LIGO - A Gravitational Wave Observatory

Open Access Open Access

Abstract

On September 14th 2015 the LIGO gravitational wave observatories detected a coincident signal from the merger of two massive black holes 1.3 billion years ago. We explore the work needed to build these interferometers, look at the history behind the discovery, and discuss the future for the new field of gravitational wave astronomy.
