Constraints on radio source clustering towards galaxy clusters: application for cm-wavelength simulations of blind sky surveys

TL;DR

This paper constrains radio source clustering around galaxy clusters using NVSS data, aiding realistic SZE mock generation and improving predictions for cluster detection and source confusion in radio surveys.

Contribution

It provides new constraints on radio source clustering towards galaxy clusters, enhancing simulation accuracy for SZE surveys.

Findings

Radio source clustering is quantified around galaxy clusters.

Constraints improve the realism of SZE mock simulations.

Predictions for cluster detection and source confusion are refined.

Abstract

We constrain radio source clustering towards $Planck$-selected galaxy clusters using the NVSS point source catalogue. The constraint can be utilised for generating realistic Sunyaev-Zeldovich effect (SZE) mocks, and for predicting detectable clusters count and quantifying source confusion in radio surveys.
