In this article we summarise the proceedings of the Workshop on Gravitational Waves held during ICGC-95. In the first part we present the discussions on 3PN calculations (L. Blanchet, P. Jaranowski), black hole perturbation theory (M. Sasaki, J. Pullin), numerical relativity (E. Seidel)...
We study the generation of gravitational radiation by sources moving in the de Sitter background. A gauge is chosen in which all the physical and unphysical modes of the graviton correspond to minimally coupled massless scalar fields in de Sitter space-time and massless scalar fields in Minkowski...

Numerical modeling of seismic and acoustic-gravity waves propagation in an “Earth-Atmosphere” model in the presence of wind in the air In this paper, an effective numerical algorithm for 2.5D seismic and acoustic-gravitational wave propagation is applied to a combined “Earth-Atmosphere” ... ...
Future detectors will be able to measure gravitational waves at frequencies lower than the current cut-off ~10 Hz, ‘because that’s where the signals from collisions of black holes are lurking,’ van Heijningen explains. But one of the main issues of these huge detectors is that they need...
The problems of the generation and detection of gravitational waves and the difficulty of detecting the burst of gravitational radiation produced by a stellar collapse in our Galaxy, or in neighbouring clusters of galaxies where such collapses are expected to occur frequently, have been reviewed ...
The recent detections of gravitational waves (GWs) reported by the LIGO and Virgo collaborations have made a significant impact on physics and astronomy. A global network of GW detectors will play a key role in uncovering the unknown nature of the source
A model is introduced which describes the baroclinic generation of internal gravity waves in the water column overlying an abyssal overflow in which bottom friction, rotation and down slope gravitational acceleration are all present. A brief description is given of the internal waves associated with ...
Gravitational wave astronomy is a new and exciting field but has a long history as well as a bright future. The first detections of gravitational waves were from instruments of the second generation of detectors – the first generation of kilometer-scale ground based detectors operated as planned,...
