    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. …”

    Gravity-Assist might be a Solution to Save Earth from Global Warming by Sohrab Rahvar

    Published 2023-11-01
    “…We can manipulate the orbit of asteroids in the asteroid belt by solar sailing and propulsion engines to guide them towards the Mars orbit and a gravitational scattering can put asteroids in a favorable direction to provide an energy loss scattering from the Earth. …”

    Integrated 6-DOF Orbit-Attitude Dynamical Modeling and Control Using Geometric Mechanics by Ling Jiang, Yue Wang, Shijie Xu

    Published 2017-01-01
    “…Finally, the integrated modeling and control are applied to the body-fixed hovering over an asteroid and verified by a simulation, in which absolute motions of the spacecraft and asteroid are simulated separately.…”
