Advanced LIGO detectors begin first observation run
Key contributions to advanced LIGO from AEI researchers
September 18, 2015
AEI researchers have made essential contributions to the advanced LIGO gravitational-wave detectors in several key areas: custom-made high-power laser systems required for the high-precision measurements, efficient data analysis methods running on powerful computer clusters, and accurate waveform models to detect gravitational waves and extract astrophysical information. The AEI is a leading partner in the international gravitational-wave science community, and its researchers keep pushing the boundaries of science on the way to the first direct detection of gravitational waves.
This will open a new window to the otherwise invisible “dark” side of the Universe and mark the beginning of gravitational-wave astronomy. Gravitational waves are ripples in space-time that are emitted by cataclysmic cosmic events such as exploding stars, merging black holes and/or neutron stars, and rapidly rotating compact stellar remnants. These waves were predicted in 1916 by Albert Einstein as a consequence of his general theory of relativity, but have never been observed directly. At their design sensitivity, the aLIGO instruments should detect multiple gravitational-wave events each year.
