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…
Large anisotropies in the gravitational wave background from baryogenesis
Yan-Heng Yu, Sai Wang
Affleck-Dine (AD) baryogenesis can produce the baryon asymmetry of the Universe through the -violating dynamics of AD field. The field generally fragments into Q-balls, whose r…
Isotropic background and anisotropies of gravitational waves induced by cosmological soliton isocurvature perturbations
Di Luo, Yan-Heng Yu, Jun-Peng Li +1
Cosmological solitons are widely predicted by scenarios of the early Universe. In this work, we investigate the isotropic background and anisotropies of gravitational waves (GWs) i…
Silk Damping in Scalar-Induced Gravitational Waves: A Novel Probe for New Physics
Yan-Heng Yu, Sai Wang
Silk damping is well known in the study of cosmic microwave background (CMB) and accounts for suppression of the angular power spectrum of CMB on large angular multipoles. In this…
Anisotropies in Scalar-Induced Gravitational-Wave Background from Inflaton-Curvaton Mixed Scenario with Sound Speed Resonance
Yan-Heng Yu, Sai Wang
We propose a new model to generate large anisotropies in the scalar-induced gravitational wave (SIGW) background via sound speed resonance in the inflaton-curvaton mixed scenario.…
