    Beyond traditional diagnostics: Identifying active galactic nuclei using spectral energy distribution fitting in DESI data
    Aims. Active galactic nuclei (AGN) are typically identified through their distinctive X-ray or radio emissions, mid-infrared (MIR) colors, or emission lines...

    Biases in galaxy cluster velocity dispersion and mass estimates in the small N<SUB>gal</SUB> regime
    Aims: We present a study of the statistical properties of three velocity dispersion and mass estimators: biweight, gapper, and standard deviation for a small...

    Binary star population of the Sculptor dwarf galaxy
    Aims: We aim to compute the binary fraction of "classical" dwarf spheroidal galaxies (dSphs) that are satellites of the Milky Way (MW). This value can offer...
