Primordial black holes can represent all or most of the dark matter in the window $10^{17}-10^{22}\,$g. Here we present an extension of the constraints on PBHs of masses $10^{13}-10^{18}\,$g arising from the isotropic diffuse gamma ray background. Primordial black holes evaporate by emitting Hawking radiation that should not exceed the observed background. Generalizing from monochromatic distributions of Schwarzschild black holes to extended mass functions of Kerr rotating black holes, we show that the lower part of this mass window can be closed for near-extremal black holes.

  1. Constraints on Primordial Black Holes from Galactic Diffuse Synchrotron Emissions

    hep-ph 2026-01 conditional novelty 5.0

    Galactic synchrotron emissions above 20 MHz can set tighter upper limits on the abundance of primordial black holes with masses above 10^16 grams than previous cosmic-ray electron data.

  2. Limits on primordial black holes from the extragalactic gamma-ray background; current status and future projections

    astro-ph.HE 2026-06 unverdicted novelty 4.0

    Sets upper limits on primordial black hole dark matter fraction using extragalactic gamma-ray background, claiming these are the tightest indirect constraints for the mass range.

  3. Constraints on Primordial Black Holes

    astro-ph.CO 2020-02 accept novelty 4.0

    Updated compilation shows PBHs are tightly constrained across 55 orders of magnitude in mass, ruling out dominant dark matter contributions except in narrow windows, with many limits carrying observational uncertainties.
