    Light-curve models for a pulsar orbiting a Kerr black hole
    We have studied the signal received by a distant observer from a pulsar orbiting a stellar black hole. The binary system has a non-eccentric orbit and the most...

    Like two strangers: Quantum Mechanics and General Relativity
    General Relativity just turned 100 years old. Quantum Mechanics is 10 years younger. They both enjoy excellent health and, together, have produced a prolific...

    Matters of gravity
    Contrary to popular belief, on very large distance scales visible matter stubbornly refuses to "fall" according to the laws of gravity of both Newton and...

    Phase space distribution of halo particles and detection of WIMPS
    We calculate the velocity distribution of halo particles using realistic models for the density profiles of the Galactic disk, spheroid, and halo components. We...

    Probing the early Universe with gravitational Wave Background
    We will review both theoretical and obsevational aspects of gravitational wave backgrounds of cosmological origin. We will present a classifcation of...

    The influence of microlensing on spectral line shapes generated by a relativistic accretion disc
    We study the influence of gravitational microlensing on the spectral line profiles originating from a relativistic accretion disc. Using the Chen & Halpern...

    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...
