    Extremely Red Galaxies at z = 5–9 with MIRI and NIRSpec: Dusty Galaxies or Obscured Active Galactic Nuclei?
    We study a new population of extremely red objects (EROs) recently discovered by the James Webb Space Telescope (JWST) based on their NIRCam colors F277W ‑...

    Formation and evolution of double-barred galaxies
    The general picture of galaxy formation and evolution includes bars as the main drivers of the internal secular processes affecting the lifetime of disc...

    From the blue cloud to the red sequence (and over the green valley): investigating the evolution of galaxies over cosmological timescales
    In the local universe, galaxies fall into one of two populations: a star-forming blue cloud and a red sequence lacking star formation. At redshift z ~ 1.5...

    Galactic Globular Clusters: Why should we care about them?
    Galactic globular clusters have always been at the crossroad of several investigations in both Stellar and Galactic Astrophysics. For long time, they have been...
