    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...

    The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: measuring growth rate and geometry with anisotropic clustering
    We use the observed anisotropic clustering of galaxies in the Baryon Oscillation Spectroscopic Survey Data Release 11 CMASS sample to measure the linear growth...

    The correlation structure of dark matter halo properties
    We investigate the correlation between nine different dark matter halo properties using a rank correlation analysis and a Principal Component Analysis for a...
