PostNetwonian Modeling of EMRIs and IMRIs Speaker(s): Nicolas Yunes
Abstract: Gravitational wave data analysis of compact binary systems requires the use of matched filtering. This technique crosscorrelates the data stream with a certain template that characterizes the gravitational wave signal. Successful parameterestimation thus requires an accurate model of the gravitational wave template. In this talk I will describe a new fast and accurate technique to model the gravitational wave signal from extrememass ratio inspirals. Such events consisting of a neutron star or solar mass black hole spiraling into a supermassive black hole are staple sources of the Laser Interferometer Space Antenna. This new model combines the effectiveonebody formalism of postNewtonian theory and black hole perturbation theory leading to accurate waveforms both when the supermassive black hole spins and when it does not.
