Constraints on the amplitude of the tSZ and kSZ power spectra at ℓ = 3000 and 143 GHz, using different data sets and methods to account for the tSZ signal. In grey and black are shown results obtained when using templates Reichardt et al. (2021), with and without varying cosmology, respectively. Other colours refer to results using the halo model to derive the tSZ power and freeing cosmology. In blue, only SPT data is considered. In green and red, Planck21-tSZ data is added, with Gaussian and uniform prior on the bias parameter, respectively. and are given in μK².
