The research I performed was an attempt to generate a mathematical model to find the amount of scattering present in the intergalactic medium (IGM) and the scattering angles associated with fast radio bursts (FRB’s). This research was prompted by a report (Thornton et al, 2013) of millisecond radio bursts emanating from cosmological distances. Working with Professor Brian Dennison, we were able to generate several equations which incorporate Minkowski’s general relativity in spherical coordinates, the expansion of the universe with contributions from both luminous and dark matter to try and quantify the FRB phenomenon. These equations were entered into a piece of mathematical software, Mathematica, to evaluate the complex integrals that were generated. The data set produced could eventually be useful to radio astronomers when dealing with observations of FRB’s. This idea is very complicated, and this project naturally leads to further work. But through our efforts, a big step has been toward understanding the FRB phenomenon more fully.
