abstract
We show that primordial (nearly) extremal black holes with a wide range of masses from the Planck scale to around $10^9$ g could be cosmologically stable and explain dark matter, given a dark electromagnetism and a heavy dark electron. For individual black holes, Hawking radiation and Schwinger discharge processes are suppressed by near-extremality and the heaviness of the dark electron, respectively. In contrast, the merger events of binary systems provide an opportunity to directly observe Hawking radiation. Because the merger products are not extremal, they rapidly evaporate and produce transient high-energy neutrino and gamma ray signals that can be observed at telescopes like IceCube and HAWC. The relationship between the near-extremal black hole and dark electron masses could also shed light on the weak gravity conjecture.

Corrections to Hawking radiation from asteroid-mass primordial black holes: analytic and numerical evaluation of the stochastic charge effect
The stochastic charge correction to Hawking e± emission, previously derived semi-classically, is shown here to arise from QED, with a net correction below 2%.

Refining primordial black hole dark matter constraints with dust heating: the role of spin and halo profile dependence
Dust-heating constraints on PBH dark matter tighten to f_PBH ≈ 10^-4 when PBH spin is included, with the strongest limits for the Isothermal halo profile and weakest for Burkert.

Quantum improved wormholes in the Dekel-Zhao dark matter halo
An ASG-modified Newton constant combined with a Dekel–Zhao dark matter halo yields traversable wormhole geometries whose shadow radius can be tuned to the EHT Sgr A* bound by choosing the ASG scale ξ/M ≈ 0.8–0.9.

ALP production from light primordial black holes: The role of superradiance
Superradiance from spinning light primordial black holes can boost moduli production by about ten orders of magnitude, and the resulting axion-like dark radiation tightens Planck-based limits on these black holes.
