Title X-ray TIming Observations of Ultraluminous X-ray Sources

Author Dr Tod Strohmayer
Description We are proposing observations of a small sample of ultraluminous X-ray sources (hereafter ULXs) which have high enough XMM-Newton counting rates to enable sensitive searches for mHz quasiperiodic oscillations (QPOs) and power spectral features as well as high quality time resolved spectra. The recent detections of QPOs in a ULX in M82 and of breaks in the power spectra of NGC 4559 and perhaps NGC 5408, demonstrate 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 high quality lightcurves in order to measure the power spectrum and to allow detailed comparisons with the timing properties of Galactic and extra-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.
