Black Holes in the Early Universe
Bernard Carr,Stephen W. Hawking +1 more
TL;DR: The existence of galaxies indicates that the early universe must have been inhomogeneous and might have been highly chaotic as discussed by the authors, which could have lead to regions of the size of the particle horizon undergoing gravitational collapse to produce black holes with initial masses from 10-5 g upwards.
Journal ArticleDOI
The Primordial black hole mass spectrum
TL;DR: The mass spectrum of primordial black holes should result if the early universe consisted of small density fluctuations superposed on a Friedmann background as mentioned in this paper, and it is shown that only a certain type of fluctuation favors the formation of black holes and that their spectrum should always have a particular form.
Journal ArticleDOI
New cosmological constraints on primordial black holes
Bernard Carr,Bernard Carr,Bernard Carr,Kazunori Kohri,Kazunori Kohri,Kazunori Kohri,Yuuiti Sendouda,Yuuiti Sendouda,Jun'ichi Yokoyama,Jun'ichi Yokoyama +9 more
TL;DR: In this article, the fraction of the universe going into primordial black holes in the mass range was studied and the effects of their evaporations on big bang nucleosynthesis and the extragalactic photon background were discussed.
Journal ArticleDOI
Primordial Black Holes as Dark Matter
TL;DR: The possibility that the dark matter comprises primordial black holes (PBHs) is considered in this paper, with particular emphasis on the currently allowed mass windows at 10(16)-10(17) g, 10(20)-10 (24) g and 1-...
Journal ArticleDOI
Primordial Black Holes as Dark Matter: Recent Developments
Bernard Carr,Florian Kuhnel +1 more
TL;DR: Although the dark matter is usually assumed to be made up of some form of elementary particle, primordial black holes (PBHs) could also provide some of it as mentioned in this paper.
