Abstract:
Recently correlation analyses between Galactic dust emission templates and a number of CMB data sets have led to differing claims on the origin of the Galactic contamination at low frequencies. de Oliviera-Costa {\em et al.} \cite{angelica99} have presented work based on Tenerife data supporting the spinning dust hypothesis. Since the frequency coverage of the Tenerife data is ideal to discriminate spectrally between spinning dust and free-free emission, we use the latest version of the Tenerife data to study the correlation in greater detail. We find that correlation with dust exists only at low Galactic latitude, and that at present we do not have enough evidence to make a conclusive claim on the origin of the dust-correlated component.
