We show that if the neutralino in the minimal supersymmetric standard model is the dark matter in our galaxy, there cannot be a dark matter cusp extending to the galactic center. Conversely, if a dark matter cusp extends to the galactic center, the neutralino cannot be the dark matter in our galaxy. We obtain these results considering the synchrotron emission from neutralino annihilations around the black hole at the galactic center.

  1. Constraining Dark Photon Dark Matter with Radio Silence from Soliton Mergers around Supermassive Black Holes

    hep-ph 2025-09 conditional novelty 6.0

    Non-observation of radio bursts from soliton mergers around supermassive black holes constrains dark photon solitons to make up less than about 1% of dark matter, with future surveys reaching 0.2%.

  2. Dipole Radiation and Kinetic Mixing from Dark Photon Solitons

    hep-ph 2026-01 unverdicted novelty 5.0

    Dark photon solitons emit photons through external-field dipole radiation and kinetic mixing, offering a novel astrophysical signature for wave-like dark matter.
