About this award
This is a Grant for Research award valued at $88,054.00 from the Shared Services Center, a civilian agency, to George Mason University for a project to study the accretion and merger dynamics of supermassive black hole binaries. The research aims to model the electromagnetic transient signals associated with these events, which is crucial for the emerging field of multimessenger astronomy. This grant does not utilize a set-aside designation. George Mason University, a large public research university in Virginia, will execute the project as the prime contractor. The awardee's parent organization, The George Mason University Instructional Foundation, Inc., has also received federal contracts and grants, primarily for technical services, software support, and small business assistance programs. This research grant will advance scientific understanding of black hole mergers and their observational signatures, supporting the agency's priorities in space and astrophysics.
Description
We propose to use these tools to study how the accretion from a surrounding circumbinary disk is distributed between the members of the supermassive black hole binary as a function of the binary separation, mass-ratio, black hole spins and orbital eccentricity, and how this may change when the separation becomes small enough for relativistic effects to become important. Mass transfer from one member of the binary to the other may play an especially interesting role. We will then simulate what happens to the gas surrounding the black holes during the merger proper and the subsequent relaxation phase. We will use our post-processing machinery to predict EM spectra and light curves throughout all these phases. This project will be a guiding beacon to enable current and future observational campaigns to recognize the transient EM signals of supermassive black hole mergers, events that both emit enormous amounts of energy in GWS and strongly influence the cosmological evolution of the supermassive black hole population. Creating such a capability is crucial for the success of the new field of multimessenger astronomy.
