[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 …

Seven hints that early-time new physics alone is not sufficient to solve the Hubble tension
S Vagnozzi - Universe, 2023 - mdpi.com
The Hubble tension has now grown to a level of significance which can no longer be
ignored and calls for a solution which, despite a huge number of attempts, has so far eluded …
