Description | We propose the continuation of our XMM survey of galaxy clusters at z<0.075 located within a 40x40 sq.deg. region around the approximate location of the Great Attractor (GA) behind the Milky Way, to explain the observed large-scale flow toward and beyond the GA. All but one of our target clusters are new discoveries, found in the course of the CIZA X-ray cluster survey. Our total sample of 16 represents a complete census of the most X-ray luminous and thus presumably most massive clusters in this region. The proposed observations will allow us to measure accurate cluster masses, which in turn will permit a reconstruction of the local gravitational field that is independent of and complementary to the one based on the density of IRAS-selected field galaxies. |

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. |
