    Study of the Sextans dwarf spheroidal galaxy from the DART Ca II triplet survey
    We use Very Large Telescope (VLT)/Fibre Large Array Multi Element Spectrograph (FLAMES) intermediate-resolution (R˜ 6500) spectra of individual red giant branch...

    Testing Axion Physics in a Josephson Junction Environment
    We suggest that experiments based on Josephson junctions, SQUIDS, and coupled Josephson qubits may be used to construct a resonant environment for dark matter...

    Testing the conditional mass function of dark matter haloes against numerical N-body simulations
    We compare the predicted conditional mass function (CMF) of dark matter haloes from two theoretical prescriptions against numerical N-body simulations, both in...

    The (very) small-scale structure of dark matter halos
    In our now-standard picture for the growth of structure, dark matter halos are the basic unit of nonlinear structure in the present Universe. I will report...

    The abundance of clustered primordial black holes from quasar microlensing
    While elementary particles are the favored candidate for the elusive dark matter, primordial black holes (PBHs) have also been considered to fill that role...

    The ALHAMBRA survey: Estimation of the clustering signal encoded in the cosmic variance
    Aims: The relative cosmic variance (σv) is a fundamental source of uncertainty in pencil-beam surveys and, as a particular case of count-in-cell statistics, can...

    The Alignment of Dark Matter Halos with the Cosmic Web
    We investigate the orientation of the axes and angular momentum of dark matter halos with respect to their neighboring voids using high-resolution N-body...
