    The limit of mass for gravitational collapse and nuclear forces at short distance
    On the basis of the current knowledge about the size of the neutron, the nucleon-nucleon interaction, and the limit on the ratio Gm/c2R 4/9 imposed by General...

    The Mass of the Neutron Star in CYG X-2 (V1341 CYG)
    Cygnus X-2 is one of the brightest and longest known X-ray sources. We present high resolution optical spectroscopy of Cyg X-2 obtained over 4 years which gives...

    The Mass of the X-ray Pulsar in X1822-371
    We have computed the K-correction for emission lines formed on the irradiated face of the companion stars in X-ray binaries. Our results, combined with the...

    The Neutron Star Circus: Accretion Flows and Thermonuclear Bursts
    Neutron stars in low-mass X-ray binaries (NS-LMXBs) are unique laboratories of accretion physics, strong gravity and ultra-dense matter. I will give an overview...

    The neutron star transient SAX J1810.8-2609 going back to quiescence
    We observed the neutron star transient SAX J1810.8-2609 with Swift-XRT on November 3rd and 5th, in order to follow its way to quiescence. The source was not...

    The NIR counterpart to XTE J1747-274(=IGR J17473-2721)
    We report follow-up observations confirming the near-infrared (NIR) counterpart to the X-ray transient XTE J1747-274/IGR J17473-2721 (ATEL #467, #498). A Ks=16...

    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 Rotation Speed of the Companion Star in Aquila X-1
    We have obtained medium resolution spectra of the neutron star X-ray transient Aql X-1 during quiescence. We determine the spectral type of the companion star...

    The Third Fermi Large Area Telescope Catalog of Gamma-Ray Pulsars
    We present 294 pulsars found in GeV data from the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. Another 33 millisecond pulsars (MSPs)...
