Suzaku observations of two ultraluminous X-ray sources in the nearby spiral galaxy IC 342
Abstract
We report a result of our Suzaku observations for two ultraluminous X-ray sources (ULX; X-1 and X-2) in IC 342 on 2010 August and 2011 March. We found a hint of hard X-ray photons (14-20 keV), and fitted the XIS and the PIN spectra simultaneously. As a result, the joint spectra can be explained by the power-law model for X-1 and the multi-color disk model for X-2. We briefly discuss the spectral states of the two ULXs comparing with those of Galactic black hole binaries.
