Multiwavelength Test For A Standard Accretion Disk Around An Intermediate Mass Black Hole Candidate
Abstract
Recent X-ray and optical observations suggest that the supersoft ultraluminous X-ray source in NGC 247 is an interesting candidate for an intermediate mass black hole, based on the fact that emission from an unusually cool and luminous accretion disk can explain multiwavelength data across 3 orders of magnitudes in wavelength. If the disk interpretation is valid, the source is predicted to be UV-luminous. Thus, we propose joint HST/XMM-Newton observations of the source for a definitive test of of the disk scenario and reliable measurement of the black hole mass.
