  text: Galactic nuclei are expected to be densely populated with stellar and intermediate
    mass black holes. Exploring this population will have important consequences for
    the observation prospects of gravitational waves as well as understanding galactic
    evolution. The gas cloud G2 currently approaching Sgr A* provides an unprecedented
    opportunity to probe the black hole and neutron star population of the Galactic
    nucleus. We examine the possibility of a G2-black hole encounter and its detectability
    with current X-ray satellites, such as Chandra and NuSTAR. We find that multiple
    encounters are likely to occur close to the pericenter, which may be detectable
    upon favorable circumstances. This opportunity provides an additional, important
    science case for leading X-ray observatories to closely follow G2 on its way to
    the nucleus.
