Description | We propose XMM-Newton observations of 8 new AGN detected by Swift-BAT in the all-sky survey (15 -200 keV). The available X-ray spectra (BAT and XRT) show that these sources are obscured by intervening matter with hydrogen column density of Log(N_H) > 23. Sensitive X-ray observations are needed to understand whether these sources are Compton-thick and to study their physical properties. A powerful diagnostic for the presence of Compton-thick matter ( Log(N_H) > 24) is provided by the equivalent width of the iron line. XMM-Newton is the most suitable observatory to study such objects as its sensitivity is 10times larger than Swift-XRT at 6 keV. The XMM observations of these objects will complete the 2-10 keV observations of the whole all-sky sample of AGN detected by BAT. |

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. |
