|Title||Multiwavelength Test For A Standard Accretion Disk Around An Intermediate BHC|
|Author||Dr Hua Feng|
|Description||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.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
