    Families of galaxies in the mu(e)-R(e) plane
    On the basis of a sample of Virgo cluster galaxies in a larger set of heterogeneous literature data, it is shown that ellipticals, early-type dwarfs, and bulges...

    Flares, Warps, Truncations, and Satellite: The Ultra-thin Galaxy UGC 11859
    The structure of the outskirts of galaxies provides valuable information about their past and evolution. Due to their projected orientation, edge-on isolated...

    Galaxies Going Bananas: Inferring the 3D Geometry of High-redshift Galaxies with JWST-CEERS
    The 3D geometries of high-redshift galaxies remain poorly understood. We build a differentiable Bayesian model and use Hamiltonian Monte Carlo to efficiently...

    Globular cluster systems and the origin of early-type dwarfs in Virgo
    Early-type dwarfs (dEs) are by far the most abundant galaxy population in nearby clusters. Whether these objects are primordial, or recent end-products of the...

    H II regions in Sextans A
    CCD narrow-band H-alpha photometry of the Sextans A Local Group dwarf irregular galaxy is presented. Fourteen H II regions have been recorded. Their...

    Impact of internal bremsstrahlung on the detection of γ rays from neutralinos
    We present a detailed study of the effect of internal bremsstrahlung photons in the context of the minimal supersymmetric standard models and their impact on γ...

    Infrared Properties of Star Forming Dwarf Galaxies
    Dwarf galaxies are the most common galaxies in the Universe. They are systems believed to consist of matter in a near-primordial state, from which giant...
