dc.description.abstractWe combine a semi-analytical model of galaxy formation with a very large simulation which follows the growth of a large-scale structure in a Lambda cold dark matter (Lambda CDM) universe to predict the clustering of Ly alpha emitters. We find that the clustering strength of Ly alpha emitters has only a weak dependence on Ly alpha luminosity but a strong dependence on redshift. With increasing redshift, Ly alpha emitters trace progressively rarer, higher density regions of the universe. Due to the large volume of the simulation, over 100 times bigger than any previously used for this application, we can construct mock catalogues of Ly alpha emitters and study the sample variance of current and forthcoming surveys. We find that the number and clustering of Ly alpha emitters in our mock catalogues are in agreement with measurements from current surveys, but there is a considerable scatter in these quantities. We argue that a proposed survey of emitters at z = 8.8 should be extended significantly in solid angle to allow a robust measurement of Ly alpha emitter clustering.
