Gravitation Wave and Gravitational-wave Sources
摘要
Abstract
The recent discovery of gravitational-wave burst GW150914 marks the coming of a new era of gravitational-wave astronomy, which provides a new window to study the physics in the strong gravitational fields, the extremely massive stars, extremely high energy processes and extremely early Universe. In this article, we introduce the basic characters of gravitational wave in Einstein's general relativity, their observational effects and main gener-ation mechanisms, including the rotation of neutron stars, the evolution of binary systems, the spontaneous generation in the inflation universe. Different sources produce the gravita-tional waves at quite different frequencies, which can be detected by different methods. In the lowest frequency range (f < 10-15 Hz), the detection is mainly dependent of the observation of B-mode polarization of cosmic microwave background radiation. In the middle frequency range (10-9 < f < 10-6 Hz), one detects gravitational waves by analyzing the timing resid-uals of millisecond second pulsars. In the high frequency range (10-4 < f < 104 Hz), it can be detected by space-based and ground-based laser interferometers. In particular, we focus on the main features, detection methods, detection status and the future prospects for sev-eral important sources, including the continuous sources (e.g. spinning neutron stars, stable binary systems), the burst sources (e.g. supernovae, the mergence of binary system), and the stochastic backgrounds generated by the astrophysical and cosmological process. In addition, we forecast the potential breakthrough processes in gravitational-wave astronomy in the near future, and the Chinese projects which might involve in these discoveries.关键词
