Herschel observations have revealed an excess (over the expectations ofnaive models of dust emission) of long-wavelength emission in manyregions of the Magellanic Clouds. We propose to determine the nature ofthis excess by measuring select regions at higher spectral resolutionusing the SPIRE FTS. Our measurements will demonstrate whetheremissivity changes, spinning dust, cold dust, or line emission are thecause of the excess emission observed at long wavelengths.

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.
