    Type Ia supernovae with and without blueshifted narrow Na I D lines - how different is their structure?
    In studies on intermediate- and high-resolution spectra of Type Ia supernovae (SNe Ia), some objects exhibit narrow Na I D absorptions often blueshifted with...

    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...
