修正引力中的错位自旋黑洞合并(MOG)
Misaligned Spin Merging Black Holes in Modified Gravity (MOG)
摘要:
合并黑洞的一个有希望的特征是它们的自旋角分布。我们考虑的alIGO合作引力波测量的二元黑洞自旋和预测的修正重力(MOG)的合并黑洞的不对齐的自旋的偏好。在MOG中,两个黑洞合并过程中引力的增强降低了有效自旋参数$χ_{\rm eff}\sim 0$,这与aLIGO合作组在引力波探测中观测到的合并黑洞的自旋失准一致。
英文摘要:
A promising signature of coalescing black holes is their spin angular distribution. We consider the aLIGO collaboration gravitational wave measurements of the binary black hole spins and the predicted modified gravity (MOG) preference for misaligned spins of the coalescing black holes. In MOG, during the merger of two black holes, the enhanced strength of gravitation reduces the effective spin parameter $χ_{\rm eff}\sim 0$ in agreement with the measured spin misalignment of the merging black holes observed in the gravitational wave detections by the aLIGO collaboration.
