Primordial Black Holes
read the original abstract
In this chapter we first describe the early history of primordial black hole (PBH) research. We then discuss their possible formation mechanisms, including critical collapse from inflationary fluctuations and various types of phase transition. We next describe the numerous constraints on the number density of PBHs from various quantum and astrophysical processes. This was the main focus of research until recently but there is currently a shift of emphasis to the search for evidence for PBHs. We end by discussing this evidence, with particular emphasis on their role as dark matter candidates, sources of gravitational waves and seeds for supermassive black holes and early cosmic structures.

In-situ globular clusters in alternative dark matter Milky Way galaxies: a first approach to fuzzy and core-like dark matter theories
In-situ globular clusters in fuzzy dark matter halos exhibit three regimes based on particle mass m22, with compact systems for low m22, CDM-like for m22~7, and extended massive systems for high m22, providing a probe...

Primordial black hole in Lorentz-violating theories: Insights from Bumblebee gravity
Bumblebee gravity enhances primordial black hole abundance through three mechanisms, but the model harbors a ghost instability and a tachyonic instability that make it cosmologically unviable.

Stochastic constant-roll inflation beyond the hilltop with the spectral method
Spectral solution of the Fokker-Planck operator for hilltop constant-roll inflation shows rare crossing trajectories dominate the mean, so the median yields a coarse-grained ΔN distribution whose exponential tail flat...

Quantum Critical Collapse Abhors a Naked Singularity
One-loop quantum vacuum polarization in Einstein-scalar critical collapse generates a horizon and finite mass gap, enforcing black hole formation even under arbitrary fine-tuning.

Impact of Primordial Black Hole population on 21 cm observables at high redshift
X-ray heating from primordial black holes assumed to seed high-redshift AGNs shallows the global 21-cm absorption signal and suppresses its power amplitude at cosmic dawn, with strong dependence on the PBH mass function.

Regular black holes with gravitational self-energy as dark matter
Incorporating non-local gravitational self-energy from a T-duality-inspired model yields a regular neutral black-hole metric with extremal Planck-mass particle-black-hole solutions that are thermodynamically stable an...
