Can tensor-scalar induced GWs dominate PTA observations ?
Di Wu, Jing-Zhi Zhou, Yu-Ting Kuang +3
Observational constraints on small-scale primordial gravitational waves are considerably weaker than those on large scales. We focus on scenarios with significant primordial gravit…

Probing small-scale anisotropic inflation with stochastic gravitational-wave background
Yu-Ting Kuang, Jing-Zhi Zhou, Zhe Chang +1
In June 2023, multiple pulsar timing array (PTA) collaborations provided evidence for the existence of a stochastic gravitational-wave background (SGWB). As a significant source of…
