Antipodal Angular Correlations of Inflationary Stochastic Gravitational Wave Background
Zhen-Yuan Wu, Ryo Saito, Nobuyuki Sakai
The measurement of the inflationary stochastic gravitational-wave background (SGWB) is one of the main goals of future GW experiments. In direct GW experiments, an obstacle to achi…
