Upgrade complete for gravitational-wave observatory

Physics World, 2015
A $200m upgrade to the Laser Interferometer Gravitational-wave Observatory (LIGO) has been completed, with the facility set for observations in the coming months as it aims to be the first to detect a gravitational wave.

UNDERGROUND GRAVITATIONAL WAVE OBSERVATORIES: KAGRA AND ET

International Journal of Modern Physics D, 2013
Future gravitational wave observatories will be realized underground in order to reduce external disturbances, such as seismic, Newtonian and environmental noises. The Japanese gravitational wave telescope KAGRA is under construction at the Kamioka site and the Einstein Telescope gravitational wave observatory is under study in Europe; the common ...

The `bar' gravitational wave observatory: results, status and prospects

Classical and Quantum Gravity, 2001
Summary: A review is given of the results of the coincidence searches recently performed under the International Gravitational Events Collaboration (IGEC) with the five cryogenic `bar' detectors in operation. The capabilities of such a gravitational wave `observatory' are discussed, in view of both the performance of current bars and the performance ...

Optical metrology for gravitational wave observatories and geophysics

Conference on Lasers and Electro-Optics, 2021
Decades of efforts by the scientific community in advancing optical metrology enable unprecedented displacement sensitivities that make our scientific endeavors possi- ble. Examples from the gravitational-wave and geodesy communities are briefly presented in this paper.

CEGO: china einstein gravitational wave observatory

2004 Asia-Pacific Radio Science Conference, 2004. Proceedings., 2005
Gravitational waves were predicted by Einstein's general relativity. Up to now there has been no direct evidence for gravitational waves. Since the 1990's, laser interferometers have become the dominant detectors for gravitational wave detection, LIGO, Virgo, GEO600 and TAMA300 are the major laser interferometer gravitational wave observatories in the ...

The Laser Interferometer Gravitational-Wave Observatory LIGO

Advances in Space Research, 2000
Abstract The Laser Interferometer Gravitational-Wave Observatory (LIGO) Project to develop a terrestrial astronomical observatory for gravitational wave detection is being developed by a Caltech-MIT collaboration. This effort is complementary to plans for detection in space, as it is sensitive to a higher frequency band (10Hz to 10kHz) and therefore ...

Techniques for Third-Generation Gravitational-Wave Observatories

Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007
Third generation detectors aim to improve the sensitivty roughly by another order of magnitude beyond the second or advanced generation. This talk presents difficulties and possible solutions that may be used to reach this goal. Article not available.
