论文摘要
先进的Ligo/处女座干涉仪已观察到$ \ sim 100 $引力波瞬变，从而可以回答有关相对论，天体物理学和宇宙学的新问题。但是，随着未来瞬态目录的增加，我们当前的许多计算这些限制程序的扩展都无法很好地扩展。我们引入了一种新型的混合采样方法，以便使用重力波信号进行更有效的一般相对性参数化测试。将我们的方法应用于二进制黑洞合并GW150914并模拟信号，我们发现我们的方法大约比当前的方法比当前的方法更有效，并具有保守的设置，以进行混合分析。尽管我们专注于衡量潜在偏差与相对论的特定问题，但我们的方法对任何可以分解为简单，更复杂的模型的问题都非常适用。
The Advanced LIGO/Virgo interferometers have observed $\sim 100$ gravitational-wave transients enabling new questions to be answered about relativity, astrophysics, and cosmology. However, many of our current procedures for computing these constraints will not scale well with the increased size of future transient catalogs. We introduce a novel hybrid sampling method in order to more efficiently perform parameterized tests of general relativity with gravitational-wave signals. Applying our method to the binary black hole merger GW150914 and simulated signals we find that our method is approximately an order of magnitude more efficient than the current method with conservative settings for our hybrid analysis. While we have focused on the specific problem of measuring potential deviations from relativity, our method is of much wider applicability to any problem that can be decomposed into a simple and more complex model(s).
