    Microwave spectro-polarimetry of matter and radiation across space and time
    This paper discusses the science case for a sensitive spectro-polarimetric survey of the microwave sky. Such a survey would provide a tomographic and dynamic...

    Near-IR narrow-band imaging with CIRCE at the Gran Telescopio Canarias: Searching for Lyα-emitters at z ∼ 9.3
    Context. Identifying very high-redshift galaxies is crucial for understanding the formation and evolution of galaxies. However, many questions still remain, and...

    Observational Evidence for a Galaxy Overdensity/Protocluster at z=6.5
    We present the results of our search near the end of the Reionization Epoch for faint galaxies around two close, massive Lyman-α emitters (LAEs) at redshift 6.5...

    On the Pair-instability Supernova Origin of J1010+2358
    The first (Population III) stars formed only out of H and He and were likely more massive than present-day stars. Massive Population III stars in the range 140...

    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...
