Things should be made simple, but not simpler. What we want to show is that General Relativity, as it stands today, can be considered as a gravitational theory...

PublicationA pulse-timing model for pulsars in massive eclipsing binaries. Delays caused by high ratios between the pulsar period and orbital length.
We study the delay induced by gravitational light bending in the arrival times of signals emitted by an anisotropic source in rotation (pulsar). The shift of...

PublicationA second-order approximation to equatorial null geodesics in the Kerr metric - Application to light deflection in eclipsing compact binaries
We present a second-order analytical expansion of null equatorial geodesics in the Kerr metric. The equations developed are applied to the study of light...

PublicationChandra and RXTE spectroscopy of the Galactic microquasar XTE J1550-564 in outburst
On two occasions, we obtained nearly simultaneous ~=4 ks snapshot observations of the Galactic black hole and microquasar XTE J1550-564 with Chandra and RXTE...

PublicationConstraints on the cosmic equation of state: Age conflict versus phantom energy. Age-redshift relations in an accelerated universe
The currently available values and confidence limits for Ωm0, H0 and globular cluster ages still indicate that the dark energy that dominates the Universe could...

PublicationDynamical effects of radiation on the orbits of bodies in the Schwarzschild metric. I
Dynamical problems associated with the orbital motion of dust particles in strong gravitational and radiation fields are analyzed. The general relativistic...

PublicationGeneral relativistic influence on emission line variation in broad-line region
The present examination of general relativistic effect on the lag time between continuum and emission line variations in the broad line notes that in the case...

PublicationGravitational radiation from point masses in elliptical orbits: spectral analysis and orbital parameters
The amplitude of the gravitational waves emitted by a binary system of arbitrary eccentricity and orientation is developed in Fourier-Bessel series. Periastron...
