    Characterization of DESI fiber assignment incompleteness effect on 2-point clustering and mitigation methods for DR1 analysis
    We present an in-depth analysis of the fiber assignment incompleteness in the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1). This...

    CosmoMIA: cosmic web-based redshift space halo distribution
    Modern galaxy surveys demand extensive survey volumes and resolutions surpassing current dark matter-only simulations' capabilities. To address this, many...

    DESI 2024 IV: Baryon Acoustic Oscillations from the Lyman alpha forest
    We present the measurement of Baryon Acoustic Oscillations (BAO) from the Lyman-α (Lyα) forest of high-redshift quasars with the first-year dataset of the Dark...

    DESI Observations of the Andromeda Galaxy: Revealing the Immigration History of Our Nearest Neighbor
    We present Dark Energy Spectroscopic Instrument (DESI) observations of the inner halo of M31, which reveal the kinematics of a recent merger-a galactic...

    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...

    Identifying Missing Quasars from the DESI Bright Galaxy Survey
    The Dark Energy Spectroscopic Instrument (DESI) cosmology survey includes a Bright Galaxy Survey (BGS), which will yield spectra for over 10 million bright...

    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...

    Relativistic angular redshift fluctuations embedded in large scale varying gravitational potentials
    We compute the linear order, general relativistic corrections to angular redshift fluctuations (ARF), a new cosmological observable built upon density-weighted...
