Propagation of gravitational waves in a universe with slowly-changing equation of state
摘要：
探讨了暗能量按简单模型演化的平坦宇宙膨胀的精确解。求解并探讨了弱原初引力波在该宇宙中的传播方程，在同时具有“大爆炸”奇点和“大撕裂”奇点的平坦宇宙学中，引力波可以用汇合Heun函数来描述.我们开发的近似方法合流Heun方程的感兴趣的制度，引力波天文学家和预测的引力波振幅在宇宙中的大爆炸和大撕裂的减少。
英文摘要：
An exact solution for the expansion of a flat universe with dark energy evolving according to a simple model is explored. The equation for weak primordial gravitational waves propagating in this universe is solved and explored; gravitational waves in a flat cosmology possessing both a "big bang" singularity and a "big rip" singularity can be described with confluent Heun functions. We develop approximation methods for confluent Heun equations in regimes of interest to gravitational wave astronomers and predict the diminution in gravitational wave amplitude in a universe with both a Big Bang and a Big Rip.
