The Cosmic Microwave Background (CMB) radiation was released when the universe was only 380,000 years old, and since then it has been propagating through the entire visible universe until reaching us. In its journey, the CMB witnesses how the first stars formed, contaminating the inter galactic medium with the first heavy elements, how the Large Scale Structure (LSS) was assembled through gravitational interaction and how the universe has recently entered a phase of accelerated expansion. All these episodes have left their imprint on the intensity and polarization anisotropies of the CMB, by means of either resonant or Compton scattering, atomic and molecular collision emission processes, and blue/red-shifting induced by gravitational potential wells in the LSS. Therefore, a joint study of CMB and LSS constitutes a crucial tool for understanding those largely unknown episodes, and goes timely with the outcome of CMB experiments like ACT or PLANCK, and LSS surveys like BOSS, J-PAS or EUCLID, in which the candidate is participating. Here we propose a combined study of the optical data to be provided in the next few years by the J-PLUS/J-PAS surveys with CMB multifrequency maps (either from WMAP or those being currently produced by PLANCK): our goal is to address the problems associated to Dark Energy and the accelerated expansion of the universe (by looking at the Integrated Sachs-Wolfe effect and the galaxy cluster/group abundance versus redshift), the universal thermal history and the search for the local missing baryons (by cross correlating the electron distribution traced by galaxy catalogs with CMB maps). The timing of this project fits perfectly with the analysis and data release of both J-PLUS and PLANCK surveys, and provides both data legacy and expertise in preparation for the european space mission EUCLID.
