    The Dust and [C II] Morphologies of Redshift ∼4.5 Sub-millimeter Galaxies at ∼200 pc Resolution: The Absence of Large Clumps in the Interstellar Medium at High-redshift
    We present deep, high-resolution (0.″03, 200 pc) ALMA Band 7 observations covering the dust continuum and [C II] λ157.7 μm emission in four z ∼ 4.4–4.8 sub...

    The dust content of high-z submillimeter galaxies revealed by Herschel
    We use deep observations taken with the Photodetector Array Camera and Spectrometer (PACS), on board the Herschel satellite as part of the PACS evolutionary...

    The dust masses of powerful radio galaxies: clues to the triggering of their activity
    We use deep Herschel Space Observatory observations of a 90 per cent complete sample of 32 intermediate-redshift 2Jy radio galaxies (0.05 z 0.7) with strong...

    The dust morphology of the elliptical Galaxy M 86 with SPIRE
    We present Herschel-SPIRE observations at 250-500 μm of the giant elliptical galaxy M 86 and examine the distribution of the resolved cold dust emission and its...

    The dust-gas AGN torus as constrained from X-ray and mid-infrared observations
    Context. In recent decades, several multiwavelength studies have been dedicated to exploring the properties of the obscuring material in active galactic nuclei...

    The dusty tori of nearby QSOs as constrained by high-resolution mid-IR observations
    We present mid-infrared (MIR; 7.5-13.5 μm) imaging and spectroscopy observations obtained with the CanariCam (CC) instrument on the 10.4-m Gran Telescopio...

    The dwarf galaxy population in nearby clusters from the KIWICS survey
    We analyse a sample of 12 galaxy clusters, from the Kapteyn IAC WEAVE INT Cluster Survey (KIWICS) looking for dwarf galaxy candidates. By using photometric data...

    The dynamical and chemical evolution of dwarf spheroidal galaxies
    We present a large sample of fully self-consistent hydrodynamical Nbody/Tree-SPH simulations of isolated dwarf spheroidal galaxies (dSphs). It has enabled us to...

    The dynamical state of bars in cluster dwarf galaxies: the cases of NGC 4483 and NGC 4516
    Dwarf barred galaxies are the perfect candidates for hosting slowly rotating bars. They are common in dense environments and have a relatively shallow potential...
