| Description | We propose to measure relativistic corrections to theSunyaev-Zel.dovich effect (rSZ) in two clusters of galaxies withSPIRE-FTS, providing measurements of the intra-cluster medium (ICM)temperature with virgul30 arcsec spatial resolution. For the first time,these measurements will enable: 1) unambiguous, high significancemeasurement of the rSZ correction, and 2) precise determination of thetemperature substructure of extremely hot clusters. Both measurementsare technically feasible with SPIRE-FTS and are inaccessible in anyother way. The value our proposed observations for demonstrating theability 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 ofclusters) and for astrophysical applications (untangling the complexatmosphere of clusters using SZ). These measurements will prove thatmeasurements of the rSZ correction can enable important new studies ofcluster physics and the fleeting opportunity to make them should notbe 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. |
