The existence of large-scale extragalactic magnetic fields (EGMFs) has been a subject of some debate over the last few decades. Recent work done on the analysis of cascade photons from high energy sources like Blazars (Tashiro and Vachaspati, 2013; Chen et al., 2015; Tashiro and Vachaspati, 2015) offer an exciting possibility of definitively proving the existence of such fields. In this thesis, the existing analysis of magnetic field measurements via cascade photon correlators will be extended to the most recent repository of data from the Fermi Large Area Telescope. In addition, a new Monte-Carlo routine to account for noise from the galactic disk will be discussed. Should this routine prove to be reliable, it could potentially be a means of explaining the anomalous observation of hemispheric dependence in the current literature.
