    Galaxy disc heating as a result of minor mergers
    We perform a sample of N-body simulations of a minor merger between a Milky Way type galaxy and a satellite, which is density scaled version of the primary...

    Growth of galactic bulges by mergers. II. Low-density satellites
    Context: .Satellite accretion events have been invoked for mimicking the internal secular evolutionary processes of bulge growth. However, N-body simulations of...

    Harassment origin for kinematic substructures in dwarf elliptical galaxies?
    We have run high resolution N-body models simulating the encounter of a dwarf galaxy with a bright elliptical galaxy. The dwarf absorbs orbital angular momentum...

    Modeling Tidal Streams in Evolving Dark Matter Halos
    We explore whether stellar tidal streams can provide information on the secular, cosmological evolution of the Milky Way's gravitational potential and on the...

    Non-instantaneous gas recycling and chemical evolution in N-body disk galaxies
    After briefly recalling basic facts about the metallicity gradients inspiral galaxies, we summarize two recent N-body gas-dynamical modelsthat implement a non...

    SkyMAD: Building galaxy mock catalogs for large surveys
    The accelerated expansion of the Universe discovered in the late 90's has opened one of the most intriguing questions of modern physics. To help to understand...

    Spin alignment of dark matter haloes in the shells of the largest voids
    Using the high-resolution cosmological N-body simulation MareNostrum universe we study the orientation of shape and angular momentum of galaxy-size dark matter...

    Stability and formation of the resonant system HD 73526
    Context: Based on radial velocity measurements, it has been found that the two giant planets detected around the star HD 73526 are in 2:1 resonance. However, as...
