The eROSITA instrument on-board Spectrum-Roentgen-Gamma openParSRGclosePar has performed the first imaging all-sky survey in the hard X-ray openPar2-10keVclosePar band. The final survey will be over 30 times deeper than previous hard X-ray surveys comma yielding a large and very pure sample of AGN. Combining eROSITA data with observations from other multi-wavelength missions comma a detailed picture of the AGN population can be constructed. We propose simultaneous NuSTAR+XMM follow up observations of a group of hard X-ray selected AGN observed with eROSITA. This pilot study will demonstrate the power of joint NuSTAR and XMM observations to break degeneracies present in different spectral models comma motivating future joint NuSTAR comma XMM and eROSITA investigations.
