Research Progress in Gravitational Wave Multi-Messenger Astronomy
In 2015,the Laser Interferometer Gravitational-Wave Observatory(LIGO)in the United States made the historic discovery of gravitational waves,opening a new window for humanity to study the universe.Two years later,gravitational waves and electromagnetic waves from a binary neutron star merger were detected simultaneously,marking the advent of gravitational wave multi-messenger astronomy.This paper reviews the research history,fundamental principles,and detection techniques of gravitational wave multi-messenger astronomy,with a focus on key scientific advances,such as the multi-messenger observations of the gravitational wave event GW170817.Finally,the future development directions of gravitational wave multi-messenger astronomy are explored,emphasizing the importance of next-generation observational facilities and technological methods(such as artificial intelligence)and their potential scientific contributions.
