There has been suggestive evidence of intermediate-mass black holes (IMBHs; 10^{3−4} M⊙) existing in some globular clusters and dwarf galaxies, but IMBHs as a population still remain elusive. I will describe a study on the long-term accretion and the observational consequence of the IMBH-main sequence star tidal disruption events. We find that the event will be UV / optically bright for a decade, followed by a long decay of X-ray emission. Looking for these luminous and long-term events in globular clusters and nearby dwarf galaxies could unveil the IMBH population. I will also describe recently discovered fast, ultra-luminous X-ray bursts, and a model explaining them which involves an IMBH and a white dwarf orbiting around it on an eccentric orbit. |
