Abstract	We propose to observe Mrk 926 for 35 ks with XMM and 100 ks with NuSTAR toexplore the Comptonization spectrum of this bright Seyfert 1 galaxy. Previousanalyses of non-simultaneous observations have found a lower limit of the highenergy cut-off of 510 keV, bringing it in disagreement by the temperature limitset by run-away pair production. With the proposed observations we will test,whether Mrk 926s spectrum is consistent with thermal Comptonization or not. Ifit is, we can study its Comptonization spectrum from the UV to the hard X-raysand would obtain key information on the properties of coronae typical forSeyferts. However, if we find that the temperature is inconsistent with thermalComptonization, we can use this dataset to understand which other process could be responsible.

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.
