ACT (ACTPol) Data Products - ACT DR4 Lensing Maps and DES-Y3 Cosmic Shear

Description

Cosmological constraints presented in Shaikh, Harrison et al. (2024) from cross-correlation of ACT DR4 lensing maps and DES-Y3 cosmic shear.

The output of the Monte Carlo chains used for estimating the posterior on cosmological and nuisance parameters. Consisting of output text files from the Cobaya mcmc sampler, including a yaml format specification for re-running the chain. Readily readable and analysable as described here with the GetDist package.

UNBLINDED_ACTPlanck_tSZfree-s3-y1_ia-all_zbins-default_dzm-default_nu
The main results chain as displayed in Figures 17, 18, B3 of the paper.

UNBLINDED_ACTPlanck_tSZfree-s3-y1_ia-highz_zbins-default_dzm-default_nu
The result using only the two highest redshift bins (3, 4) from DES, as displayed in Figure 19 of the paper.

UNBLINDED_ACTPlanck_tSZfree-s3-y1_ia-lowz_zbins-default_dzm-default_nu
The result using only the two lowest redshift bins (1, 2) from DES, as displayed in Figure 19 of the paper.

UNBLINDED_ACTPlanck_tSZfree-s3-fixed_ia-all_zbins-wide_dzm-default_nu
The result including only the highest redshift bin from DES (4) and varying only the galaxy weak lensing nuisance parameters
and , as displayed in Figure 20 of the paper.
