With the direct discovery of gravitational waves, black holes have regain interest in the recent years. In particular primordial black holes (PBHs), which originate from the very early Universe, may constitute (at least in part) dark matter. The possibility that dark matter is made of black holes is particularly appealing, and multi-messenger searches are important to probe this hypothesis. In this paper I will discuss the concept of primordial black holes, their origins, their characteristics and the current constraints. In addition I will explain that the study of black holes is of utmost interest since they may constitute portals to new physics and to quantum gravity.

  1. Fine-tuning in mixed Dark Matter models with Primordial Black Hole relics

    astro-ph.CO 2026-08 conditional novelty 6.0 of 10

    In mixed dark matter models combining Planck-mass black hole relics, Hawking-evaporated particles, and a WIMP, freeze-in, or axion component, the total abundance's fine-tuning is dominated by the primordial power spec...

  2. Hawking Radiation from non-evaporating primordial black holes cannot enable the formation of direct collapse black holes

    astro-ph.GA 2024-11 accept novelty 5.0 of 10

    Hawking radiation from non-evaporating primordial black holes cannot provide the Lyman-Werner intensity needed to form direct collapse black holes, except possibly under extreme clustering.
