A standard expectation of primordial cosmological inflation is that it dilutes all relics created before its onset to unobservable levels. We present a counterexample to this expectation by demonstrating that a network of cosmic strings diluted by inflation can regrow to a level that is potentially observable today in gravitational waves (GWs). In contrast to undiluted cosmic strings, whose primary GW signals are typically in the form of a stochastic GW background, the leading signal from a diluted cosmic string network can be distinctive bursts of GWs within the sensitivity reach of current and future GW observatories.

引力波爆炸是通货膨胀稀释的宇宙弦的预兆

对原始宇宙学通货膨胀的标准期望是，它将原始发病前产生的所有文物稀释到无法观测的水平。我们通过证明由通货膨胀稀释的宇宙弦网络可以重新发展到今天在重力波（GWs）中可能观察到的水平，来反驳这一期望。与未稀释的宇宙弦相比，其主要GW信号通常以随机GW背景的形式出现，而来自稀释的宇宙弦网络的主导信号可能是当前和未来GW观测站灵敏度范围内的GW爆发。
