Anomalous Microwave Emission Characterisation in the Taurus Molecular Cloud Complex
Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation detected in the frequency range ~10-60 GHz. AME strongly correlates with Far IR thermal dust emission almost everywhere in our Galaxy but cannot be explained by synchrotron, free-free, thermal dust or CMB emission. The nature of the carriers producing AME are still not known but theory predicts electric dipole emission from spinning dust could be at the origin of this emission. The QUIJOTE experiment operates from the Teide Observatory with the goal of characterising the polarization properties of the cosmic microwave background radiation and other Galactic and extra-galactic emission mechanisms in the frequency range 10-42GHz and at large angular scales. In this presentation I will first give a short review about AME then I will discuss the measurements in intensity and in polarisation of the emission obtained between 10 and 20 GHz with the first instrument of the QUIJOTE experiment toward the Taurus Molecular Cloud complex. I will show how such measurements help to improve and characterise the amount of AME from this region.
