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…

The weak neutral Fe fluorescence line and long-term X-ray evolution of the Compton-thick AGN in NGC 7674

P. Gandhi, A. Annuar, G. B. Lansbury +26

We present X-ray observations of the active galactic nucleus (AGN) in NGC 7674. The source shows a flat X-ray spectrum, suggesting that it is obscured by Compton-thick gas…

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-…

NuSTAR observations of water megamaser AGN

A. Masini, A. Comastri, M. Baloković +18

Aims. Study the connection between the masing disk and obscuring torus in Seyfert 2 galaxies. Methods. We present a uniform X-ray spectral analysis of the high energy properties of…

Suzaku Confirms NGC~3660 is an Unabsorbed Seyfert 2

E. Rivers, M. Brightman, S. Bianchi +3

An enigmatic group of objects, unabsorbed Seyfert 2s may have intrinsically weak broad line regions, obscuration in the line of sight to the BLR but not to the X-ray corona, or so…

The NuSTAR view of reflection and absorption in NGC 7582

E. Rivers, M. Baloković, P. Arévalo +14

NGC 7582 is a well-studied X-ray bright Seyfert 2 with moderately heavy (~cm), highly variable absorption and strong reflection spectral fea…
