Gravitational waves. Reproduce yourself LIGO results.

Gravitational Waves

The LIGO Scientific Collaboration recently made the first direct detection of gravitational waves and the first observation of two black holes merging

This iPyhon notebook tutorial shows you how to recreate the results, spectrograms, and sound files. It includes code and data.

Good to learn signal processing and python….
