Primordial Black Hole Abundances and Scalar Induced Gravitational Waves from Finite-Width Power Spectra in a Stiff Thermal History

Abolhassan Mohammadi, Yogesh, Cristian Joana +2

We study the formation of primordial black holes (PBHs) from large primordial perturbations that re-enter the horizon during an epoch with equation of state $\mathrm{w}\ge 1/3$. We co…
