Simultaneous NuSTAR - XMM-Newton observations of AGN
Abstract
With the launch of NuSTAR in 2012, for the first time spatially resolved observations in the hard X-ray region, far beyond 10 keV, have become possible. NASA's NuSTAR observes from 4 keV to 80 keV. Many observations of NuSTAR are performed simultaneously with ESA's XMM-Newton X-ray observatory whichobserves from 0.3 keV to 12 keV. The soft and hard X-ray spectra together allow determining the continuum, absorption, reflection and emission lines. The broad band coverage of XMM and NuSTAR allows to resolve degeneracies between different spectral components. Joint bservations of the two satellites have become the main tool to study the iron K alpha line emission in the direct environment of black holes. In this region, relativistic effects distort the line profile allowing, amongst others, to constrain the primary X-ray emission region and the spin of supermassive black holes in AGN. The present study aims for the first time to analyze all available simultaneous NuSTAR - XMM-Newton observations in a coherent way with the aim to improve the cross-calibration and characterize physical content of public data.
