The QUIJOTE experiment: status, latest results and future plans

I will review the current status and future plans of the QUIJOTE (Q-U-I JOint TEnerife) experiment, a project with the aim of characterising the polarisation of the Cosmic Microwave Background, and other galactic or extragalactic physical processes that emit in microwaves in the frequency range 10-42GHz, and at large angular scales (1 degree resolution). The project has two radio telescopes (2.25m primary aperture) and three instruments, MFI (10-20GHz), TFGI (30-40GHz) and MFI2 (10-20GHz).

In relation to MFI, which observed the sky from 2012 to 2018 at 11, 13, 17 and 19GHz, I will review the scientific results associated with the characterization of the polarized foreground emissions in the northern sky, with special emphasis on the synchrotron and AME components. These results have been presented in a series of papers between 2023 and 2024. 

I will also present status of the other two instruments, TFGI (30-40GHz) and MFI2 (10-20GHz). TFGI started operations in 2021 with 7 detectors, and will resume observations with 19 detectors this summer. Preliminary results from the period 2021-2022 will be discussed.  MFI2 has started the commissioning phase in March 2024. I will present the first light results and commissioning data. Finally, I will describe the plans for developing a 90GHz camera for QUIJOTE.
