Fundamental X-ray Corona Parameters of Swift/BAT AGN
  While X-ray emission from active galactic nuclei (AGN) is common, the
detailed physics behind this emission is not well understood. This is in part
because high quality broadband spectra are required to precisely derive
fundamental parameters of X-ray emission such as the photon index, folding
energy, and reflection coefficient. Here we present values of such parameters
for 33 AGN observed as part of the 105 month Swift/BAT campaign and with
coordinated archival XMM-Newton and NuSTAR observations. We look for
correlations between the various coronal parameters in addition to correlations
between coronal parameters and physical properties such as black hole mass and
Eddington ratio. Using our empirical model, we find good fits to almost all of
our objects. The folding energy was constrained for 30 of our 33 objects. When
comparing Seyfert 1 - 1.9 to Seyfert 2 galaxies, a K-S test indicates that
Seyfert 2 AGN have lower Eddington ratios and photon indices than Seyfert 1 -
1.9 objects with p-values of $5.6 \times 10^{-5}$ and $7.5 \times 10^{-3}$
respectively. We recover a known correlation between photon index and
reflection coefficient as well as the X-ray Baldwin effect. Finally, we find
that the inclusion of the high energy Swift BAT data significantly reduces the
uncertainties of spectral parameters as compared to fits without the BAT data.
