The XMM Cluster Survey: Predicted overlap with the Planck Cluster Catalogue

TL;DR

This paper predicts which galaxy clusters detected by the XMM Cluster Survey are likely to be observed by the Planck satellite, based on cosmological models and simulation data, and discusses their properties and joint analysis prospects.

Contribution

It provides a list of 15 clusters with high Planck detection probability, incorporating detailed modeling of cluster properties and survey sensitivities, enhancing cross-survey cluster studies.

Findings

Three clusters already in the Planck ESZ catalogue.

Predicted 15 clusters with high detection probability by Planck.

Characterization of cluster properties for future joint analysis.

Abstract

We present a list of 15 clusters of galaxies, serendipitously detected by the XMM Cluster Survey (XCS), that have a high probability of detection by the Planck satellite. Three of them already appear in the Planck Early Sunyaev-Zel'dovich (ESZ) catalogue. The estimation of the Planck detection probability assumes the flat Lambda cold dark matter (LambdaCDM) cosmology most compatible with 7-year Wilkinson Microwave Anisotropy Probe (WMAP7) data. It takes into account the XCS selection function and Planck sensitivity, as well as the covariance of the cluster X-ray luminosity, temperature, and integrated comptonization parameter, as a function of cluster mass and redshift, determined by the Millennium Gas Simulations. We also characterize the properties of the galaxy clusters in the final data release of the XCS that we expect Planck will have detected by the end of its extended mission. Finally, we briefly discuss possible joint applications of the XCS and Planck data.
