| Abstract | Measurements of galaxy cluster temperature evolution can be used for precisioncosmology. Clusters have a wide range of temperatures, so characterizing theevolution requires determining the temperature function (TF) over a range ofredshifts. There are 6 nearly independent low z TF measurements, but only 1 athigh z. We propose to obtain the second. We will compare this independentmeasurement with the existing high z TF to check for biases and systematics. Oursimulations indicate that none will be found. If so, both samples will provideconstraints on cosmological parameters that are highly complementary to thosefrom supernovae and the microwave background. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
