Class_sz (Bolliet et al) is a code built on Class (Lesgourgues et al) which enables to compute nearly all cosmological power spectra relevant to upcoming CMB and LSS surveys (tsz and ksz, lensing, galaxies, CIB), including cross-correlations and cluster counts for SZ surveys. It is being used in the developpement of pipelines within the Atacama Cosmology Telescope and Simons Observatory. I propose to present the overall architecture of the codes and show different computation, as well as presenting how to interface it with cosmopower (Spurio-Mancini et al) for machine learning emulation. This would be a talk for the Tools and Methodology Working Group.
