Diffuse Galactic Emission from Spinning Dust Grains

Abstract

Spinning interstellar dust grains produce detectable rotational emission in\nthe 10-100 GHz frequency range. We calculate the emission spectrum, and show\nthat this emission can account for the ``anomalous'' Galactic background\ncomponent which correlates with 100um thermal emission from dust. Implications\nfor cosmic background studies are discussed.\n
