摘要:

用电磁辐射测量黑洞自旋的两种主要方法是铁线法和连续拟合法。它们可以被自然地扩展,用于探测黑洞周围的时空几何和在强场区检验广义相对论。在过去的几年里,有一些重要的工作是使用铁线法来测试黑洞的性质。在这封信中,我们使用连续拟合的方法,我们展示了它的能力,约束周围的时空几何黑洞通过分析17 RXTE数据的X射线双星LMC X-1。

英文摘要:

The iron line and the continuum-fitting methods are currently the two leading techniques for measuring black hole spins with electromagnetic radiation. They can be naturally extended for probing the spacetime geometry around black holes and testing general relativity in the strong field regime. In the past couple of years, there has been significant work to use the iron line method to test the nature of black holes. In this Letter, we use the continuum-fitting method and we show its capability of constraining the spacetime geometry around black holes by analyzing 17 RXTE data of the X-ray binary LMC X-1.
