Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The accurate determination of the mass of galaxy clusters is crucial to precision astronomy. We have often to deal with either biased measurements or precise determinations of peculiar quantities. A better understanding of intrinsic shapes plays a major role. We consider how the shape of the intracluster medium (ICM) can be inferred by combining X‐ray photometry and spectroscopy with the measurement of the Sunyaev‐Zel'dovich effect (SZe). Together with gravitational lensing (GL), we can get unbiased estimates of mass and concentration and probe the hydrodynamical properties of the cluster. (© 2013 WILEY‐VCH Verlag GmbH &amp; Co.
