Description |
Herschel observations have revealed an excess (over the expectations of naive models of dust emission) of long-wavelength emission in many regions of the Magellanic Clouds. We propose to determine the nature of this excess by measuring select regions at higher spectral resolution using the SPIRE FTS. Our measurements will demonstrate whether emissivity changes, spinning dust, cold dust, or line emission are the cause of the excess emission observed at long wavelengths. |
