Abstract: A byproduct of experiments designed to map the CMB is the recent detection of a new component of foreground Galactic emission. The anomalous foreground at 10—30 GHz, unexplained by traditional emission mechanisms, correlates with 100 μm dust emission, and is thus presumably due to dust. Is the anomalous foreground ubiquitous in the Galaxy? We present evidence obtained with the CBI experiment supporting the existence of the new component in specific objects, in the form of a 31 GHz excess over free-free emission in HII regions, planetary nebulae, and a surprisingly radio-bright dark cloud.
