Joint analysis of shear-tSZ cross-correlations and cosmic shear with KiDS-1000, Planck, and ACT

This repository contains the scripts, utilities, data vectors, and covariances used in the paper Joint constraints on cosmology and the impact of baryon feedback: combining KiDS-1000 lensing with the thermal Sunyaev-Zeldovich effect from Planck and ACT.

The main dependencies are

• NaMaster, for the estimation of the pseudo-Cls and Gaussian covariances,
• pyhmcode, for the non-linear power spectra models and halo profiles,
• CCL, for the non-Gaussian covariance contributions,
• kcap, for the inference pipeline.

Repository structure

• data/: Contains catalogue statistics and data products with multiple applications (e.g., speficiation of the ell-binning).
• notebooks/: Collection of Jupyter notebooks used in data reduction and exploration.
• results/: Data vectors and covariances used in the analysis.
• paper/: Scripts to create the plots used in the paper.
• scripts/: Collection of scripts used in the data reduction. The measurement "pipeline" is described in scripts/README.md.
• tools/: Collection of tools used in the analysis. The distinction between scripts and tools is somewhat arbitrary.
