Mechanisms of gravitational wave production in supernovae, gravitational wave detector status and perspectives, and the statistical methodology used to detect these transients are reviewed. While detection of gravitational waves from supernovae with Advanced LIGO is by no means guaranteed, plausible ...
LIGOconsists of a pair of facilities operating in unison – one in Hanford, Washington, the other in Livingston, Louisiana. Since gravitational waves don’t leave clues on the electromagnetic spectrum – they cannot be seen – the shared purpose of LIGO is to “listen” to the heavens for ev...
参考消息网2月23日报道全球首个可在太空中探测引力波(gravitational waves)的设施——激光干涉仪空间天线(The Laser Interferometer Space Antenna,简称LISA)近日获欧洲航天局(European Space Agency)批准,将于2025年开始建造,计划于2035年发射。由于测量精度之高,它被科研人员称为“科幻仪器”(sci-fi instrument)。

WASHINGTON, Oct. 16 (Xinhua) -- The executive director of the gravitational wave detector LIGO on Monday hailed the first detection of such a signal as well as light from the same cosmic event as opening the door to an "entirely new kind of astronomy" and said that China could play an ...
Nearly a century after Einstein first predicted the existence of gravitational waves, a global network of Earth-based gravitational wave observatories1,2,3,4 is seeking to directly detect this faint radiation using precision laser interferometry. Photon
The detection of gravitational waves by the LIGO system of interferometers in the USA proved Einstein’s prediction of the existence of gravitational waves. VAT vacuum valves help maintain the large vacuum volume of the LIGO system. (3 min. read) ...
