Opening the gravitational wave window on the universe
The Laser Interferometer Gravitational Wave Observatory comprises two detectors located in Hanford, WA and Livingston LA. These detectors are 4 km long Fabry-Perot Michelson interferometers and the most sensitive length measuring devices in the world. They are able to sense a change equivalent to 1/1000th the diameter of a proton over their 4 km baseline. In this talk I will describe the technology development necessary to realise the LIGO detectors, and also describe the two gravitational wave signals that have been observed in the 1st observing run: GW150914 and GW151226. I will provide some insight into the astrophysics which can be gained from these "dark systems", only observable by listening to the universe.
