AbstractLIGO opens a new window to look further into the universe by hearing the chirp of gravitational waves(GWs). We provide a concise introduction of GW solution of the linearized field equation of general relativity(GR), the quadrupole radiation formula, the strength estimate of GWs, and the inspiral-merge-ringdown waveforms of binary black holes simulated by numerical relativity. Finally we present an outline of GW astronomy and cosmology by reciting the predictions and conjectures proposed by Kip Thorne concerning GWs and the related subjects.
Other Abstract激光干涉引力波天文台(LIGO)的引力波观测打开了认识宇宙的新窗口。文章从引力场方程的线性化开始,介绍了引力波的弱场近似解、四极辐射、波源和频率以及黑洞结合的模拟波形。最后借Kip Thorne关于引力波的预言和猜想,呈现引力波宇宙学的前景。
