The mass of galaxy clusters is not a direct observable, nonetheless it commonly used to probe cosmological models. Based on the combination all main cluster observables, that is, X-ray emission, thermal Sunyaev-Zel'dovich (SZ) signal, velocity dispersion galaxies, and gravitational lensing, potential can be jointly reconstructed. We derive two ingredients required for this joint reconstruction: potentials individually reconstructed from observables their covariance matrices, which act as...
Context . Galaxy clusters provide a multitude of observational data across wavelengths, and their structure morphology are considerable interest in cosmology as well astrophysics. Aims We develop framework that allows the combination lensing non-lensing observations free-form mesh-free approach to infer projected mass distribution individual galaxy clusters. This method can be used test common assumptions on parametric models. Methods make use reconstruction code S A WL ENS 2, expand its...
