Mounting evidence suggests that the semi-classical description of a black hole breaks down at the latest after losing an O(1) fraction of its mass. As a result, effects such as memory burden can slow down evaporation so that small primordial black holes (PBHs), in particular those in the mass range 10^6 g to 10^9 g, become viable dark matter candidates. In this paper, we investigate the production of PBHs from a prototype model of polynomial inflation with a non-minimal coupling to gravity. We show that a sufficiently small PBH mass alleviates any tension with CMB observations. Moreover, we develop efficient numerical procedures to identify model parameters and evolve Mukhanov-Sasaki modes to place bounds on the scalar-induced stochastic gravitational wave (GW) background. Whilst we identify some prospects for observation with future GW detectors, our results highlight the need to develop new experiments for high-frequency GW detection in the ~kHz to ~MHz range. Finally, we demonstrate that previously-used ans\"atze for modelling the power spectrum only yield a reliable approximation for the GW signal if some input from inflation is used.

  1. Black Hole Memory Burden and its Signatures in Gravitational Waves from Mergers

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Swift memory burden shifts black-hole quasinormal-mode frequencies by an amount set by the memory-load parameter μ and critical exponent p, with μ able to exceed the progenitor's information content.

  2. Detecting dark objects in the Solar System with Gravitational Wave observatories

    gr-qc 2025-07 conditional novelty 6.0 of 10

    DECIGO could detect compact dark matter objects with masses 10^7 to 10^11 g flying through the solar system via their gravitational perturbation of the detector test masses.

  3. Tensor induced gravitational waves

    astro-ph.CO 2025-07 conditional novelty 4.0 of 10

    Second-order tensor-induced gravitational waves can shift the inferred parameters of small-scale primordial gravitational wave models fitted to NANOGrav 15-year data, with one model favored by Bayes factors.

  4. Relativistic accretion and burdened primordial black holes

    astro-ph.CO 2025-07 conditional novelty 4.0 of 10

    Combining relativistic accretion with memory-burdened evaporation widens the parameter space for primordial black holes as dark matter and changes dark matter and dark radiation emission predictions.

  5. New bounds on Memory Burdened Primordial Black Holes from Big Bang Nucleosynthesis

    astro-ph.CO 2025-06 reject novelty 4.0 of 10

    Memory-burdened primordial black holes lighter than 10^9 grams are newly constrained by Big Bang nucleosynthesis, with a residual unconstrained window around 1-100 grams for suppression index k=2.
