- Prior to the detection of GW170104 the Advanced LIGO detectors were significantly upgraded. Mow-Lowry spent several months on-site directly working on accurately measuring and improving the performance of LIGO's vibration isolation systems at low frequencies. In particular, he improved the integration of the novel Beam Rotation Sensor devices and redesigned the feed-forward system that applies that information to the observatory. These improvements substantially reduced the noise at low frequencies and led to significant improvements in operational time and stability of the observatory, hence contributing significantly to discoveries such as GW170104.
