Millicharged particles weaken pulsational pair-instability in massive stars, shifting the lower edge of the black hole mass gap upward and turning gravitational wave observations into a probe for particles with masses 35-200 keV and charges 10^{-10} to 10^{-9}.

Semi-analytical fits are derived for millicharged particle energy-loss rates in three regimes relevant to pre-supernova stellar cores.
Dark photon solitons emit photons through external-field dipole radiation and kinetic mixing, offering a novel astrophysical signature for wave-like dark matter.

The Black Hole Mass Gap as a New Probe of Millicharged Particles
Millicharged particles weaken pulsational pair-instability in massive stars, shifting the lower edge of the black hole mass gap upward and turning gravitational wave observations into a probe for particles with masses 35-200 keV and charges 10^{-10} to 10^{-9}.
