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…
[O III] and X-ray Properties of a Complete Sample of Hard X-ray Selected AGNs in the Local Universe
Y. Ueda, Y. Hashimoto, K. Ichikawa +11
We study the correlation between the [O III] and X-ray luminosities of local Active Galactic Nuclei (AGNs), using a complete, hard X-ray ( keV) selected sample in the S…
A hard X-ray view of the soft excess in AGN
Rozenn Boissay, Claudio Ricci, Stéphane Paltani
An excess of X-ray emission below 1 keV, called soft excess, is detected in a large fraction of Seyfert 1-1.5s. The origin of this feature remains debated, as several models have b…
On the relation of optical obscuration and X-ray absorption in Seyfert galaxies
L. Burtscher, R. I. Davies, J. Gracia-Carpio +15
The optical classification of a Seyfert galaxy and whether it is considered X-ray absorbed are often used interchangeably. But there are many borderline cases and also numerous exa…
BAT AGN Spectroscopic Survey II: X-ray Emission and High Ionization Optical Emission Lines
Simon Berney, Michael Koss, Benny Trakhtenbrot +17
We investigate the relationship between X-ray and optical line emission in 340 nearby AGN selected above 10 keV using Swift BAT. We find a weak correlation between the extinction c…
NuSTAR Observations of the Compton-thick Active Galactic Nucleus and Ultraluminous X-ray Source Candidate in NGC 5643
A. Annuar, P. Gandhi, D. M. Alexander +22
We present two NuSTAR observations of the local Seyfert 2 active galactic nucleus (AGN) and an ultraluminous X-ray source (ULX) candidate in NGC 5643. Together with archival data f…
