    VRIJHK photometry of SN 2002cv (Elias-Rosa+, 2008)
    The fact that another SN Ia, SN 2002bo, exploded in the same galaxy a few months before SN 2002cv, makes available pre-discovery optical and near-IR (NIR) data...

    Where does galactic dust come from?
    Here we investigate the origin of the dust mass (Mdust) observed in the Milky Way (MW) and of dust scaling relations found in a sample of local galaxies from...

    XMM-Newton-discovered Fast X-ray Transients: host galaxies and limits on contemporaneous detections of optical counterparts
    Extragalactic fast X-ray transients (FXTs) are a class of soft (0.3-10 keV) X-ray transients lasting a few hundred seconds to several hours. Several progenitor...
