Historically the most popular dark matter candidates have been new elementary particles, such as Weakly Interacting Massive Particles and axions. However Primordial Black Holes (PBHs), black holes formed from overdensities in the early Universe, are another possibility. The discovery of gravitational waves from mergers of tens of Solar mass black hole binaries by LIGO-Virgo has generated a surge in interest in PBH dark matter. We overview the formation of PBHs, observational probes of their abundance, and some of the key open questions in the field.

  5. Memory burden effect of regular primordial black holes

    astro-ph.CO 2026-05 unverdicted novelty 5.0 of 10

    Combining regular black hole metrics with memory burden suppresses evaporation and opens a 10^6-10^8 g PBH mass window that can comprise all dark matter.

  6. SWIM: Stochastic Warm Inflation Module to generate and analyse Warm Inflationary power spectrum

    astro-ph.CO 2026-04 unverdicted novelty 5.0 of 10

    SWIM is a publicly available numerical platform that generates full Warm Inflation scalar power spectra and enables MCMC parameter estimation with CMB data for arbitrary potentials and dissipation forms.

  7. Impact of facility timing and coordination for next-generation gravitational-wave detectors

    gr-qc 2025-10 unverdicted novelty 5.0 of 10

    Simulations of ET and CE networks show delays degrade localization metrics far more than SNR, with LIGO India greatly reducing the impact for multi-messenger and stochastic searches.
