Description

Albert Chuang (Stanford University)

On-going and future galaxy surveys, e.g. DESI, Euclid, WFIRST, etc., are going to reach sub-percentage accuracy on the cosmological measurements, e.g., Baryon Acoustic Oscillation, growth rate of large-scale structure, etc. A robust methodology is required while reaching such precision. Any minor systematic error from observations, data analysis, or theoretical models might not be negligible for future surveys. I would like to give updates on the current methods, point out the potential systematics, and discuss the solutions.
