Improving Gravitational Wave Detection: Interstellar Scattering Correction

Pulsar timing arrays are sensitive to Gravitational Waves (GWs). To achieve a detection of GWs, time-variable scattering observables within the dynamic Interstellar Medium must be corrected for to decrease susceptibility to highly noisy timing residuals. A semi-classical ray optics simulation with phase-tagging capabilities, as opposed to a traditional KDI, can be used to guide the mitigation strategy and understand what interstellar effects appear in both the dynamic and secondary spectra generated in our observations.
