Nuisance parameters for large galaxy surveys

By Sandrine Codis

Abstract

These notes are based on a lecture given at the 2016 Euclid Summer School in Narbonne. I will first give a quick overview of the concept of nuisance parameters in the context of large galaxy surveys. The second part will examine the case study of intrinsic alignments, a potential important contamination of weak lensing observables.Comment: 17 pages, introductory lecture given at the 2016 Euclid Summer School, text may overlap with hal.archives-ouvertes.fr/tel-01264538v
