报告摘要：Thanks to the development of numerical relativity and the nice idea of the effective one body reduction of two body problems, the effective-one-body formalism has been developed to describe the full inspiral-merger-ringdown gravitational wave form generated by binary black hole. The effective-one-body formalism can be used to describe the wave form for generic binary black hole systems including generic mass ratio and spin cases and even precession cases. Despite these great successes of the effective-one-body formalism, the nonlinear gravitational-wave memory part is missing in this formalism. And this missing is essential. There is no consideration of memory at all in the effective-one-body formalism currently. Here we give deep insight to the nonlinear memory within the effective-one-body formalism. Based on these understandings we propose a phenomenological model for the nonlinear gravitational-wave memory for the full inspiral-merger-ringdown process of binary black hole systems. Together with this memory model, the effective-one-body formalism will be complete for binary black hole gravitational wave-form description.
