Cotton double copy for gravitational waves

چکیده
We construct a double copy relation between the Cotton spinor and dual field strength of topologically massive theories, as three-dimensional analog Weyl copy. The relationship holds in curved backgrounds for wave solutions. give an explicit proof type N spacetimes show examples satisfying

Gravitational Waves from Gravitational Collapse
Gravitational wave emission from stellar collapse has been studied for more than three decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular momentum profiles, properly treat microphysics issues, account for general relativity, and examine non-axisymmetric effects in three dimensions. Such simulations predict that g...
متن کاملGravitational lensing by gravitational waves
Gravitational lensing by gravitational wave is considered. We notice that although final and initial direction of photons coincide, displacement between final and initial trajectories occurs. This displacement is calculated analytically for the plane gravitational wave pulse. Estimations for observations are discussed.
متن کاملGravitational Waves
This article reviews current efforts and plans for gravitational-wave detection, the gravitationalwave sources that might be detected, and the information that the detectors might extract from the observed waves. Special attention is paid to (i) the LIGO/VIRGO network of earth-based, kilometer-scale laser interferometers, which is now under construction and will operate in the highfrequency ban...
متن کاملThe Search for Gravitational Waves
The basic physics of g.w.'s emission, propagation and detection is outlined. The general features of candidate sources and detectors are discussed, showing how astrophysical emission events could be detected by devices not far from their Standard Quantum Limit. Two kinds of ground based detectors currently under active development, Km size interferometers and mK cold massive mechanical resonato...
متن کاملCosmological Waveguides for Gravitational Waves
We study the linearized equations describing the propagation of gravitational waves through dust. In the leading order of the WKB approximation, dust behaves as a nondispersive, non-dissipative medium. Taking advantage of these features, we explore the possibility that a gravitational wave from a distant source gets trapped by the gravitational field of a long filament of galaxies of the kind s...
