Constrains on the electric charges of the binary black holes with GWTC-1 events

Testing black hole's charged property is a fascinating topic in modified gravity and hole astrophysics. In the first Gravitational-Wave Transient Catalog (GWTC-1), ten binary merger events have been formally reported, these gravitational wave signals significantly enhanced our understanding of hole. this paper, we try to constrain amount electric charge with parameterized post-Einsteinian framework by treating as small perturbation Bayesian way. We find that current limits work are consistent result Fisher information matrix method previous works. also develop waveform model considering leading order effect for inspiral.
