Making CLOE shine: a code to unveil the mysteries of the Dark Universe

In the context of the improvement in cosmological data expected for the current decade, the European Space Agency mission Euclid, whose launch is expected for early 2023, will map the Universe’s structure by studying two main complementary observational probes: the Weak Lensing effect and Galaxy Clustering. These two probes are able to trace the expansion rate of the universe and the growth of cosmic structures. Hence, the goal of the Euclid mission is to bring some “light” about the origin and nature of Dark Energy and Dark Matter by studying their effects on these two probes.

This workshop is dedicated to the development of the necessary tools to exploit such data, in particular to the code “Cosmology Likelihood for Observables in Euclid” (CLOE), the official likelihood code of the Euclid Consortium. The focus points of the workshop will be:

1. IST:L KeyProjects: encode the modeling of cosmological observables and the statistical analysis of data done in CLOE in scientific papers, necessary to disseminate the research done within the Euclid Consortium to the cosmological community;
2. Improve CLOE performance and structure, in order for it to be ready for use once the data of the Euclid Satellite will be available.

Concretely, the workshop will feature general discussions between the participants aimed at identifying the optimal way to move forward in these two tasks, as well as practical work in small groups where both the coding development and the writing of the papers will be carried out.
