Description
For circumstellar systems with an orientation perpendicular to the plane of the sky, and under some simplifying assumptions, the surface brightness integral equation can be formally inverted. Application of the resulting equation to the disk of dust surrounding the star β Pictoris seems to reveal a radial distribution of dust going approximately like 1/r. The dynamical significance of a spatial density of this kind is briefly discussed.

    Context. One way to constrain the evolutionary histories of galaxies is to analyse their stellar populations. In the local Universe, our understanding of the stellar population properties of galaxies has traditionally relied on the study of optical absorption and emission-line features. Aims. In order to overcome limitations intrinsic to this

    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 such, superclusters are a smaller version of the cosmic web and can hence be considered as miniature universes. In addition to the galaxies, superclusters also contain gas, which is hot in
