Description We propose to measure relativistic corrections to the Sunyaev-Zel.dovich effect (rSZ) in two clusters of galaxies with SPIRE-FTS, providing measurements of the intra-cluster medium (ICM) temperature with ~30 arcsec spatial resolution. For the first time, these measurements will enable: 1) unambiguous, high significance measurement of the rSZ correction, and 2) precise determination of the temperature substructure of extremely hot clusters. Both measurements are technically feasible with SPIRE-FTS and are inaccessible in any other way. The value our proposed observations for demonstrating the ability to measure the temperature of ICM substructures in massive, complex clusters is enormous, both for cosmological applications (i.e. a precise and unbiased determination of the total mass of clusters) and for astrophysical applications (untangling the complex atmosphere of clusters using SZ). These measurements will prove that measurements of the rSZ correction can enable important new studies of cluster physics and the fleeting opportunity to make them should not be missed.

Mission Description Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
