Waves of the spacetime
Gravitational waves are the oscillation of space-time, propagating as a wave at the speed of light. Einstein first predicted these waves based on his own theory of gravity - The General Theory of relativity - in 1916. It took nearly 100 years before these elusive waves could be directly detected.
It was recently that two LIGO detectors in the USA first directly detected gravitational waves. The coalescing binary blackhole event GW150914 was known as three-fold discovery.

(2) Blackholes
(3) Merger of two blackholes resulting in single Kerr blackhole

Here are some of the basics of GW data analysis
Good starting point for the overall idea about GW astronomy are these three papers by
Bernard F. Schutz, all available @ arXiv
Basic Detection Theory
What comes next is brief theory of detection based on Neyman-Pearson criterion,
details about Fourier transform both continuous and discrete are given in the
paper by Bernard F. Schutz. This is an important review from data analysis point
of view.
