![]() With improved analysis techniques, the planned WALLABY (Hi) and TAIPAN (optical) redshift surveys are predicted to measure H0 to 1-3% precision. The 6dF Galaxy Survey measurement of the BAO scale gives a value of H0 = 67 ± 3.2 km s -1 Mpc-1, achieving a 1-sigma precision of 5%. yields 1.6 million objects that are subsequently used in various parts of the DES 3-year weak lensing and galaxy clustering cosmology work such as the source galaxy redshift distributions (see Myles & Alarcon et al.), shear calibration simulations (see MacCrann et al.), and simulations of the survey. Low-redshift measurements of baryon acoustic oscillations (BAO) measure the late-time evolution of the Universe and are a vital probe of dark energy. With improved analysis techniques, the planned WALLABY (Hi) and TAIPAN (optical) redshift surveys are predicted to measure H0 to 1-3% precision.ĪB - Baryon acoustic oscillations (BAO) at low redshift provide a precise and largely model-independent way to measure the Hubble constant, H0. The 6dF Galaxy Survey measurement of the BAO scale gives a value of H0 = 67 ± 3.2 km s -1 Mpc-1, achieving a 1-sigma precision of 5%. N2 - Baryon acoustic oscillations (BAO) at low redshift provide a precise and largely model-independent way to measure the Hubble constant, H0. N1 - Proceedings of IAU Symposium 289, "Advancing the Physics of Cosmic Distances", Richard de Grijs & Giuseppe Bono (eds), 2012, 4pp Tools appropriate for describing galaxy fractal structures with a single fractal dimension D in relativistic settings are developed and applied to the UltraVISTA galaxy survey. low mass galaxies per massive galaxy at high redshifts than in the local universe. T1 - Measuring H0 from the 6dF Galaxy Survey and future low-redshift surveys This thesis presents the results from a comprehensive study of 26 low-redshift galaxy clusters in order to study the radial dependence of various cluster properties. This paper seeks to test if the large-scale galaxy distribution can be characterized as a fractal system. ety of surveys to account for the number of galaxies at different redshifts. ![]()
