Noise Reduction in the Low-Frequency LIGO Detectors

The U.S. National Science Foundation Laser Interferometer Gravitational-Wave Observatory (NSF LIGO) was the first to detect gravitational waves, back in 2015. By increasing the sensitivity in the detectors, scientists can observe more gravitational waves, and of various types; however, increasing the sensitivity also makes the equipment more susceptible to detecting external noise, which interferes with the results. For that reason, the objective of this research project is to reduce the noise i
