    Herschel-SPIRE observations of the disturbed galaxy NGC 4438
    We present Herschel-SPIRE observations of the perturbed galaxy NGC 4438 in the Virgo cluster. These images reveal the presence of extra-planar dust up to ~4-5...

    High spatial resolution Galactic 3D extinction mapping with IPHAS
    We present an algorithm (MEAD, for `Mapping Extinction Against Distance') which will determine intrinsic (r' - i') colour, extinction, and distance for early-A...

    High-resolution Optical Spectroscopy of DY Cen: Diffuse Interstellar Bands in a Proto-fullerene Circumstellar Environment?
    We search high-resolution and high-quality VLT/UVES optical spectra of the hot R Coronae Borealis star DY Cen for electronic transitions of the C60 molecule and...

    High-spatial resolution SED of NGC 1068 from near-IR to radio. Disentangling the thermal and non-thermal contributions
    We investigate the idea that a sizable fraction of the interferometrically unresolved infrared emission of the nucleus of NGC 1068 might originate from...

    Hydrogenated fulleranes and the anomalous microwave emission of the dark cloud LDN 1622
    We study the rotation rates and electric dipole emission of hydrogenated icosahedral fullerenes under the physical conditions of the dark cloud (DC) LDN 1622...

    Iron abundance and dust in galactic H II regions.
    The [Fe II] and [Fe III] emission of seven galactic H II regions is studied with the aim of comparing their gaseous Fe abundance. The [Fe II] line intensity...

    Iron Depletion in Ionized Nebulae of the Large Magellanic Cloud
    We present here preliminary results of an analysis of the iron abundance in the ionized gas of three planetary nebulae and one H II region of the Large...

    JWST view of Polycyclic Aromatic Hydrocarbons and dust in local active galaxies
    Nowadays, it is widely accepted that most galaxies undergo an active phase in their evolution. The impact of the energy released by active galactic nuclei (AGN)...
