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