Description
Microwave and radio observations exhibit some interesting features in the Galactic plane. One of those is the Fan region which is an extended region located in the Perseus arm at a distance of 500 pc. Fan region has highly polarized emission from several MHz up to 353 GHz, which is ascribed to synchrotron but nowadays is largely unexplained. Here we present new measurements in intensity and in polarization at the microwave frequencies 10-20 GHz coming from the Multi Frequency Instrument (MFI) of the Q-U-I-JOint Tenerife Experiment (QUIJOTE). From these new maps, we present recent results on spectral energy distribution of several sources embedded in the region (the SNR 3C58 and few molecular regions), as well as the characterization of the spectral properties of the diffuse polarized emission.
