Effect of Vacuum Energy on Evolution of Primordial Black Holes in Einstein Gravity

open access: yes, 2011
We study the evolution of primordail black holes by considering present universe is no more matter dominated rather vacuum energy dominated. We also consider the accretion of radiation, matter and vacuum energy during respective dominance period. In this

Primordial black hole reformation in the early Universe

open access: yesPhysics Letters B
Primordial black holes (PBH) can arise in a wide range of scenarios, from inflation to first-order phase transitions. Light PBHs, such as those produced during preheating, in bounce cosmologies, or at the GUT scale, could induce an early matter-dominated

Primordial Black Hole Merger Rate in f(R) Gravity

open access: yesThe Astrophysical Journal
Primordial black holes (PBHs) are known as one of the potential candidates for dark matter. They are expected to have formed due to the direct gravitational collapse of density fluctuations in the early Universe. In this regard, examining the merger rate

Primordial black hole formation via inverted bubble collapse

open access: yesJournal of High Energy Physics
We propose a novel mechanism of primordial black hole (PBH) formation through inverted bubble collapse. In this scenario, bubbles nucleate sparsely in an incomplete first-order phase transition, such that they remain isolated and do not percolate or ...
