AMICO galaxy clusters in KiDS-DR3
Listed in IVOA Registry (Virtual Observatory)
We analysed the clustering of a photometric sample of galaxy clusters selected from the Third Data Release of the Kilo-Degree Survey, focusing on the redshift-space two-point correlation function (2PCF).
Description
We compared our measurements to theoretical predictions of the standard {Lambda} cold dark matter ({Lambda}CDM) cosmological model. We measured the 2PCF of the sample in the cluster-centric radial range r {in} [5,80]h^-1^Mpc, considering 4934 galaxy clusters with richness {lambda}^*^>=15 in the redshift range z {in} [0.1,0.6].
A Markov chain Monte Carlo analysis has been performed to constrain the cosmological parameters {Omega}_m_, {sigma}_8_, and S_8_~{sigma}_8_({Omega}_m_/0.3)^0.5^, assuming Gaussian priors on the mass-richness relation given by the posteriors obtained from a joint analysis of cluster counts and weak lensing. In addition, we constrained the normalisation of the mass-richness relation, {alpha}, with fixed cosmological parameters.

We obtained {Omega}_m_=0.28^+0.05^_-0.04_, {sigma}_8_=0.82^+0.14^_-0.12_, and S_8_=0.80^+0.08^_-0.08_. The constraint on S_8_ is consistent within 1{sigma} with the results from WMAP and Planck. Furthermore, by fixing the cosmological parameters to those provided by Planck, we obtained {alpha}=0.12^+0.06^_-0.06_, which is fully consistent with the result obtained from the joint analysis of cluster counts and weak lensing performed for this sample.
