Constraining the anomalous microwave emission mechanism in the S140 star-forming region with spectroscopic observations between 4 and 8 GHz at the Green Bank Telescope

Abstract:

Anomalous microwave emission (AME) is a category of Galactic signals that cannot be explained by synchrotron, thermal dust, or optically thin free–free radiation. Spinning dust is one variety of AME that could be partially polarized and is therefore relevant for cosmic microwave background polarization studies. The Planck satellite mission identified candidate AME regions in approximately 1° patches that were found to have spectra generally consistent with spinning dust grain models. The spec...
