Can a galaxy redshift survey measure dark energy clustering?


A wide-field galaxy redshift survey allows one to probe galaxy clustering at largest spatial scales, which carries invaluable information on horizon-scale physics complementarily to the cosmic microwave background (CMB). Assuming the planned survey consisting of z ∼ 1 and z ∼ 3 surveys with areas of 2000 and 300 deg, respectively, we study the prospects for… (More)
