Alternative LISA-TAIJI networks: polarization separation of the stochastic gravitational wave background

Gang Wang, Lang Liu

Stochastic gravitational-wave backgrounds (SGWBs) provide a unique opportunity to probe both unresolved astrophysical populations and fundamental physics in the early Universe. Fut…

Scalar-induced gravitational waves from a box-shaped curvature power spectrum

Zu-Cheng Chen, Lang Liu

We compute the stochastic background of gravitational waves (GWs) produced at second order in cosmological perturbation theory by a primordial curvature power spectrum that is flat…
