[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 …

Recent gravitational wave observation by pulsar timing arrays and primordial black holes: The importance of non-Gaussianities
We study whether the signal seen by pulsar timing arrays (PTAs) may originate from
gravitational waves (GWs) induced by large primordial perturbations. Such perturbations …

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 …
