High‐frequency, high‐resolution imaging of the Sunyaev–Zel’dovich (SZ) effect is an important technique to study the complex structures of the atmospheres of merging galaxy clusters. Such observations are sensitive to the details of the electron spectrum. We show that the morphology of the SZ intensity maps in simulated galaxy clusters observed at 345, 600 and 857 GHz are significantly different because of SZ relativistic corrections. These differences can be revealed by high‐resolution imaging instruments.  We calculate relativistically corrected SZ intensity maps of a simulated, massive, merging galaxy cluster and of the massive, merging clusters 1E0657−558 (the Bullet cluster) and Abell 2219. The morphologies of the SZ intensity maps are remarkably different between 345 and 857 GHz for each merging cluster. We show that high‐resolution imaging observations of the SZ intensity maps at these frequencies, obtainable with the LABOCA and HERSCHEL‐SPIRE instruments, allow to fully exploit the astrophysical relevance of the predicted SZ morphological effect.
