    Theoretical models and observations suggest that primordial Stellar Black Holes
    (Pop-III-BHs) were prolifically formed in HMXBs, which are powerful relativistic jet sources of synchrotron radiation called Microquasars (MQs).

    Large populations of BH-HMXB-MQs at cosmic dawn produce a smooth synchrotron cos-
    mic radio background (CRB) that could account for the excess amplitude of atomic...

    In two recent papers (Zdziarski et al. 2017, 2018), we presented measurements by the Fermi/LAT and theoretical interpretation of the gamma-ray spectra from two Galactic microquasars, Cyg X-1 and Cyg X-3. In both sources, orbital modulation (due to Compton anisotropy of scattered stellar photons from the donor) has been measured, which has allowed us to estimate of the location of the bulk of...
