1σ credibility region of the suppression in the matter power spectrum at z = 0 caused by baryons, inferred by the BCM model with DES Y3 data (shaded grey area). We display the ratio of the matter power spectrum affected by baryonic processes to the spectrum calculated considering only gravity. For comparison, we show the BCM models obtained in Aricò et al. (2021b), fitting several current hydrodynamical simulations referenced in the main text, according to the legend.
