Abstract: Baryon Acoustic Oscillation (BAO) are one of the key cosmological probes available and much progress has been made to understand the dynamics of the Universe through measurements at different redshifts. Over the past decade the methodology of density field reconstruction has been designed and applied to many surveys, removing the non-linear bulk flow displacements from galaxies and offering tighter distance constraints. In this talk I will give an overview of my work applying FFT-based reconstruction to the 6-degree Field Galaxy Survey. Following from the initial detection of BAO in Beutler et al. (2011), this project aims to remove non-linearities in the galaxy field and hence improve constraints on the most local BAO measurement. Secondary to this we offer a more robust covariance matrix to the previous analysis, through the generation of COLA mock catalogues which have been populated through a halo occupation distribution prescription. Following this I will also talk briefly about my involvement with the DESI bright galaxy survey working group and the planned application of reconstruction to the MXXL mocks which have been produced to mimic the survey. Finally I will mention my future planned work to investigate systematics caused by the assumption of fiducial cosmology to the BAO peak position post-reconstruction.”
