While this interface document proposes technical standards for numerical relativity waveforms, we believe that the ability to extract the best astrophysical information from NR waveforms in gravitational wave searches will depend not just on adopting standards, but on the ability of the gravitational wave detector communities and the NR relativity communities to interact closely and develop a s...
Various models for electromagnetic emissions correlated with the gravitational wave signals expected to be detectable by the current and planned gravitational wave detectors are studied. The position error on the location of a gravitational wave source is estimated, and is used to show that it could be possible to observe the electromagnetic counterparts to neutron star-neutron star or neutron ...
The propagation of a gravitational wave (GW) through a magnetized plasma is considered. In particular, we study the excitation of fast magnetosonic waves (MSW) by a gravitational wave, using the linearized general-relativistic hydromagnetic equations. We derive the dispersion relation for the plasma, treating the gravitational wave as a perturbation in a Minkowski background space-time. We show...
The gravitational wave solutions obtained from a perturbation about conformally flat backgrounds in Einstein gravity are investigated. A perturbation theory analysis of the Lesame, Ellis and Dunsby results, based on a covariant approach, shows that for gravitational waves interacting with irrotational dust, the equations are linearization unstable. The gravitational wave equations based on the ...
The paper is excellent and of necessary relevance to the field of gravitational wave astronomy. The author derives and discusses an important, novel way to calculate the estimated gravitational wave power from an astronomical system using a new novel interpretation for the moment of inertia term inside the kernel of Einstein's power equation. This new method reduces the complexity and greatly s...
Large gravitational wave interferometric detectors, like Virgo and LIGO, demonstrated the capability to reach their design sensitivity, but to transform these machines into an effective observational instrument for gravitational wave astronomy a large improvement in sensitivity is required. Advanced detectors in the near future and third-generation observatories in more than one decade will ope...
We describe a method by which gravitational wave observations of eccentric binary systems could be used to test General Relativity’s prediction that gravitational waves are dispersionless. We present our results in terms of the graviton having a non-zero rest mass, or equivalently a non-infinite Compton wavelength. We make a rough estimate of the bounds that might be obtained following gravitat...
