Description
I present the status and the recent results of the QUIJOTE (Q-U-I JOint TEnerife) experiment. QUIJOTE is a project that operates from the Teide Observatory, with the aim to characterize the emission of the galactic foregrounds at microwave wavelengths, and to study the polarization of the Cosmic Microwave Background, targeting the detection of the primordial gravitational waves, the so called "B-modes", down to a value of the tensor to scalar ratio of r = 0.05. Recently, one of the two instruments of QUIJOTE, the Multi Frequency Instrument (MFI), concluded a wide-survey campaign, during which we observed the full northern sky, at 11, 13, 17 and 19 GHz. The wide survey maps of QUIJOTE will be delivered soon to the community. Here I present the current status of the maps, and I summarize few scientific results related to them, with special emphasis on the low frequency Galactic foregrounds, such as the Synchrotron and the Anomalous Microwave Emission.
