    Relative Alignment between the Magnetic Field and Molecular Gas Structure in the Vela C Giant Molecular Cloud Using Low- and High-density Tracers
    We compare the magnetic field orientation for the young giant molecular cloud Vela C inferred from 500 μm polarization maps made with the BLASTPol balloon-borne...

    Resolved observations at 31 GHz of spinning dust emissivity variations in ρ Oph
    The ρ Oph molecular cloud is one of the best examples of spinning dust emission, first detected by the cosmic background imager (CBI). Here, we present 4.5...

    Scale Lengths in Disk Surface Brightness as Probes of Dust Extinction in Three Spiral Galaxies: M51, NGC 3631, and NGC 4321
    We have measured the radial brightness distributions in the disks of three nearby face-on spiral galaxies, M51, NGC 3631, and NGC 4321 (M100), in the...

    Small-scale clustering of nano-dust grains in supersonic turbulence
    We investigate the clustering and dynamics of nano-sized particles (nano dust) in high-resolution (1024 3) simulations of compressible isothermal hydrodynamic...

    Smooth kinematic and metallicity gradients reveal that the Milky Way's nuclear star cluster and disc might be part of the same structure
    Context. The innermost regions of most galaxies are characterised by the presence of extremely dense nuclear star clusters. Nevertheless, these clusters are not...

    SN 2002cv: a heavily obscured Type Ia supernova
    We present VRIJHK photometry, and optical and near-infrared spectroscopy, of the heavily extinguished Type Ia supernova (SN Ia) 2002cv, located in NGC 3190...

    Spatially resolving the dust properties and submillimetre excess in M 33
    Context. The relative abundance of the dust grain types in the interstellar medium is directly linked to physical quantities that trace the evolution of...

    Spatially-resolved dust properties of the GRB 980425 host galaxy
    Gamma-ray bursts (GRBs) have been proposed as a tool for studying star formation in the Universe, so it is crucial to investigate whether their host galaxies...
