| 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. |
