Absorption of gravitational waves from distant sources

Periodic Sources of Gravitational Waves

Gravitational Waves : Sources and Detectorss

The world wide eeorts for detecting gravitational waves, the detectors in vogue and the expected astrophysical sources of gravitational waves will be discussed. Ground based detectors especially, the resonant bar detectors and laser interferometers will be described with a brief mention of the space based detector (the LISA project). Astrophysical sources of gravitational waves such as coalesci...

Timing Effects of Gravitational Waves from Localized Sources

Localized astronomical sources like a double stellar system, rotating neutron star, or a massive black hole at the center of the Milky Way emit periodic gravitational waves. For a long time only a far-zone contribution of gravitational fields of the localized sources (plane-wave-front approximation) were a matter of theoretical analysis. We demonstrate how this analysis can be extended to take ...

Gravitational Waves from a Cosmological Distribution of Sources

The advent of gravitational wave detectors such as the Laser Interferometer Space Antenna and the Advanced-Laser Interferometer Gravitational wave Observatory will make it possible to observe many gravitational wave emission phenomena that may or may not have electromagnetic counterparts. In many cases, gravitational waves serve as probes of length and time scales that range many orders of magn...

Gravitational waves from remnants of ultraluminous X-ray sources

Ultraluminous X-ray sources (ULXs) with X-ray luminosities larger than the Eddington luminosity of stellar mass objects may be powered by intermediate mass black holes (IBHs) of masses M• ∼ 103M⊙. If IBHs form in young dense stellar clusters, they can be fed by Roche lobe overflow from a tidally captured massive (M⋆ > 10M⊙) stellar companion. After the donor leaves the main sequence it forms a ...
