    Discriminating between unresolved point sources and `negative' Sunyaev-Zel'dovich clusters in cosmic microwave background maps
    Clusters of galaxies produce negative features at wavelengths λ > 1.25 mm in cosmic microwave background (CMB) maps by means of the thermal Sunyaev-Zel'dovich...

    Disentangling the formation history of galaxies via population-orbit superposition: method validation
    We present population-orbit superposition models for external galaxies based on Schwarzschild's orbit-superposition method, by tagging the orbits with age and...

    Disentangling the nature of the prototype radio weak BL Lac. Contemporaneous multifrequency observations of WISE J141046.00+740511.2
    Context. The γ-ray emitting source WISE J141046.00+740511.2 has been associated with a Fermi-LAT detection by crossmatching with Swift/XRT data. It has shown...

    Disruption of satellite galaxies in simulated groups and clusters: the roles of accretion time, baryons, and pre-processing
    We investigate the disruption of group and cluster satellite galaxies with total mass (dark matter plus baryons) above 10^{10} M_⊙ in the Hydrangea simulations...
  • Publication
    Dissecting a miniature universe: A multi-wavelength view of galaxy quenching in the Shapley supercluster
    Multiple cluster systems, that is superclusters, contain large numbers of galaxies assembled in clusters interconnected by multi-scale filamentary networks. As...

    Dissecting Early-type Dwarf Galaxies into Their Multiple Components
    Early-type dwarf galaxies, once believed to be simple systems, have recently been shown to exhibit an intriguing diversity in structure and stellar content. To...
  • Publication
    Dissecting galactic bulges in space and time - I. The importance of early formation scenarios versus secular evolution
    The details of bulge formation via collapse, mergers, secular processes or their interplay remain unresolved. To start answering this question and quantify the...
  • Publication
    Dissecting the cosmic infra-red background with Herschel/PEP
    The constituents of the cosmic IR background (CIB) are studied at its peak wavelengths (100 and 160 μm) by exploiting Herschel/PACS observations of the GOODS-N...

    Dissecting the long-term emission behaviour of the BL Lac object Mrk 421
    We report on long-term multiwavelength monitoring of blazar Mrk 421 by the GLAST-AGILE Support Program of the Whole Earth Blazar Telescope (GASP-WEBT)...
