    Asteroid reflectance spectra from Gaia DR3: Near-UV in primitive asteroids
    Context. In the context of charge-coupled devices (CCDs), the ultraviolet (UV) region has mostly remained unexplored after the 1990s. Gaia DR3 offers the...

    Asteroids' reflectance from Gaia DR3: Artificial reddening at near-UV wavelengths
    Context. Observational and instrumental difficulties observing small bodies below 0.5 μm make this wavelength range poorly studied compared with the visible and...
