Descripción
We have used the seven-year Wilkinson Microwave Anisotropy Probe (WMAP)
data in order to update the measurements of the intensity signal in the
G159.6-18.5 region within the Perseus molecular complex and to set
constraints on the polarization level of the anomalous microwave
emission in the frequency range where this emission is dominant. At 23,
33, and 41 GHz, we obtain upper limits on the fractional linear
polarization of 1.0%, 1.8%, and 2.7%, respectively (with a 95%
confidence level). These measurements rule out a significant number of
models based on magnetic dipole emission of grains that consist of a
simple domain as responsible for the anomalous emission. When combining
our results with the measurement obtained with the COSMOSOMAS experiment
at 11 GHz, we find consistency with the predictions of the electric
dipole and resonance relaxation theory at this frequency range.
