Abstract: | 我們使用 Pablo A. Rosado 的方法來計算來自雙星系統與旋轉中子星的重力波背景的譜函數,並且使用最近得到的模型與宇宙參數。Rosado 的重疊函數能夠顯示出重力波背景的可解析性與連續性。將我們計算出的不可解析背景和連續背景與觀測實驗的遺棄的靈敏度曲線做比較,我們可以得知該觀測實驗能探測到何種目標的重力波,以及是否會受到不可解析訊號的汙染。從我們的結果可以得知地面探測器不會受到來自雙星系統與旋轉中子星的不可解析背景的干擾。 We calculated the gravitational wave background from binary systems and rotating neutron stars using Pablo A. Rosado’s recipes of calculating spectral functions with the latest models and cosmological parameters. The overlap functions in Rosado’s works can characterize the resolvability and continuity of the background. Compare the predicted unresolvable and continuous gravitational wave backgrounds to the sensitivity curves of gravitational wave detectors, we can know from which target the background can be detected by the current and planned detectors, and whether the detector would be contaminate by the unresolvable signals. Our results show that the ground-based detectors are free from the unresolvable backgrounds both from binary systems and rotating neutron stars. |
