Gravity Wave Watching
It is suggested that gravity waves could, in several cases, be detected by means of already (or shortly to be) available technology, independently of current efforts of detection. The present is a follow-up on a recently suggested detection strategy based on gravity-wave-induced deviations of null geodesics. The new development is that a way was found to probe the waves close to the source, whe...
متن کاملWatching a Travelling Wave Watching a Travelling Wave
Travelling waves are a feature of many spatio-temporal series. The use of single side band filtering and the complex singular value decomposition to isolate such waves is described. As with other applications of the singular value decomposition, such as principal components, the results can be difficult to interpret. In the case of travelling waves, however, a dynamic graphical display using co...
متن کاملGravity Wave Lensing
Here we show that a nonlinear resonance between oceanic surface waves caused by small seabed features (the so called Bragg resonance) can be utilized to create equivalent of lenses and curved mirrors for surface gravity waves. Such gravity wave lenses, which are merely small changes to the seafloor topography and therefore are surface non-invasive, can focus/defocus energy of incident waves tow...
متن کاملA Macroscopic Gravity Wave Effect
Gravitational waves, although generally associated with extremely microscopic effects, can displace by hundreds of kilometers the pulsar interstellar scintillation patterns that bathe the Earth. The combination of the pulsar and the interstellar medium acts as a kiloparsec-long, nature-provided gravity wave amplifier. We show how an effective scheme for the detection of periodic gravity waves c...
متن کاملGravity wave turbulence in wave tanks: space and time statistics.
We present the first simultaneous space-time measurements for gravity wave turbulence in a large laboratory flume. We found that the slopes of k and omega wave spectra depend on wave intensity. This cannot be explained by any existing theory considering wave turbulence as the result of either breaking events or weakly nonlinear wave interactions. Instead, we show that random waves and breaking ...
