Universal Suppression of Gravitational Waves from Black Hole Evaporation Dynamics
Xin-Chen He, Xiao-Han Ma, Misao Sasaki +1
Evaporating black holes can leave distinct imprints on gravitational wave (GW) backgrounds. We show that black hole populations with finite width mass distributions exhibit a unive…

Gravitational waves from primordial black hole isocurvature: the effect of non-Gaussianities
Xin-Chen He, Yi-Fu Cai, Xiao-Han Ma +3
Ultra-light primordial black holes (PBHs) with masses can dominate transiently the energy budget of the Universe and reheat the Universe throug…
