    The host galaxies of BL Lac objects in the near-infrared
    We present the results of near-infrared H band (1.65 μm) imaging of 11 BL Lac objects with redshifts ranging from z = 0.05 to 0.9. We are able to clearly detect...

    The HST/ACS star formation history of the Tucana dwarf spheroidal galaxy: clues from the horizontal branch
    We report a new star formation history for the Tucana dwarf spheroidal galaxy, obtained from a new look at a deep HST/ACS colour-magnitude diagram. We combined...
