| Description | Super-massive black holes (SMBHs) at redshift z>7 pose a serious challenge to our understanding of black hole (BH) formation and evolution. Most likely SMBHs at high redshift require massive seed black holes (BHs) (10^5 solar masses) created in the gravitational collapse of large gas clouds with subsequent merging. We propose to observe 5 extreme metal-poor blue compact dwarf galaxies, which are the best (local) laboratory for massive BH seed formation and star formation under low metallicity conditions. |

| 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. |
