摘要：
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 mu m thermal emission from dust. Free-free emission cannot account for the anomalous component. Implications for cosmic background studies are discussed.
