Spacetime is a dynamic and elastic entity both influencing and influenced by the distribution of mass and energy that it contains. As a consequence the accelerated motion of mass and energy can generate ripples or gravitational waves in the fabric of spacetime propagating at the speed of light.

Frontiers of Physics, 2013
We are entering a new era of gravitational-wave astronomy. The ground-based interferometers have reached their initial design sensitivity in the audio band. Several upper limits have been set for anticipated astrophysical sources from the science data. The advanced detectors in the US and in Europe are expected to be operational around 2015.

The theory of General Relativity predicts that objects moving in a gravitational field should emit gravitational waves. This is analogous to the emission of electromagnetic waves by moving charged particles, but the effect is much weaker. Einstein himself at first doubted the reality of the effect, and later, although recognizing the effect, thought ...

AbstractGravitational waves, as predicted by the theory of General Relativity, have been studied theoretically for many decades. However, due to the weak coupling of gravitation with matter, it has not yet been possible to measure them directly. Up to now, we only have indirect evidence of the existence and the effect of gravitational radiation by ...

Annual Review of Astronomy and Astrophysics, 1972
The "windows" of observational astronomy have become broader. They now include, along with photons from many decades of the electromagnetic spectrum, extraterrestrial "artifacts" of other sorts: cosmic rays, meteorites, particles from the solar wind, samples of the lunar surface, and neutrinos.

The direct detection of gravitational waves announced on 11 February 2016 has opened a new window onto the universe. The gravitational wave spectrum extends from some nHz to several kHz. This chapter will firstly discuss the acoustic detectors, the first historically developed.

Towards Gravitational Wave Astronomy
2014This chapter is meant to introduce the reader to the forthcoming network of second-generation interferometric detectors of gravitational waves, at a time when their construction is close to completion and there is the ambition to detect gravitational waves for the first time in the next few years and open the way to gravitational wave astronomy.
