Mitigating baryon feedback bias in cosmic shear through a theoretical error covariance in the matter power spectrum
Alessandro Maraio, Alex Hall, Andy Taylor
Forthcoming cosmic shear surveys will make precise measurements of the matter density field down to very small scales, scales which are dominated by baryon feedback. The modelling…
