Reverse Engineering the Mass of the Heaviest Black Hole Merger Discovered

On May 21, 2019 Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521. A curious aspect of its mass is that it cannot be explained by the usual means we expect black holes to form: stellar core collapse. This would imply that GW190521 is a product of generations of mergers, and thus it is the purpose of this research to deduce those generations. Our current approximation of the physics of these mergers occurs in 4 dimensions: two for mass and two for spin. This presents the issue of creating a parameter space in 4 dimensions, along with the need for simulations across hundreds of thousands of masses and spins. This project will be completed using LIGO data, GW-OSC’s parameter estimation, and NRSUR7dq4, an inspiral-merger-ringdown waveform model.
