Constraints on primordial black holes

B Carr, K Kohri, Y Sendouda… - Reports on Progress in …, 2021 - iopscience.iop.org
We update the constraints on the fraction of the Universe that may have gone into primordial
black holes (PBHs) over the mass range 10− 5 to 10 50 g. Those smaller than∼ 10 15 g …

Primordial black holes as dark matter: recent developments

B Carr, F Kühnel - Annual Review of Nuclear and Particle …, 2020 - annualreviews.org
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. However, various …

[HTML][HTML] Observational evidence for primordial black holes: A positivist perspective

BJ Carr, S Clesse, J Garcia-Bellido, MRS Hawkins… - Physics Reports, 2024 - Elsevier
We review numerous arguments for primordial black holes (PBHs) based on observational
evidence from a variety of lensing, dynamical, accretion and gravitational-wave effects. This …

Primordial black holes and their gravitational-wave signatures

E Bagui, S Clesse, V De Luca, JM Ezquiaga… - Living Reviews in …, 2025 - Springer
In the recent years, primordial black holes (PBHs) have emerged as one of the most

Primordial black holes as dark matter candidates

B Carr, F Kühnel - SciPost Physics Lecture Notes, 2022 - scipost.org
We review the formation and evaporation of primordial black holes (PBHs) and their
possible contribution to dark matter. Various constraints suggest they could only provide …

Cosmic conundra explained by thermal history and primordial black holes

B Carr, S Clesse, J García-Bellido, F Kühnel - Physics of the Dark Universe, 2021 - Elsevier
A universal mechanism may be responsible for several unresolved cosmic conundra. The
sudden drop in the pressure of relativistic matter at W±∕ Z 0 decoupling, the quark–hadron …
