我们能从GW 150914中真正推断出什么？
What can we really infer from GW 150914?
摘要：
我们分析了由高级激光干涉引力波天文台（LIGO）宣布的事件GW 150914作为黑洞双星合并的引力波发射。我们表明，合并系统和新形成的克尔黑洞的参数可以提取的引力波发射的基本结果在吸气和合并阶段，没有复杂的数值模拟。我们惊人准确的估计是基于描述两种不同状态的教科书公式：1）在Landau和Lifshitz教科书中处理的二元螺旋分析，以及2）在Rees-Ruffini-Wheeler教科书中处理的粒子陷入黑洞。它强调，为了推断任何天体物理信息的质量系统的两个政权必须独立和观测约束LIGO，这似乎不是这样的。
英文摘要：
We analyze the event GW 150914 announced by the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) as the gravitational-wave emission of a black-hole binary merger. We show that the parameters of the coalescing system and of the newly formed Kerr black-hole can be extracted from basic results of the gravitational-wave emission during the inspiraling and merger phases without sophisticated numerical simulations. Our strikingly accurate estimates are based on textbook formulas describing two different regimes: 1) the binary inspiraling analysis treated in Landau and Lifshitz textbook, and 2) the plunge of a particle into a black-hole, treated in the Rees-Ruffini-Wheeler textbook. It is stressed that in order to infer any astrophysical information on the masses of the system both regimes have to be independently and observationally constrained by LIGO, which does not appear to be the case.
