QUIJOTE scientific results – IX. Radio sources in the QUIJOTE-MFI wide survey maps

We present the catalogue of Q-U-I JOint TEnerife (QUIJOTE) Wide Survey radio sources extracted from maps Multi-Frequency Instrument compiled between 2012 and 2018. The contains 786 observed in intensity polarization, is divided into two separate sub-catalogues: one containing 47 bright previously studied by \emph{Planck} collaboration an extended 739 either selected Second Catalogue Compact Sources or found through a blind search carried out with Mexican Hat 2 wavelet. A significant fraction our (38.7 per cent) are within $|b| \leq 20^\circ$ region Galactic plane. determine statistical properties for those that likely to be extragalactic. find these compatible currently available models, $\sim$1.8 Jy completeness limit at 11 GHz. provide polarimetric (38, 33, 31, 23) P detected above $99.99\%$ significance level (11, 13, 17, 19) GHz, respectively. Median polarization fractions $2.8$-$4.7$\% range 11-19 GHz frequency interval. do not distinguish extragalactic here. results presented here consistent reported literature flat- steep-spectrum sources.
