The nature of galaxy structures on large scales is a key observational prediction for current models of galaxy formation. The SDSS and 2dF galaxy surveys have revealed a number of structures on 30-50 Mpc scales at low redshifts, and some even larger ones. To constrain galaxy number densities, luminosities and stellar populations in large structures at higher redshift, we have discovered and investigated two sheet-like structures of galaxies at z=0.8 and 1.2 spanning a 30x30 arcmin field, spanning at least 30 comoving Mpc (Lambda CDM cosmology, h=0.7) embedded in large quasar groups extending over at least 100 Mpc.
We present first results of analysis of these sheet--like structures using two
1 deg Galex fields (FUV and NUV) cross-correlated with optical data from the Sloan Digital Sky Survey (SDSS) and deep VI images from the CTIO 4m Blanco telescope. We derive a sample of about 590 Lyman Break Galaxy (LBG) candidates tracing the sheets. Using the GALEX and SDSS data, we show that the overall average spectral energy distribution of a LBG galaxy at z 1 is flat from u to z in the observed frame. This implies that there are evolved populations of stars in the LBGs.
