Scientific paper

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 10 imes 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.
