Description | We are proposing XMM observations of a small sample of Ultraluminous X-ray sources (ULXs)which have high enough XMM counting rates to enable sensitive searches for mHz QPOs and broadband power spectral features. Recent detection of QPOs in a ULX in M82 demonstrates that timing studies can provide a powerful new tool to probe the properties of ULXs. Some of the primary goals of our study include: 1) Search for mHz QPOs. 2) Obtain broad band power spectra to determine the typical rms variability levels with photon energy and 3) To make detailed comparisons with the timing properties of Galactic black hole systems of known 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. |
