Abstract
Spinning interstellar dust grains produce detectable rotational emission in the 10-100 GHz frequency range. We calculate the emission spectrum and show that this emission can account for the "anomalous" Galactic background component, which correlates with 100 μm thermal emission from dust. Free-free emission cannot account for the anomalous component. Implications for cosmic background studies are discussed.Keywords
