    Fiducial-cosmology-dependent systematics for the DESI 2024 BAO analysis
    When measuring the Baryon Acoustic Oscillations (BAO) scale from galaxy surveys, one typically assumes a fiducial cosmology when converting redshift...

    Model-independent reconstruction of UV luminosity function and reionization epoch
    We conduct a first comprehensive study of the Luminosity Function (LF) using a non-parametric approach. We use Gaussian Process to fit available luminosity data...
