Primordial Black Hole Formation from the Upward Step Model: Avoiding Overproduction

Xiaoding Wang, Xiao-Han Ma, Yi-Fu Cai

We investigate the formation of primordial black holes (PBHs) in an upward step inflationary model, where nonlinearities between curvature perturbations and field fluctuations intr…

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 $M_{PBH} < 5 \times 1 0^{8} g$ can dominate transiently the energy budget of the Universe and reheat the Universe throug…

New probe of non-Gaussianities with primordial black hole induced gravitational waves

Theodoros Papanikolaou, Xin-Chen He, Xiao-Han Ma +3

We propose a new probe of primordial non-Gaussianities (NGs) through the observation of gravitational waves (GWs) induced by ultra-light ( $M_{PBH} < 1 0^{9} g$ ) primordial…
