Measured angular power spectra of KiDS-1000 cosmic shear (bottom left) and the angular cross-power spectra between KiDS-1000 shear and the tSZ effect (top right). Shown here is the cross-correlation using the MILCAPlanck Compton-y map. The grey bands indicate the 68th and 95th percentile of the posterior predictive distribution (PPD) of the joint-analysis posterior. Coloured lines are samples of the translated posterior distribution (TPD), with the colour corresponding to the baryon feedback strength. Since the TPD is derived from the full joint-posterior, the baryon feedback strength only accounts for part of the variance of the shown TPD samples.
