDM simulation to determine and to correct for systematic effects. We find that the correlation length r0 of the real-space correlation function ξ(r) can be accurately recovered out to z = 1. This is also true for the mass of galaxy haloes, which we calculate using the Seljak & Warren (2004) formalism. When applied to real data, we find that the correlation length r0 shows a trend similar to that of the dark matter but is consistently higher by about a factor of 1.5, and the mass of galaxy haloes is consistent with ≈ 3M* over z = 0.3 — 1.3 and a bias of b ∼ 1.5.
