<ul><li>Baryonic physics significantly influences the distribution of matter in the Universe on cosmological scales, making it a crucial factor in cosmological surveys.</li><li>Researchers have developed symbolic parametrizations to model the impact of baryonic physics on the matter power spectrum for various models, considering parameters such as wavenumber, redshift, cosmology, and baryonic feedback control.</li><li>The study utilizes symbolic regression to create analytic approximations for the ratio of the matter power spectrum with baryons to that without, considering different sub-grid prescriptions of baryonic physics from hydrodynamical simulations.</li><li>Their analytic expressions allow for a direct understanding of how changing cosmological and feedback parameters affects the models, enabling distinctions between different baryonic physics implementations when analyzing real data.</li></ul>
