No Signatures of Black-Hole Spin in the X-ray Spectrum of the Seyfert 1 Galaxy Fairall 9
Tahir Yaqoob, Tracey Jane Turner, Malachi M. Tatum +2
Fairall 9 is one of several type 1 active galactic nuclei for which it has been claimed that the angular momentum (or spin) of the supermassive black hole can be robustly measured,…
A Compton-thin Solution for the Suzaku X-ray Spectrum of the Seyfert 2 Galaxy Mkn 3
T. Yaqoob, M. M. Tatum, A. Scholtes +2
Mkn 3 is a Seyfert 2 galaxy that is widely regarded as an exemplary Compton-thick AGN. We study the Suzaku X-ray spectrum using models of the X-ray reprocessor that self-consistent…
A Focused, Hard X-ray Look at Arp 299 with NuSTAR
A. Ptak, A. Hornschemeier, A. Zezas +19
We report on simultaneous observations of the local starburst system Arp 299 with NuSTAR and Chandra, which provides the first resolved images of this galaxy up to energies of ~ 45…
The Global Implications of the Hard X-ray Excess in Type 1 AGN
M. M. Tatum, T. J. Turner, L. Miller +1
Recent evidence for a strong 'hard excess' of flux at energies > 20 keV in some Suzaku observations of type 1 Active Galactic Nuclei (AGN) has motivated an exploratory study of the…
Modeling the Fe K Line Profiles in Type I AGN with a Compton-Thick Disk Wind
M. M. Tatum, T. J. Turner, S. A. Sim +4
We have modeled a small sample of Seyfert galaxies that were previously identified as having simple X-ray spectra with little intrinsic absorption. The sources in this sample all c…
X-ray Signatures of Circumnuclear Gas in AGN
T. J. Turner, L. Miller, M. Tatum
X-ray spectra of AGN are complex. X-ray absorption and emission features trace gas covering a wide range of column densities and ionization states. High resolution spectra show the…
