AI Article Synopsis
- The discovery of dust-correlated diffuse microwave emission has led to two competing theories: it could be either free-free emission or spinning dust grains.
- Recent results from the Tenerife experiment detected this emission at 10 and 15 GHz, showing a spectrum turnover that favors the spinning dust hypothesis.
- Additionally, a notable detection of synchrotron radiation at 10 GHz helps in adjusting for foreground contamination in cosmic microwave background studies, particularly at high galactic latitudes.
Article Abstract
The recent discovery of dust-correlated diffuse microwave emission has prompted two rival explanations: free-free emission and spinning dust grains. We present new detections of this component at 10 and 15 GHz by the switched-beam Tenerife experiment. The data show a turnover in the spectrum and thereby support the spinning dust hypothesis. We also present a significant detection of synchrotron radiation at 10 GHz, which is useful for normalizing foreground contamination of cosmic microwave background experiments at high galactic latitudes.
