    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. …”

    Grand canyons on the Moon by David A. Kring, Danielle P. Kallenborn, Gareth S. Collins

    Published 2025-02-01
    “…Here we use photogeologic mapping of those canyons and related impact ejecta deposits to show the trajectory of the impacting asteroid or comet, which produced an asymmetrical pattern of crater excavation and transport of ejected debris. …”

    Retinocytoma Undergoing Retinoblastoma Transformation in an Adult Patient by J. Navaratnam, R. Faber, N. Eide, M. Lund-Iversen, Ø. Garred, F. L. Munier

    Published 2023-01-01
    “…Following brachytherapy, he had two episodes of right-sided vitreous hemorrhage that spontaneously cleared up, and the remaining finding in the vitreous cavity was interpreted as asteroid hyalosis. He underwent vitrectomy about five years following brachytherapy. …”

    JWST Near-infrared Spectroscopy of High-albedo Jupiter Trojans: A New Surface Type in the Trojan Belt by Michael E. Brown, Ian Wong, Matthew Belyakov

    Published 2025-01-01
    “…The 0.8–2.5 μ m spectra of these objects match the spectra of neither the well-known “red” and “less-red” Jupiter Trojans nor of any known asteroid taxonomic class. The reflectivity of these objects does not rise redward of 4 μ m, a property that is seen in the previous JWST observations of Jupiter Trojans only in Polymele. …”

    Chronic Inflammatory Arthropathy Preceding Acute Systemic Manifestations of Sarcoidosis: A Possible Overlap of Idiopathic Juvenile Arthritis and Sarcoidosis by Matheus Campello Vieira, Priscilla Gomes Tosta, Fernanda Morello Nicole, Lucas Enock V. Roberto, Júlia Guasti P. Vianna, Paulo de Coelho Castro, Rafael Burgomeister Lourenço, Erica Vieira Serrano, Valéria Valim, Weverton Machado Luchi

    Published 2019-01-01
    “…The initial diagnostic hypothesis was lymphoproliferative disease, but the laparoscopic propaedeutic showed multiple white lesions on the liver surface, which biopsy identified as noncaseating granulomas with asteroid corpuscles, suggestive of sarcoidosis. He was treated with corticosteroids with significant improvement in symptoms and in calcium and creatinine levels. …”
