The detection of gravitational waves from mergers of tens of Solar mass black hole binaries has led to a surge in interest in Primordial Black Holes (PBHs) as a dark matter candidate. We aim to provide a (relatively) concise overview of the status of PBHs as a dark matter candidate, circa Summer 2020. First we review the formation of PBHs in the early Universe, focusing mainly on PBHs formed via the collapse of large density perturbations generated by inflation. Then we review the various…

The hand-made tail: non-perturbative tails from multifield inflation
Abstract It is becoming increasingly clear that large but rare fluctuations of the primordial curvature field, controlled by the tail of its probability distribution, could have dramatic effects on

These lecture notes are based on those presented at the Theoretical Aspects of Astroparticle Physics, Cosmology and Gravitation School at the Galileo Galilee Institute in Florence in 2021. They aim
Limits on primordial black holes from M87
Primordial black holes in the solar mass range are a possibly significant component of dark matter. We show how an argument relating the deflection of light by such black holes in the density spike
Primordial black hole formation with full numerical relativity
We study the formation of black holes from subhorizon and superhorizon perturbations in a matter dominated universe with 3+1D numerical relativity simulations. We find that there are two primary
TeV Dark Matter searches in the extragalactic gamma-ray sky
: High-energetic gamma rays from astrophysical targets constitute a unique probe for annihilation or decay of heavy particle Dark Matter (DM). After several decades, diverse null detections have

Primordial black holes from valley
Primordial black holes (PBHs) could be formed if large perturbations are generated on small scales in inflation. We study a toy inflation model with a local minimum. The curvature perturbations are
Measuring dark matter spikes around primordial black holes with Einstein Telescope and Cosmic Explorer
Future ground-based gravitational wave observatories will be ideal probes of the environments surrounding black holes with masses 1 − 10 M (cid:12) . Binary black hole mergers with mass ratios of

Dark matter is likely to be the main component of the universe, but it doesn’t belong to any part of known substances, which make up the visible celestial bodies. Although dark matter has not been
Diffuse emission from black hole remnants
We point out that conservation of information implies that remnants produced at the end of black hole evaporation should radiate in the low-frequency spectrum. We model this emission and derive
