New Examples of Sandwich Gravitational Waves and Their Impulsive Limit
نویسندگان
چکیده
Non-standard sandwich gravitational waves are constructed from the homogeneous pp vacuum solution and the motions of free test particles in the space-times are calculated explicitly. They demonstrate the caustic property of sandwich waves. By performing limits to impulsive gravitational wave it is demonstrated that the resulting particle motions are identical regardless of the “initial” sandwich.

A Decision between Bayesian and Frequentist Upper Limit in Analyzing Continuous Gravitational Waves
Given the sensitivity of current ground-based Gravitational Wave (GW) detectors, any continuous-wave signal we can realistically expect will be at a level or below the background noise. Hence, any data analysis of detector data will need to rely on statistical techniques to separate the signal from the noise. While with the current sensitivity of our detectors we do not expect to detect any tru...
متن کاملA snapping cosmic string in a de Sitter or anti-de Sitter universe
We present and describe an exact solution of Einstein’s equations which represents a snapping cosmic string in a vacuum background with a cosmological constant Λ. The snapping of the string generates an impulsive spherical gravitational wave which is a particular member of a known family of such waves. The global solution for all values of Λ is presented in various metric forms and interpreted ...
متن کاملSmearing of chaos in sandwich pp -waves
Recent results demonstrating the chaotic behavior of geodesics in non-homogeneous vacuum pp -wave solutions are generalized. Here we concentrate on motion in nonhomogeneous sandwich pp -waves and show that chaos smears as the duration of these gravitational waves is reduced. As the number of radial bounces of any geodesic decreases, the outcome channels to infinity become fuzzy, and thus the fr...
متن کاملImpulsive waves in de Sitter and anti-de Sitter space-times generated by null particles with an arbitrary multipole structure
We describe a class of impulsive gravitational waves which propagate either in a de Sitter or an anti-de Sitter background. They are conformal to impulsive waves of Kundt’s class. In a background with positive cosmological constant they are spherical (but non-expanding) waves generated by pairs of particles with arbitrary multipole structure propagating in opposite directions. When the cosmolog...
متن کاملExact impulsive gravitational waves in spacetimes of constant curvature
Exact solutions exist which describe impulsive gravitational waves propagating in Minkowski, de Sitter, or anti-de Sitter universes. These may be either nonexpanding or expanding. Both cases in each background are reviewed here from a unified point of view. All the main methods for their construction are described systematically: the Penrose “cut and paste” method, explicit construction of cont...
