The eROSITA instrument on-board Spectrum-Roentgen-Gamma (SRG) has performedthe first imaging all-sky survey in the hard X-ray (2-10keV) band. Thefinal survey will be over 30 times deeper than previous hard X-ray surveys,yielding a large and very pure sample of AGN. Combining eROSITA data withobservations from other multi-wavelength missions, a detailed pictureof the AGN population can be constructed. We propose simultaneous NuSTAR+XMMfollow up observations of a group of hard X-ray selected AGN observed witheROSITA. This pilot study will demonstrate the power of joint NuSTAR andXMM observations to break degeneracies present in different spectral models,motivating future joint NuSTAR, XMM and eROSITA investigations.

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.
