In this talk, I present the recent data analysis of the COSMOSOMAS experiment. The COSMOSOMAS experiment is placed at the Observatorio del Teide (Tenerife, 2400 m). It observes the sky with 5 channels between 10 and 17 GHz, covering a daily sky region of ca. 7000 squared degrees, with an angular resolution of 1 degree. Its aim is the study of CMB and Galactic foregrounds. The lower range frequency of the COSMOSOMAS experiment compared to the WMAP mission or the forthcoming Planck Surveyor mission, provides a natural complement for lower frequency behaviour of Galactic and extra Galactic foregrounds. In particular, the COSMOSOMAS experiment has given proofs for the existence of a new foreground emission: anomalous dust emission. In this poster, we also discuss whether the COSMOSOMAS data are consistent with a spinning dust model and whether this emission is also present at high Galactic latitudes. Finally, we present first measurements of the polarization of this anomalous dust emission in the Perseus molecular cloud which amounts to Π = 3.4 ± 2% at 10.9 GHz.
