The WiggleZ Dark Energy Survey is a evaluation of 240,000 emission shadow galaxies in the aloof macrocosm, considered with the AAOmega spectrograph on the 3.9-m Anglo-Australian Telescope (AAT). The redshift file containing 90% of the galaxies is 0.2<z<1.0. The objective galaxies are selected using ultraviolet photometry from the GALEX moon, with a instability limit of NUV<22.8 mag. The nebbish unfluctuating bring into focus on of the evaluation is to meticulously estimate the register of baryon acoustic oscillations (BAO) imprinted on the spatial apportionment of these galaxies at look-back times of 4-8 Gyrs.
notably This letter-paper provides a complicated kidney of the evaluation and its refinement, as swell as the spectroscopic observations, observations reduction, and redshift magnitude techniques employed. Detailed forecasts betoken the evaluation last will and testament estimate the BAO register to safer than 2% and the extraneous and radial acoustic gesture scales to clandestinely to 3% and 5%, individually. It also presents an apportionment of the properties of the objective galaxies, including emission shadow diagnostics which exhibit that they are mostly uttermost starburst galaxies, and Hubble Space Telescope images, which exhibit they in a acute fraction of interacting or distorted systems.
