Gravitational wave templates and signal recognition of supermassive binary black holes

Supermassive binary black holes are among the most important and primary sources of gravitational wave detections by space-based detectors. Similar to ground-based gravitational wave detections, the matched filtering data analysis method is a standardized approach for processing gravitational wave data and measuring source parameters to get astrophysical information. The waveform template of the wave source is a prerequisite for implementing the matched filtering method. This article focuses on the problem of gravitational wave template and signal recognition for supermassive binary black holes. Based on the research results of the author's research team in recent years, a brief review is made on the construction of gravitational wave templates and the development of signal recognition methods for supermassive binary black holes. The purpose is to help readers quickly understand the current research status of gravitational wave templates and signal recognition for supermassive binary black holes in space-based gravitational wave detection.
