    Origin of stellar prolate rotation in a cosmologically simulated faint dwarf galaxy
    Stellar prolate rotation in dwarf galaxies is rather uncommon, with only two known galaxies in the Local Group showing such feature (Phoenix and And II)...

    Origin of the X-ray background and AGN unification: new perspectives
    We critically review the basic assumptions of the standard model for the synthesis of the X-ray background (XRB) in the light of new data from ultradeep surveys...
