Abstract:

Gravitational wave detectors are extremely sensitive instruments, as gravitational waves provide very subtle effects. Due to this sensitivity, the detectors
are very sensitive to environmental noise, including magnetic noise. This thesis investigates the effects of magnetic field noise in the LIGO detectors, as
measured by magnetometers located close to the LIGO observatories. In this analysis, we conduct broken power law fits to the coupling (transfer function) of the magnetic field to the LIGO detector's strain channel and track the behavior of the fits over time, during the LIGO third observation run.
