    Breaking baryon-cosmology degeneracy with the electron density power spectrum
    (IOP Publishing, 2022) Nicola, Andrina; Villaescusa-Navarro, Francisco; Davé, Romeel
    Uncertain feedback processes in galaxies affect the distribution of matter, currently limiting the power of weak lensing surveys. If we can identify cosmological statistics that are robust against these uncertainties, or constrain these effects by other means, then we can enhance the power of current and upcoming observations from weak lensing surveys such as DES, Euclid, the Rubin Observatory, and the Roman Space Telescope. In this work, we investigate the potential of the electron density auto-power spectrum as a robust probe of cosmology and baryonic feedback.
