Astrophysical: Reionization

  • Publication
    Gran Telescopio Canarias observations of an overdense region of Lyman α emitters at z = 6.5
    We present the results of our search near the end of the Reionization Epoch for faint galaxies. This has been done using very deep OSIRIS images obtained at the...
  • Publication
    High-z galaxies behind the lensing cluster A2667
    We have conducted a survey aimed at identifying a sample of z˜7-10 candidates accessible to detailed spectroscopic studies. The deep survey on A2667 covers a...
  • Publication
    Lyman continuum leaker candidates at z ∼ 3-4 in the HDUV based on a spectroscopic sample of MUSE LAEs
    Context. In recent years, a number of Lyman continuum (LyC) leaker candidates have been found at intermediate redshifts, providing insight into how the Universe...

    Lyα Emitting Galaxies (LAEs) at Cosmic Dawn: Implications and Predictions
    The detection of Lyα emitting galaxies (LAEs) puts severe constraints on the reionization history. In this paper, we derive the properties of very high-z LAEs...
  • Publication
    MOS spectroscopy of protocluster candidate galaxies at z = 6.5
    The epoch corresponding to a redshift of z ̃ 6.5 is close to full re-ionization of the Universe, and early enough to provide an intriguing environment to...
  • Publication
    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...
  • Publication
    Optical dropout galaxies lensed by the cluster A2667
    Context. We investigate the nature and the physical properties of ten z, Y, and J-dropout galaxies selected in the field of the lensing cluster A2667. Aims...

    Planck intermediate results. XLVI. Reduction of large-scale systematic effects in HFI polarization maps and estimation of the reionization optical depth
    This paper describes the identification, modelling, and removal of previously unexplained systematic effects in the polarization data of the Planck High...
  • Publication
    Planck intermediate results. XLVII. Planck constraints on reionization history
    We investigate constraints on cosmic reionization extracted from the Planck cosmic microwave background (CMB) data. We combine the Planck CMB anisotropy data in...
