We propose to observe with XMM-Newton 3 sources belonging to a new AGN class:the naked AGN. Preliminary snapshot observations with Chandra demonstrate thatthese objects are easily detectable and no nearby sources are present within aradius of 1 arcminute. Based on optical studies, these AGN appear as type2 fromthe spectral point of view, and as type1 AGN for their variability. The X-raydata, which are unambiguously associated with genuine nuclear activity, arecrucial to shed light on the nature of these enigmatic sources, which may berepresentative of a large class of AGN. XMM-Newton unique capabilities arecrucial to: 1) Investigate the continuum spectrum and the Fe K line; 2) Studythe flux and spectral variability; 3)Compare the SED with those of type1 and type2 AGN.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
