The BAT AGN Spectroscopic Survey -- XVIII. Searching for Supermassive Black Hole Binaries in the X-rays
Tingting Liu, Michael Koss, Laura Blecha +15
Theory predicts that a supermassive black hole binary (SMBHB) could be observed as a luminous active galactic nucleus (AGN) that periodically varies on the order of its orbital tim…
The Broadband X-ray Spectrum of the X-ray Obscured Type 1 AGN 2MASX J193013.80+341049.5
Nikita Kamraj, Mislav Baloković, Murray Brightman +6
We present results from modeling the broadband X-ray spectrum of the Type 1 AGN 2MASX J193013.80+341049.5 using NuSTAR, Swift and archival XMM-Newton observations. We find this sou…
The nature of the broadband X-ray variability in the dwarf Seyfert galaxy NGC 4395
E. S. Kammoun, E. Nardini, A. Zoghbi +14
We present a flux-resolved X-ray analysis of the dwarf Seyfert 1.8 galaxy NGC 4395, based on three archival and one archival observations. The source is known…
Measuring the Obscuring Column of a Disk Megamaser AGN in a Nearby Merger
Alberto Masini, Andrea Comastri, Ryan C. Hickox +5
Active Galactic Nuclei (AGNs) hosting disk water megamasers are well known to be obscured by large amounts of gas, likely due to the presence along the line of sight of an almost e…
BAT AGN Spectroscopic Survey: XVI. General Physical Characteristics of BAT Blazars
Vaidehi S. Paliya, M. Koss, B. Trakhtenbrot +12
The recently released 105-month {\it Swift}-Burst Alert Telescope (BAT) all-sky hard X-ray survey catalog presents an opportunity to study astrophysical objects detected in the dee…
A deep X-ray view of the bare AGN Ark120. V. Spin determination from disc-Comptonisation efficiency method
D. Porquet, C. Done, J. N. Reeves +13
[Abridged] In our previous work on Ark 120, we found that its 2014 X-ray spectrum is dominated by Comptonisation, while the relativistic reflection emission only originates at tens…
