Analytical relativity and the first direct detections of gravitational waves

prof. dr hab. Piotr Jaranowski


After a short update on the first direct detections of gravitational waves being made by LIGO detectors, the crucial role of analytical relativity results for the successful detections and estimation of parameters of gravitational-wave signals coming from coalescing black-hole binaries will be explained. The adjective "analytical" means here methods that rely on solving explicit (that is analytically given) ordinary differential equations, contrary to full numerical relativity simulations. Among numerous analytical relativity results the emphasis will be placed on post-Newtonian approximations and on effective one-⁠body approach to relativistic two-body problem.
