The NuSTAR View of the Seyfert 2 Galaxy NGC 4388
N. Kamraj, E. Rivers, F. A. Harrison +2
We present analysis of NuSTAR X-ray observations in the 3-79 keV energy band of the Seyfert 2 galaxy NGC 4388, taken in 2013. The broadband sensitivity of NuSTAR, covering the Fe K…
A New Population of Compton-Thick AGN Identified Using the Spectral Curvature Above 10 keV
Michael J. Koss, R. Assef, M. Balokovic +18
We present a new metric that uses the spectral curvature (SC) above 10 keV to identify Compton-thick AGN in low-quality Swift BAT X-ray data. Using NuSTAR, we observe nine high SC-…
The Multi-Layer Variable Absorbers in NGC 1365 Revealed by XMM-Newton and NuSTAR
E. Rivers, G. Risaliti, D. J. Walton +15
Between July 2012 and February 2013, NuSTAR and XMM-Newton performed four long-look joint obser- vations of the type 1.8 Seyfert, NGC 1365. We have analyzed the variable absorption…
Determining the covering factor of Compton-thick active galactic nuclei with NuSTAR
M. Brightman, M. Balokovic, D. Stern +19
The covering factor of Compton-thick obscuring material associated with the torus in active galactic nuclei (AGN) is at present best understood through the fraction of sources exhi…
