Characterization of a Potential Systematic Error in aLIGO

In this project, I identify a potential systematic error in the advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO). A potential molecular influencer for light sources in interferometry is identified and its effects are predicted. This is accomplished through the modeling of redshift as a function of the distance and density of the medium. The result implies both a loss of energy and velocity during the propagation of the light sources in aLIGO.
