    Ultralight boson clouds around primordial black holes emit high-frequency gravitational wave transients via superradiance and binary-driven transitions, but the signals fall below current detector sensitivity at plaus...

  2. 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.
