A Black hole solution to the cosmological monopole problem

Abstract We propose a solution to the cosmological monopole problem: primordial black holes, produced in the early universe, can accrete magnetic monopoles before the relics dominate the energy density of the universe. These small black holes quickly evaporate and thereby convert most of the monopole energy density into radiation. We estimate the range of parameters for which this solution is possible: under very conservative assumptions we find that the black hole mass must be less than 10 9 g… Expand

Holes in the walls: Primordial black holes as a solution to the cosmological domain wall problem
We propose a scenario in which the cosmological domain wall and monopole problems are solved without any fine tuning of the initial conditions or parameters in the Lagrangian of an underlying filedExpand
Primordial black holes from passive density fluctuations
Abstract In this Letter, we show that if passive fluctuations are considered, primordial black holes (PBHs) can be easily produced in the framework of single-field, slow-roll inflation models. TheExpand
Gravitational wave production by Hawking radiation from rotating primordial black holes
In this paper we analyze in detail a rarely discussed question of gravity wave production from evaporating primordial black holes. These black holes emit gravitons which are, at classical level,Expand
Clustering of primordial black holes. II. Evolution of bound systems
Primordial Black Holes (PBHs) that form from the collapse of density perturbations are more clustered than the underlying density field. In a previous paper, we showed the constraints that this hasExpand

Clustering of primordial black holes: Basic results
We investigate the spatial clustering properties of primordial black holes (PBHs). With minimal assumptions, we show that PBHs created in the radiation era are highly clustered. Using the peaksExpand
Modified hoop conjecture in expanding spacetimes and primordial black hole production in FRW universe
According to a variant of the hoop conjecture, if we localize two particles within the Schwarzschild radius corresponding to their center of mass energy, then a black hole will form. Despite a largeExpand
New cosmological constraints on primordial black holes
We update the constraints on the fraction of the Universe going into primordial black holes in the mass range 10{sup 9}-10{sup 17} g associated with the effects of their evaporations on big bangExpand

Abstract Kibble mechanism drastically underestimates the production of point-like topological defects, as confirmed recently in atomic and condensed matter systems. If non-thermally produced, theyExpand


The cosmology of black hole relics.
A toy model in which black holes evaporate to leave a relic is provided, and the question of nucleation of such objects in a thermal bath of gravitons at high temperature is addressed. Expand
Near-Critical Gravitational Collapse and the Initial Mass Function of Primordial Black Holes
The recent discovery of critical phenomena arising in gravitational collapse near the threshold of black-hole formation is used to estimate the initial mass function of primordial black holes (PBHs).Expand
Sweeping away the monopole problem
We propose a new solution to the cosmological monopole problem in which domain walls sweep away the magnetic monopoles and subsequently decay. The solution does not require extensive fine tuning orExpand
