    Multi-messenger probes of asteroid mass primordial black holes: Superradiance spectroscopy, Hawking radiation, and microlensing by James B. Dent, Bhaskar Dutta, Tao Xu

    Published 2025-02-01
    “…Using axion-like particles as an example, we show that line signals emerging from a superradiated axion cloud combined with black hole Hawking radiation in extragalactic and galactic halos, along with microlensing observations lead to complementary constraints on parameter space combinations including the axion-photon coupling, axion mass, black hole mass, and its dark matter fraction, fPBH. For the asteroid mass range ∼1016−1022g, where primordial black holes can provide the totality of dark matter, we demonstrate that ongoing and upcoming observations such as SXI, JWST, and AMEGO-X will be sensitive to possible line and continuum signals, respectively, providing probes of previously inaccessible regions of fPBH parameter space. …”
