无穷导数引力中的引力辐射及其与有效量子引力的联系

Gravitational radiation in Infinite Derivative Gravity and connections to Effective Quantum Gravity

James Edholm

摘要:

Hulse-Taylor双星可能是迄今为止对GR的最佳测试。我们找到了无限导数引力(IDG)的修正四极公式。我们扩展了引力波传播的反向反应公式,发现以前的有效量子引力(EQG)的一个平坦的背景,并将此计算扩展到德西特背景的EQG和IDG。我们使用新的LIGO数据对EQG进行了更严格的限制。我们还发现的IDG框架内的圆形和椭圆形轨道的二元系统发出的功率,并使用的Hulse-泰勒二进制的例子。IDG预测的功率略低于GR,这正是观察到的结果。我们还发现我们的质量尺度上的下限为$M>4.0$ keV,这是$10^6$大于以前的结果。

英文摘要:

The Hulse-Taylor binary provides possibly the best test of GR to date. We find the modified quadrupole formula for Infinite Derivative Gravity (IDG). We extend the backreaction formula for propagation of gravitational waves, found previously for Effective Quantum Gravity (EQG) for a flat background and extend this calculation to a de Sitter background for both EQG and IDG. We put tighter constraints on EQG using new LIGO data. We also find the power emitted by a binary system within the IDG framework for both circular and elliptical orbits and use the example of the Hulse-Taylor binary. IDG predicts a slightly lower power than GR, which is exactly the observed result. We also find a lower bound on our mass scale of $M>4.0$ keV, which is $10^6$ larger than the previous result.
