Diffuse Galactic Emission from Spinning Dust Grains

ApJ, 1998, 494, L19
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 mu m thermal emission from
dust.
Free-free emission cannot account for the anomalous component.
Implications
for cosmic background studies are discussed.
