IFCA Group

THE IFCA GROUP, led by E. Martínez-González, has experience in different aspects of CMB data analysis, including mapmaking, astrophysical diffuse source separation (foreground cleaning), point source detection and statistical analysis, study of non-Gaussianity and deviations from statistical isotropy of the CMB, cosmological parameter estimation, etc. Besides, the IFCA is one of the most important high performance computing centers in Spain; its resources, in combination with the experience of the researchers belonging to this Institute, makes it an outstanding center for the processing and analysis of QUIJOTE data, as well as the joint analysis of Planck and QUIJOTE. The IFCA will contribute to the development and simulation of the 42 GHz instrument in collaboration with the DICOM group. Regarding the development and testing of the interferometer pathfinder at 30 GHz, the IFCA will contribute to the design and development of different concepts of the an analogical correlator, in collaboration with the Manchester group.

IAC Group

THE IAC GROUP, led by R. Rebolo and J.A. Rubiño-Martín, has participated in many CMB experiments during the last decade, including Planck, VSA and the Tenerife experiment, and has a lot of experience in all the different stages of the design, installation, maintenance and scientific exploitation (e.g. determination of cosmological parameters and characterisation of the Galactic emissions) of experiments. Besides, the Teide Observatory in Tenerife is the physical location of QUIJOTE, being Rafael Rebolo its PI and the IAC has led the design and construction of the telescope, enclosure and first multi-frequency instrument. It is also main responsible for integration, operation, data reduction and analysis for the phase I and will be in charge of the opto-mechanics, electronics and control software of the 42GHz instrument, including integration and verification. Regarding the interferometer pathfinder, the IAC will provide the rotational platform to place it as well as study the feasibility of a digital correlator based on FPGAs in collaboration with Cambridge. The IAC has a wide experience in the development, commissioning and operation of interferometers in the microwave range (VSA, JBO-IAC 33 GHz), and also in developing and simulating FPGAs based systems.

DICOM Group

THE DICOM GROUP, whose responsible is E. Artal, is a leading centre in the design and development of MMIC and low noise amplifier technologies. It has a lot of experience with European foundries like OMMIC (Limeil-Brévannes, France) and IAF-Fraunhofer (Freiburg, Germany) and maintains close collaborations with leading European centres like the Fraunhofer Institut Angewandte Festkörperphysik (IAF), Freiburg (Germany) and the Centro Astronómico de Yebes, of the Instituto Geográfico Nacional (Spain). It has designed and developed the 30 and 44 GHz Back End Modules for the Planck mission and also has developed the 31 receivers at 30 GHz for QUIJOTE Thirty GHz Instrument (TGI). The DICOM contribution is fundamental for the development of the low noise receivers needed to reach the unprecedented level of sensitivity of QUIJOTE Phase II, for which DICOM, in collaboration with IFCA and IAC, is expected to provide the whole 31 receivers at 40 GHz for the Forty GHz Instrument (FGI).

Granada Group

THE GRANADA GROUP, led by E. Battaner, contributes with its expertise about Galactic magnetic fields and foregrounds as well as primordial magnetic fields. Its contribution will be crucial to characterize and remove the Galactic foregrounds from the cosmological signal. Besides it will make the connection between the predictions of primordial magnetic fields, appearing in different inflationary and non-inflationary scenarios, on the CMB temperature and polarization and the Planck and QUIJOTE data. The frequency coverage of the QUIJOTE Phases I + II is ideal for detecting/constraining primordial magnetic fields, through the frequency dependence of the Faraday rotation. The role that is expected to be played by the Granada group (which is well recognised in the Planck collaboration in this respect), will be crucial to achieve an optimal scientific exploitation.

Theory Group

THE THEORY GROUP, led by R. Lazkoz, has a considerable expertise in theoretical and fundamental physics. The scientific interest of the group includes the fundamental physics of inflation, the observable consequences of the inflationary period on the CMB, the nature of dark energy and dark matter, cosmological models in the framework of General Relativity and gravitational waves. Their contribution will be essential in order to establish the link between observation and fundamental physics at the inflation epoch.

Cambridge Group

THE CAMBRIDGE GROUP, led by M.P. Hobson, is also well versed in all the levels of CMB experiments, from instrument design to advanced data analysis. Besides, it contributes to the project with the Polarised Source Subtractor, an upgraded version of the VSA subtractor facility that will need to be adapted to 42 GHz in the Phase II of the experiment. The Source Subtractor is indispensable in order to remove the strong contamination of extragalactic point sources to the cosmological E and (specially) B modes. The Cambridge team is expert in fundamental physics, data analysis (including Bayesian component separation, source extraction and parameter estimation) and instrumentation. Regarding the pathfinder, the Cambridge group will participate in the design of the interferometer as well as in the study of the feasibility of the digital correlator. The Cambridge team has a wide experience in the development and operation of interferometers in the microwave range (CAT, VSA, AMI).

Manchester Group

THE MANCHESTER GROUP, led by L. Piccirillo, excels in instrumentation, with a broad experience on Low Noise Amplifier design and development. It has provided the front-end modules of the low frequency radiometers of Planck and plays a similar role in the QUIJOTE Phase I. Regarding QUIJOTE Phase II, Manchester will play a major role in the design, the construction and operations of the interferometer pathfinder. The Manchester group has a wide experience in the development of interferometers in the microwave range (VSA, JBO-IAC 33 GHz). The Manchester team has led the design of two "horns-only" bolometric interferometer arrays (MBI and QUBIC) and the EPIC-W US B-mode satellite, thus gaining a huge amount of experience that will be immediately used in the EPI pathfinder. Finally, Manchester has a solid theory group and is al so deeply involved in the development and application of diffuse and discrete component separation methods.
