AMICO galaxy clusters in KiDS-1000: cosmological constraints and mass calibration from counts and weak lensing

Abstract

We present the joint modelling of weak-lensing and count measurements of the galaxy clusters detected with the AMICO code, in the fourth data release of the Kilo Degree Survey (KiDS-1000). The analysed sample comprises about 8000 clusters, covering an effective area of 839 deg${}^2$ and extending up to a redshift of $z=0.8$. Stacked cluster weak-lensing and count measurements have been derived in bins of redshift and intrinsic richness, ${\lambda }^{\ast }$. Based on self-organising maps, we reconstructed the true redshift distributions of the background galaxy samples. We accounted for the systematic uncertainties arising from impurities in the background and cluster samples, biases in the cluster $z$ and ${\lambda }^{\ast }$, projection effects, halo orientation and miscentring, truncation of cluster halo mass distributions, matter correlated with cluster haloes, multiplicative shear bias, baryonic matter, geometric distortions in the lensing profiles, uncertainties in the theoretical halo mass function, and super-sample covariance. We also employed a blinding strategy based on perturbing the cluster sample completeness. The improved statistics and photometry compared to the previous KiDS data release, KiDS-DR3, have led to a halving of the uncertainties on ${\Omega }_{\mathrm{m}}$ and ${\sigma }_8$, as we obtained ${\Omega }_{\mathrm{m}}=0.22\pm 0.02$ and ${\sigma }_8=0.86\pm 0.03$. The constraint on $S_8\equiv {\sigma }_8({\Omega }_{\mathrm{m}}/0.3{)}^{0.5}$, $S_8=0.74\pm 0.03$, is in excellent agreement with recent cluster count and KiDS-1000 cosmic shear analyses, while it shows a $2.8\sigma$ tension with Planck cosmic microwave background results. The constraints on the $\log {\lambda }^{\ast }-\log M_{200}$ relation imply a mass precision of 8%, on average. In addition, the result on the intrinsic scatter of the $\log {\lambda }^{\ast }-\log M_{200}$ relation, ${\sigma }_{\mathrm{intr}}=0.05\pm 0.02$, confirms that ${\lambda }^{\ast }$ is an excellent mass proxy.
