我们利用宇宙弦上的小尺度结构模型进一步发展了Siemens、Olum和Vilenkin的结果,即宇宙弦上的引力辐射长度尺度小于先前假设的{gamma}G{mu}t。我们讨论了宇宙弦环在这个截止尺度下的一些特性,我们认为最近的网络模拟指向了两个宇宙弦环种群,一个靠近视界尺度,一个靠近引力辐射截止尺度。
We use our model of the small scale structure on cosmic strings to develop further the result of Siemens, Olum, and Vilenkin that the gravitational radiation length scale on cosmic strings is smaller than the previously assumed {gamma}G{mu}t. We discuss some of the properties of cosmic string loops at this cutoff scale, and we argue that recent network simulations point to two populations of cosmic string loops, one near the horizon scale and one near the gravitational radiation cutoff.
