CIEMAT contributions to DESI

The CIEMAT group in DESI contributes to the preparation of the scientific analysis of the data through the study of detailed simulations, and particpates in the management of the collaboration through several committees. In addition to that, CIEMAT is one of the responsible institutions for the design and construction of the Guiding, Focus adn Alignment (GFA) system of DESI. In particular, we do the full characterization of the optical filters and the programming of eectronic boards, using the correlated double sampling technique.

 

CIEMAT Participation in DES

The CIEMAT Group has designed, produced and tested a dedicated electronic Clock Board (CB) and its transition board (CBT), specially adapted to the strong requirements of DECam. It is based on the public Monsoon system, which was developed by NOAO.

We also contribute to the development of the quality control software.

From the science viewpoint, we contribute in the analysis of baryon acoustic oscillations (BAO), the magnification effect of weak lensing (MAG), the general clustering properties of galaxies through counts-in-cells (CiC) and some other cosmological probes.
