Waveform templates and signal recognition for extreme and intermediate mass-ratio inspirals
Abstract
Extreme and intermediate mass-ratio inspirals are important gravitational wave sources for space-borne detectors, and they are important tools for testing the theory of gravity under strong field conditions, measuring the nature of black holes, studying the dynamics of galaxies, and other important scientific issues. The gravitational wave signals generated by such sources often have durations of several years, are very weak and have complex compositions. In order to successfully detect extreme and intermediate mass-ratio inspirals, it is particularly important to construct accurate and efficient waveform templates and signal identification techniques. In this paper, we will first review the techniques of waveform computation, methods and advances in template construction, and then discuss the development and current status of signal recognition techniques.
