"Galaxy Surveys and clustering"

Abstract. Wide-area galaxy surveys map out the structure of the universe, telling us about cosmology and galaxy formation. Optical surveys from the APM to the 2dF have given evidence for a cosmological constant, baryon oscillations and luminosity bias. The Herschel-ATLAS is a new wide-area survey which will map the sky at 100 to 500 micron wavelengths. The sources detected give a sample of sub-mm galaxies which is very different to optical samples. About a half of the sub-mm sources can be associated to low redshift optical galaxies using a likelihood ratio analysis. The rest are at higher redshift. The clustering of the H-ATLAS shows a mix of local 'normal' galaxies, and a more massive high redshift galaxy population.
