    The first outburst of SAX J1808.4-3658 revisited
    Data of the 1996 outburst of the single-known accreting millisecond pulsar SAX J1808.4-3658, taken with the Wide Field Cameras (WFCs) on BeppoSAX, are revisited...

    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 transient and millisecond pulsar in M28: from sub-luminous accretion to rotation-powered quiescence
    The X-ray transient IGR J18245-2452 in the globular cluster M28 contains the first neutron star (NS) seen to switch between rotation-powered and accretion...

    The Optical Counterpart of the Accreting Millisecond Pulsar SAX J1808.4-3658 in Outburst: Constraints on the Binary Inclination
    We present multiband optical/IR photometry of V4580 Sgr, the optical counterpart of the accretion-powered millisecond pulsar SAX J1808.4-3658, taken during the...

    The optical counterparts of Accreting Millisecond X-Ray Pulsars during quiescence
    Using data obtained with the ESO-Very Large Telescope, we have performed a deep optical and NIR photometric study of the fields of three Accreting Millisecond X...

    The peculiar chemical abundance of the transitional millisecond pulsar PSR J1023+0038 - Li enhancement
    Using high-resolution optical spectroscopy we determine the chemical abundance of the secondary star in the binary millisecond pulsar PSR J1023+0038. We measure...

    The spatial distribution of coalescing neutron star binaries: implications for gamma-ray bursts
    We find the distribution of coalescence times, birth rates, spatial velocities, and subsequent radial offsets of coalescing neutron stars (NSs) in various...

    The Square Kilometre Array: At the Frontiers of Astronomy, Physics, and Astrobiology
    The Square Kilometre Array is intended to be the centimeter- and meter-wavelength telescope for the 21st Century. Originally proposed as the "hydrogen telescope...

    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)...
