    The quest for axions
    We introduce the strong CP problem and the existence of the Axion as a possible solution. We discuss the possibility that axions are the dark matter of the...

    The quest for gamma-rays in clusters of galaxies: simulations and observations
    Clusters of galaxies are expected to contain substantial population of cosmic-rays that can yield a significant high energy emission. Moreover, as they are...

    The radial velocity dispersion profile of the Galactic halo: constraining the density profile of the dark halo of the Milky Way
    We have compiled a new sample of 240 halo objects with accurate distance and radial velocity measurements, including globular clusters, satellite galaxies...

    The role of massive black hole recoil in galaxy evolution
    The coalescence of a massive black hole (MBH) binary leads to the gravitational-wave recoil of the system and its ejection from the galaxy core. We have carried...

    The SAMI-Fornax Dwarfs Survey - II. The Stellar Mass Fundamental Plane and the dark matter fraction of dwarf galaxies
    We explore the kinematic scaling relations of 38 dwarf galaxies in the Fornax Cluster using observations from the SAMI integral field spectrograph. We focus on...

    The slow evolution of dark matter halos from cusp to core naturally produces extended stellar core-like distributions
    Motivated by the observation of extended stellar cores in dark matter (DM)-dominated dwarf galaxies, this study investigates a simple mechanism by which stellar...

    The spherical collapse model with shell-crossing
    In this work, we study the formation and evolution of dark matter haloes by means of the spherical infalling model with shell-crossing. We present a framework...

    The SPLASH Survey: A Spectroscopic Analysis of the Metal-Poor, Low-Luminosity M31 dSph Satellite Andromeda X
    Andromeda X (And X) is a newly discovered low-luminosity M31 dwarf spheroidal galaxy (dSph) found by Zucker et al. in the Sloan Digital Sky Survey (SDSS; York...

    The Standard Cosmological Model
    This is the first talk of a series of four aimed to discuss about Cosmology. Here, I will review the basic concepts of the standard cosmological model, which...
