Microwave observations of spinning dust emission in NGC 6946

We report new cm-wave measurements at five frequencies between 15 and 18 GHz of thecontinuum emission from the reportedly anomalous ‘region 4’ of the nearby galaxyNGC6946.We find that the emission in this frequency range is significantly in excess of that measuredat 8.5 GHz, but has a spectrum from...
