Data repository for Shaikh, Harrison et al (2023) on ACT-DR4 CMB lensing x DES-Y3 cosmic shear.

Contents:

data/

UNBLINDED_ACTPlanck_tSZfree_ACTDR4-kappa_DESY3-gamma_data_simCov.fits
The data vector used in the work. Consisting of a sacc format fits file with power spectrum band powers, band power window functions, binned covariance matrix and galaxy redshift distributions for the four DES tomographic bins. A summary plot is shown in Figure 16 of the paper.

chains/

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 $m$ and $\Delta z$, as displayed in Figure 20 of the paper.

Citation

These data and chains were generated as part of the work:

Cosmology from Cross-Correlation of ACT-DR4 CMB Lensing and DES-Y3 Cosmic Shear
S. Shaikh, I. Harrison, A. van Engelen, G. Marques et al. arXiv: 2309.04412. To be submitted to Monthly Notices of the Royal Astronomical Society.

The data vector in this analysis was formed by combining the ACT-DR4 lensing map:

The Atacama Cosmology Telescope: A CMB lensing mass map over 2100 square degrees of sky and its cross-correlation with BOSS-CMASS galaxies
O. Darwish et al. Monthly Notices of the Royal Astronomical Society 500 (2021) 2, 2250-2263. arXiv: 2004.01139, DOI: 10.1093/mnras/staa3438

with the DES-Y3 shear catalogue:

Dark energy survey year 3 results: weak lensing shape catalogue
M. Gatti & E. Sheldon et al. Monthly Notices of the Royal Astronomical Society 504 (2021) 3, 4312-4336. arXiv: 2011.03408. DOI: 10.1093/mnras/stab918
