| Description | We propose to perform sensitive X-ray observations with XMM-Newton of 7 candidate Compton-thick AGN detected by Swift-BAT in the ongoing all-sky survey (15-200 keV). The BAT spectra reveal, through the detection of the photoelectric cut-off (10-20 keV), that these objects are obscured by intervening matter which is Compton-thick. Sensitive X-ray observations are needed to confirm and to study the nature of these sources. A powerful diagnostic for the presence of Compton-thick matter is provided by the intensity and equivalent width of the iron line. XMM-Newton is the most suitable observatory to study such objects as its sensitivity is 10x larger than Swift-XRT at 6 keV. |

| 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. |
