    Star formation modes and population gradients in simulated dwarf galaxies
    Today we largely understand the large scale evolution of the Universe but we have only little knowledge of the small scale physics involved in forming and...

    Tales from the Milky Way's dwarf galaxies
    The immediate surroundings of our Milky Way galaxy are home to a number of dwarf galaxies, whose variety in shape, size, spatial location and velocity tells us...

    The distance to the Pegasus Dwarf Irregular Galaxy: an open question
    The distance of the Pegasus Dwarf Irregular Galaxy is discussed in the light of new, deep photometry of the resolved stars taken in the bands V, R, and I of the...

    The Fast X-Ray Transient XRT 210423 and Its Host Galaxy
    Fast X-ray Transients (FXTs) are X-ray flares with durations ranging from a few hundred seconds to a few hours. Possible origins include the tidal disruption of...

    The Impact of Dwarf-Dwarf Galaxy Tidal Interactions
    Two competing effects appear to govern galaxy multiplicity (pairs orgroups) at low masses: while associations of low-mass haloes are naturally expected in a...
