报告摘要:
The recently released data by pulsar timing array (PTA) collaborations present strong evidence for a stochastic signal consistent with a gravitational-wave background. In this talk, I will disscuss some implications for scalar-induced gravitational waves with pulsar timing arrays, including the non-Gaussianity of curvature perturbation, equation of state of the early Universe, and sound speed resonance.
