    On the occurrence of tidal tails in the Carina dSph
    Wide field B,V photometry of the outer regions of the Carina dwarf spheroidal galaxy is presented. Six fields were observed to a distance from the centre up to...

    On the use of field RR Lyrae as galactic probes - VI. Mixed mode RR Lyrae variables in Fornax and in nearby dwarf galaxies
    We investigate the properties of the mixed-mode (RRd) RR Lyrae (RRL) variables in the Fornax dwarf spheroidal (dSph) galaxy by using B- and V-band time series...

    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)...

    Pericentric passage-driven star formation in satellite galaxies and their hosts: CLUES from local group simulations
    Local Group satellite galaxies show a wide diversity of star formation histories (SFHs) whose origin is yet to be fully understood. Using hydrodynamical...
