    The strange case of Na I in the atmosphere of HD 209458 b. Reconciling low- and high-resolution spectroscopic observations
    Aims: We aim to investigate the origin of the discrepant results reported in the literature about the presence of Na I in the atmosphere of HD 209458 b, based...

    The structure models for galaxy clustering.
    The models for galaxy clustering in which galaxies are identified with peaks on the mass density field smoothed on an appropriate scale are plagued by some...

    The Sunyaev-Zeldovich effect in superclusters of galaxies using gasdynamical simulations: the case of Corona Borealis
    We study the thermal (tSZ) and kinetic Sunyaev-Zel'dovich (kSZ) effect associated with superclusters of galaxies using the MareNostrum (MNU) universe smoothed...

    The three hundred project: mapping the matter distribution in galaxy clusters via deep learning from multiview simulated observations
    A galaxy cluster as the most massive gravitationally bound object in the Universe, is dominated by dark matter, which unfortunately can only be investigated...
