    Open questions and Non-Standard models
    I will review some theoretical ideas in Cosmology different to the standard "Big Bang": the Quasi-steady State model, Plasma Cosmology model, non-cosmological...

    Origin of space and time in a non-commutative cosmological model
    A Friedman-like cosmological model, based on noncommutative geometry, is presented. Its Planck level is totally nonlocal with no space and no time. The dynamics...

    Past, present and future of cosmic microwave background observations: implications for cosmology
    Since its discovery in 1964, the cosmic microwave background (CMB) has been one of the basic pillars of the cosmological model. However, it is only very...

    Physical Properties of a Coma-analog Protocluster at z = 6.5
    We present evidence for the discovery of a protocluster of starburst galaxies (Lyα emitters, or LAEs) near the end of the epoch of reionization. The recent...

    PISN-explorer: hunting the descendants of very massive first stars
    The very massive first stars (m > 100 $\rm M_{\odot }$) were fundamental to the early phases of reionization, metal enrichment, and supermassive black hole...

    Planck 2013 results. XVI. Cosmological parameters
    This paper presents the first cosmological results based on Planck measurements of the cosmic microwave background (CMB) temperature and lensing-potential power...

    Planck 2013 results. XXII. Constraints on inflation
    We analyse the implications of the Planck data for cosmic inflation. The Planck nominal mission temperature anisotropy measurements, combined with the WMAP...

    Planck 2013 results. XXIV. Constraints on primordial non-Gaussianity
    The Planck nominal mission cosmic microwave background (CMB) maps yield unprecedented constraints on primordial non-Gaussianity (NG). Using three optimal...

    Planck 2013 results. XXV. Searches for cosmic strings and other topological defects
    Planck data have been used to provide stringent new constraints on cosmic strings and other defects. We describe forecasts of the CMB power spectrum induced by...
