gravitational wavesLIGO on SeptemberculminationThe first observation of gravitational waves, by LIGO on September 14, 2015, was the culmination of a near half century effort by 1200 scientists and engineers of the LIGO/Virgo Collaboration. It was also the remarkable beginning of a whole new way ...
LIGO physicists may have been fooled into thinking they were picking up gravitational waves when they weren't. Perhaps there was something up with the detectors that meant they produced gravitational wave signals where none existed. The Copenhagen paper was met by a swift rebuke from Ian Harry,...

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...
We discuss the statistical challenges presented by data from large-scale gravitational-wave interferometers now under construction. Extracting information from signals requires measuring parameters, and sophisticated algorithms may be required to attain maximal possible accuracy. Detecting continuous waves from ...
On September 14, 2015, the two LIGO detectors operating at Hanford, WA and Livingston, LA nearly simultaneously recorded a strong trigger consistent with the passage of gravitational waves. An extensive and thorough analysis by the LIGO ... D Brown - American Physical Society 被引量: 1487发表:...

作者: LIGO Scientific Collaboration 摘要: We perform a wide parameter-space search for continuous gravitational waves over the whole sky and over a large range of values of the frequency and the first spin-down parameter. Our search method is based on the Hough transform, which is a semi...
