Comprehensive analysis of dissipative effects in the induced gravitational waves
Yan-Heng Yu, Zhe Chang, Sai Wang
Dissipation is an intrinsic property of the cosmic fluid, leading to the damping of curvature perturbations at small scales. In this paper, we comprehensively study dissipative eff…

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…
