Evading the CMB -distortion bound on Supermassive Primordial Black Hole seeds with Non-Gaussian tails
Sanket Dave, Sheng-Feng Yan, Amara Ilyas +1
The paper studies how non‑Gaussian tails in the primordial curvature perturbation can enable the formation of supermassive primordial black hole seeds (10^5–10^7 M☉) while staying…

Primordial Black Hole Formation in Dust-Radiation Bouncing Cosmologies
Xuan Ye, Luiz Felipe Demetrio, Eduardo Jose Barroso +2
Primordial black holes (PBHs) provide a unique probe of the early Universe and may have an enhanced abundance in bouncing cosmologies, where a long contracting phase can amplify pe…
