abstract

Primordial black holes (PBHs) from the early Universe have been connected with the nature of dark matter and can significantly affect cosmological history. We show that coincidence dark radiation and density fluctuation gravitational wave signatures associated with evaporation of $\lesssim10^9$ g PBHs can be used to explore and obtain important hints about the formation mechanisms of spinning and non-spinning PBHs spanning orders of magnitude in mass-range, which is challenging to do otherwise.

  1. Constraining the inflaton potential with gravitational waves from oscillons

    astro-ph.CO 2026-01 conditional novelty 6.0 of 10

    The rapid decay of an oscillon-dominated post-inflation phase produces induced gravitational waves strong enough that the BBN/CMB bound on relativistic species excludes significant regions of inflaton mass–coupling pa...

  2. Multiple Populations of Same Sterile Neutrino as Dark Matter

    hep-ph 2025-07 conditional novelty 6.0 of 10

    A single sterile neutrino species can be produced by multiple early-universe mechanisms, yielding cold and warm dark matter populations with a two-humped momentum spectrum.

  3. 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.
