Description

Cosmosis is a modular cosmological parameter estimation code developed by Joe Zuntz et al (see http://arxiv.org/abs/1409.3409). Cosmosis is used for the fiducial pipeline to constrain cosmological parameters with Dark Energy Survey, e.g. for constraints on models beyond wCDM (including dynamical dark energy and modified gravity) using the first year of observation in https://arxiv.org/abs/1810.02499, which I was particularly involved in. In this talk I will briefly describe Cosmosis and the way we use it for our analysis with DES.
