Gravitational waves
Gravitational waves are quadrupolar distortions of distances between freely falling masses. They are
Hundreds (800+) of people working on technology for LIGO detectors, producing and analyzing the LIGO/GEO data.

LSC S5 run (Nov’05-Oct’07)
With a 15 Mpc average reach, we expected ~ 1 BNS coalescence every ~50 yrs We were not lucky: data analysis did not find any detections (ligo.org), although we did have a ghost!Predicted observation rates: Class.

• Mostly (but not all) robotic wide-field optical telescopes Mainly used for following up GRBs, surveying for supernovae and other optical transients "Implementation and testing of the first prompt search for electromagnetic counterparts to
Data from a 3-detector network localized the source (very roughly) near Canis Major. Practiced a system to follow up triggers with EM telescopes/satellites.
