Gravitational Waves and Gravitational Wave Detectors
2020Just over 100 years ago, Albert Einstein published his General Theory of Relativity, which describes the interaction between matter, energy, space, and time and explains that the force of gravity is a result of the curvature of space and time (Einstein in Die feldgleichungen der gravitation.

Abstract The theory of weak gravitational waves is discussed at length. The transverse traceless gauge is described, and the behaviour of plane wave solutions obtained. The impact of a wave on physical objects, and hence methods for their detection, are calculated.

NOWHERE should the nonlinear features of general relativity show up more clearly than in the collisional interaction of two gravitational waves. One of the direct consequences of the linearity of Maxwell's equations is that electromagnetic waves pass straight through each other, and this is probably one of the best attested facts of physics.

The X-ray counterpart to the gravitational-wave event GW170817
Nature, 2017A long-standing paradigm in astrophysics is that collisions—or mergers—of two neutron stars form highly relativistic and collimated outflows (jets) that power γ-ray bursts of short (less than two seconds) duration.

Introduction Gravitational waves are a consequence of Einstein’s General Theory of Relativity, first presented in 1915 and published in 1916 [1]. Einstein himself linearized his theory and derived wave equations and calculated the gravitational radiation produced by sources in the weak-field, slow-motion limit [2]. As described in the following Chapter,

Gravitational waves may reach the Earth in different forms which depend on the nature of the emitting source: they may be short bursts, outcome of a catastrophic event like the gravitational collapse or the coalescence of a binary system; they may be continuous, weak wavetrains emitted by a non axially symmetric, rotating neutron star or by binary ...

The effort to develop suspended mass interferometers for gravitational wave detection has lead to an ambitious new set of long baseline interferometers that will soon become operational. These detectors are based on the effect of a propagating gravitational wave to deform space in a quadrupolar form. The characteristics of the deformation are indicated
