    Merger traces in the spatial distribution of stellar populations in the Fornax dSph galaxy
    We present a comprehensive and detailed study of the stellar populations of the Fornax dwarf spheroidal galaxy. We analyse their spatial distributions along the...

    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...
