    Detection of the Effect of Cosmological Large-Scale Structure on the Orientation of Galaxies
    Galaxies are not distributed randomly throughout space but are instead arranged in an intricate ``cosmic web'' of filaments and walls surrounding bubble-like...

    Determination of the anisotropy of elementary particles with the Alpha Magnetic Spectrometer on the International Space Station
    A measurement of the cosmic ray anisotropy on the arrival directions of elementary particles (electrons, positrons and protons) has been performed in galactic...

    Dipolar dark matter simulations on galaxy scales with the RAMSES code
    We numerically explore on galaxy scales the dipolar dark matter (DM) model based on the concept of gravitational polarization. This DM model has been proposed...

    Dwarf Galaxies with Central Cores in Modified Newtonian Dynamics Gravity
    Some dwarf galaxies are within the Mondian regime at all radii, i.e., the gravitational acceleration provided by the observed baryons is always below the...

    Dynamical Constraints on the Formation of NGC 4472 and Its Globular Clusters
    We present new radial velocities for 87 globular clusters around the elliptical galaxy NGC 4472 and combine these with our previously published data to create a...
