Using gravitational waves to see the first second of the Universe
Gravitational waves are a unique probe of the early Universe, as the Universe is transparent to gravitational radiation right back to the end of inflation. This review summarizes detection prospects and the wide scope of primordial events that could lead to a detectable stochastic gravitational wave background. Any such background would shed light on what lies beyond the standard model, sometimes at remarkably high scales. The range of strategies for detecting a stochastic gravitational wave background is overviewed before the review delves into three major primordial events that can source such a background. Finally, the landscape of other sources of primordial backgrounds is summarized.

Abstract
Gravitational waves are a unique probe of the early Universe, as the Universe is transparent to gravitational radiation right back to the end of inflation. This review summarizes detection prospects and the wide scope of primordial events that could lead to a detectable stochastic gravitational wave background. Any such background would shed light on what lies beyond the standard model, sometimes at remarkably high scales. The range of strategies for detecting a stochastic gravitational wave background is overviewed before the review delves into three major primordial events that can source such a background. Finally, the landscape of other sources of primordial backgrounds is summarized.
