    An extremely powerful long-lived superluminal ejection from the black hole MAXI J1820+070

    Black holes in binary systems execute patterns of outburst activity where two characteristic X-ray states are associated with different behaviours observed at radio wavelengths. The hard state is associated wi...

    An elevation of 0.1 light-seconds for the optical jet base in an accreting Galactic black hole system

    Relativistic plasma jets are observed in many systems that host accreting black holes. According to theory, coiled magnetic fields close to the black hole accelerate and collimate the plasma, leading to a jet ...

    Finding Faint Intermediate-Mass Black Holes in the Radio Band

    We discuss the prospects for detecting faint intermediate-mass black holes, such as those predicted to exist in the cores of globular clusters and dwarf spheroidal galaxies. We briefly summarize the difficulti...

    ASOCAM Observations of CYG X-3: Search for a Hot Stellar Wind

    Six CAM observations have been made in the 4 - 14 µm wavelength region to search for further evidence of emission from a hot stellar wind. Initial results suggest that the spectrum detected by Fender et al. us...
