Info & Download


The tSZ and kSZ power spectra are computed with a Random Forest algorithm trained with the halo model approach.

See Douspis, Salvati, Gorce, Aghanim 2022 (Astronomy and Astrophysics) and Gorce, Douspis, Salvati 2022 (Astronomy and Astrophysics) for more information.

The code for computing the spectra is available for download on this gitlab site
