Abstract
- We present observations between 14.2 and 17.9 GHz of 16 Galactic H II regions made withthe Arcminute Microkelvin Imager. In conjunction with data from the literature at lower radiofrequencies we investigate the possibility of a spinning dust component in the spectra of theseobjects. We conclude that there is no signi?cant evidence for spinning dust towards thesesources and measure an average spectral index of a = 0.15 ± 0.07 (where S ? ?-a) between1.4 and 17.9 GHz for the sample.
