The resummation model in FLAMINGO: precisely predicting matter power suppression from observed halo baryon fractions

Marcel P. van Daalen, Ioannis Koutalios, Jeger C. Broxterman +4

In order to derive unbiased cosmological parameters from Stage-IV surveys, we need models that can predict the matter power spectrum for at least $k\,\lesssim\,10\,h\mathrm{\,Mpc^{…
