Cosmic nOn-Linearities: Impact of BaRyons on cosmological Inference with modern galaxy surveys

Cosmology is entering a new era with revolutionary surveys aimed notably at mapping dark matter and constraining the nature of dark energy. However, the observables are always related to "visible" matter (baryons) which is a biased tracer of dark matter. Baryons do not passively follow the assembly of dark matter structures, but they also feedback on the distribution of dark matter, and therefore impact significatively the estimators probing cosmology. If these effects are not precisely taken into account, they induce biases and could potentially engender apparent tensions, some of which are already observed, between the various cosmological surveys and probes. The COLIBRI project proposes…
