    Globular clusters as a dynamical probe of dark matter
    Gravitational dynamical friction affecting the orbits of globular clusters (GCs) was studied extensively as a possible formation mechanism for nuclear star...

    How to use a cosmological N-body simulation as a theoretical model
    A key problem that we are facing in cosmology nowadays is that we cannot make accurate predictions with our current theoretical models. We have all of the...

    How well does galaxy clustering constrain cosmology?
    On the LCDM cosmology, dark matter collapses into virialised objects called haloes. The abundance and distribution of these haloes are a direct consequence of...

    Matter-antimatter sourced dark matter
    Cosmological and astrophysical e xperimental data demark a large share of the limits of our knowledge in fundamental physics. I'll review two pieces of evidence...

    The dark side
    What's the dark matter made of? Do we have any idea of the kind of particle that should constitute ~85% of the matter content of the Universe? In this talk, I...
