    Dark Matter and Dark Energy in the Universe


    How does the Universe evolve? What is the geometry and topology of space? What is the matter and energy content and its connection to the overall structure? The single most impressive fact concerning our universe is that it is nearly totally composed of material of unknown nature. Roughly 95% of the total cosmic matter content is in a form that escaped so far our understanding. One third of this, the so-called dark matter, appears to reside in observable objects like galaxies and clusters of galaxies and, at least in principle, might be directly detected by laboratory experiments as well as astronomical observations. The remaining 70% of the cosmic medium seems to possess an utterly different nature: it avoids clustering and accelerates the expansion of the universe. This is the dark energy. The solutions to these puzzles will most probably lead to a new view of the cosmos and/or a new understanding of the laws of nature, in particular gravity and its relation to quantum physics. We explore both theoretical and observational aspects of this problem: dark matter contend, cosmological parameter estimation, validity of Friedman equation, non-standard equation of state, linear and non-linear growth of perturbations, standard cosmological test...

    Large scale structures in the Universe


    How do structures, such as galaxies, form in the Universe? The mystery of galaxy and cluster formation cannot be separated from the general problem of large-scale structure formation taking into account the initial conditions of matter and energy content in the Universe. Our methodology is mainly oriented towards the study of implications obtained from the theories about the origin of large structures, as well as the problems related with data acquisition and analysis, especially in the case of the new generation Virtual Observatories and Terabyte data bases. Among covered topics it is worthwhile mentioning the following: comparison of the Sunyaev-Zeldovich effect with other mass indicators, (integrated) Sachs-Wolf effect, high red-shift galactic formation and millimetric cosmology (ALMA, First, GTM/LMT, Shades, Blast, Hershel), galaxy clustering, luminosity and mass function (eg SDSS, 2dFGRS, GTC) galaxy formation models and biasing, anisotropies in the CMB temperature distribution, (eg space missions such as WMAP, Plank), the statistics of the primordial distribution of fluctuations, modeling for the growth of sctructure, reconstruction of the primordial spectrum, and its interpretation, etc.
