    Galactic population of radio and gamma-ray pulsars
    We simulate the characteristics of the Galactic population of radio and gamma-ray pulsars using Monte Carlo techniques. At birth, neutron stars are spatially...

    GRB 070610: Flares from a peculiar Galactic source
    The majority of bright gamma-ray transients that we observe in the sky, are produced by extragalactic gamma-ray bursts (GRBs). However, we know that there are...

    GRB 080514B: the first high-energy AGILE burst with optical/NIR afterglow
    The AGILE gamma-ray burst GRB 080514B was the first detected to have emission at energies above 30 MeV and an optical/NIR afterglow. Here we summarize the main...
