Probing the coronal properties of Swift/BAT-selected Seyfert 1 AGN

The corona is an integral component of Active Galactic Nuclei (AGN), creating the bulk of the continuum X-ray emission via Compton upscattering of UV and optical photons from the inner accretion disk by coronal electrons. The X-ray continuum has a characteristic cutoff at an energy that is determined by the physical properties of the coronal plasma, such as temperature. In this work, we use broadband (0.6 - 79 keV) X-ray spectroscopic data of Seyfert 1 AGN selected from the Swift/BAT 70-month hard X-ray catalog to explore possible correlations between coronal parameters, such as the dependence of the high energy cutoff on optical depth, Eddington ratio and black hole mass. We use hard X-ray data from the NuSTAR observatory, which has enabled detailed broadband modeling of the X-ray spectra of AGN, allowing constraints to be placed on the high-energy cutoff of the X-ray continuum. We use our large sample of NuSTAR-observed AGN with high signal-to-noise spectra to also investigate the relation between X-ray photon index and Eddington ratio, and we compare our findings to relations previously reported in the literature.
