3. An r-band selected redshift survey: – r < 19.8mag – Six regions each ~5x12 deg – ~1000 redshift targets per sq deg (2dFGRS~120, SDSS~70) – 96% complete in redshifts – Testing ΛCDM via halo mass function, galaxy merger rates, and star formation efficiency – Total allocation 178 nights A multi-wavelength study of galaxies: – FUV,NUV,ugrizYJHK,mid-IR,far-IR,20cm,21cm,1m (AGN, stars, gas, dust) – 1kpc resolution in ugrizYJHK to z<0.1 (structural analysis) – Robust halo masses (internal/external environmental markers) Sarah Brough - Australian Astronomical Observatory
