We propose a panoramic photometric redshift survey of two overdense regions at z=0.82 and z=1.06 to map the variation in galaxy properties with local environment at this early epoch. These regions are two of the highest concentrations of AGN in the 2dF QSO redshift survey: with 9 and 6 UV-selected QSOs in 30-Mpc diameter fields spanning very narrow redshift ranges, (Delta)z< 0.02. These structures appear to be high-z analogues of the filaments and superclusters in the local Universe, but seen at a time when the Universe was only 40% of its present age. We will obtain VRiz imaging to estimate photometric redshifts for 40,000 galaxies in each field and so isolate the population clustered around the QSO groups at z~1. Our analysis will provide not only a two- dimensional map of the large scale structure in which the QSOs reside, but will also provide crude information on their star formation properties. By tracking the evolution of galaxy properties across a wide range in redshift and environment, we aim to disentangle the competing effects of cosmic epoch and local environment in defining the characteristics of galaxies at z=0.
