The hyper luminous X-ray source ESO 243-49 HLX-1, which reaches a luminosity of 10^42 erg/s (0.2-10 keV), currently provides the strongest evidence for the existence of intermediate mass black holes. The value of the maximum X-ray luminosity is secured by the recent measurement of its distance (95 Mpc) through spectroscopic observations of its optical counterpart.
The ongoing monitoring campaign with Swift, which now covers one and a half year, has shown that HLX-1 seems to undergo spectral state transitions reminiscent of stellar mass black hole binaries, with large-scale flux variability by a factor of 100 over timescales of weeks to months. Based on XMM-Newton and Chandra dedicated pointings, including triggered observations at low and high luminosity, we bring further evidence for spectral state changes between the high/soft and low/hard states. We also present a timing analysis of the available X-ray data, and compare the results with other ULXs, low mass active galactic nuclei and Galactic stellar mass black hole X-ray binaries.
