Gravitational Waves from Hyperbolic Encounters of Primordial Black Holes in Dwarf Galaxies
Tadeo D. Gòmez-Aguilar, Encieh Erfani, N. M. Jimènez Cruz
We investigate the stochastic gravitational wave background (SGWB) generated by primordial black holes (PBHs) in the dense cores of dwarf galaxies (DGs), considering both hierarchi…

Clustering of Primordial Black Holes in Excursion Set Theory
Hamed Kameli, Encieh Erfani
We investigate the clustering of Primordial Black Holes (PBHs) within the framework of Excursion Set Theory (EST). The EST formalism is extended to compute the joint probability of…

Constraints on primordial black holes for nonstandard cosmologies
Tadeo D. Gomez-Aguilar, Luis E. Padilla, Encieh Erfani +1
We study how the bounds on the abundance of Primordial Black Holes (PBHs) and the constraints on power spectrum are modified if a non-standard evolution phase takes place between t…
