Experiments aimed at searching for gravitational waves from astrophysical sources have been under development for the last 40 years, but only now are sensitivities reaching the level where there is a real possibility of detections being made within the next 5 years. In this paper, a history of detector development will be followed by a description of current detectors such as LIGO, VIRGO, GEO 600, TAMA 300, Nautilus and Auriga. Preliminary results from these detectors will be discussed and… Expand
The Search for Gravitational Waves
The search for gravitational waves has reached a new era as currently a network of interferometric gravitational wave detectors is in operation around the globe at its initial target sensitivity, inExpand
The Search for Gravitational Waves: Opening a New Window into the Universe
Several ground-based interferometric detectors are now in operation to detect gravitational waves. These include the Laser Interferometric Gravitational-wave Observatory (LIGO) at two sites inExpand

A brief review of the state of the art in detector development and exploitation will be given, with particular relevance to a search for signals associated with GRBs, and plans for the future will be discussed. Expand
Long baseline gravitational wave detectors-status and developments
Abstract Gravitational waves–a prediction of Einstein’s General Relativity–are among the most elusive signals incident on the Earth. These signals–ripples in the curvature of space-time–carryExpand
Aspects of materials research for advanced and future generations of gravitational wave detectors
Gravitational waves were predicted by Einstein, in his General Theory of Relativity in 1916. These waves can be thought of as ripples in the curvature of space-time. They have not yet been directlyExpand
Finite element analysis of suspension elements for gravitational wave detectors
The existence of gravitational waves was predicted by Einstein in 1916 in his General Theory of Relativity. Gravitational waves are considered as ripples in space-time, however there has been noExpand

Abstract Currently a network of interferometric gravitational wave detectors is in operation around the globe, in parallel with existing acoustic bar-type detectors. Searches are underway aimed atExpand
At the limit of weak static fields, general relativity becomes Newtonian gravity with a potential field that falls off as inverse distance rather than a theory of Yukawa-type fields with a finiteExpand
The atomic structure and properties of mirror coatings for use in gravitational wave detectors
Gravitational waves are a prediction of Einstein's General Theory of Relativity. They can be regarded as perturbations, or ripples, in the curvature of space-time that travel at the speed of light.Expand
A Multimessenger View of Galaxies and Quasars From Now to Mid-century
In the next 30 years, a new generation of space and ground-based telescopes will permit to obtain multi-frequency observations of faint sources and, for the first time in human history, to achieve aExpand


Gravitational wave detectors
As outlined in the preceding talk by Dr Thome, there are many possible sources of gravitational radiation, ranging from the interactions of supermassive black holes to supernova explosions of stars.Expand
Optical Cavity Laser Interferometers for Gravitational Wave Detection
Most of the techniques being developed for detection of gravitational radiation involve sensing the small strains in space associated with the gravitational waves by looking for changes in theExpand
Null Search for Bursts of Gravitational Radiation
A calibrated detector of kilohertz-band gravitational radiation has been built which has sufficiently improved sensitivity over Weber's apparatus to allow comparison with his two-detector coincidenceExpand
Determining the Hubble constant from gravitational wave observations
I report here how gravitational wave observations can be used to determine the Hubble constant, H0. The nearly monochromatic gravitational waves emitted by the decaying orbit of an ultra–compact,Expand
Limits to the measurement of displacement in an interferometric gravitational radiation detector
Detection of gravitational radiation by some form of Michelson interferometer illuminated by a laser depends on observing the small relative displacements or forces which would be induced in testExpand
Gravitational-wave astronomy
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:Expand
A 30-m laser interferometer has been used in a search for gravitational radiation from the Crab pulsar. The minimum detectable signal would be produced by an incident gravitational flux of ${10}^{9}$Expand
Detection and Generation of Gravitational Waves
Methods are proposed for measurement of the Riemann tensor and detection of gravitational waves. These make use of the fact that relative motion of mass points, or strains in a crystal, can beExpand
Two-detector-coincidence search for bursts of gravitational radiation
We have made a high-sensitivity search with two calibrated detectors in coincidence for bursts of gravitational radiation at 710 Hz of duration <0.1 sec. We find less than one event per day at a fluxExpand
Noise behavior of the Garching 30-meter prototype gravitational-wave detector.
The prototype gravitational-wave detector at Garching is described: in a laser-illuminated Michelson interferometer having arms 30 m in length, a folded optical path of 3 km is realized. The origin,Expand
