Baryonic effects for weak lensing. Part II. Combination with X-ray data and extended cosmologies
Aurel Schneider, Alexandre Refregier, Sebastian Grandis +6
An accurate modelling of baryonic feedback effects is required to exploit the full potential of future weak-lensing surveys such as Euclid or LSST. In this second paper in a series…

Baryonic effects for weak lensing. Part I. Power spectrum and covariance matrix
Aurel Schneider, Nicola Stoira, Alexandre Refregier +4
Baryonic feedback effects lead to a suppression of the weak lensing angular power spectrum on small scales. The poorly constrained shape and amplitude of this suppression is an imp…
