X-ray Coronal Properties of Swift/BAT-Selected Seyfert 1 Active Galactic Nuclei

Nikita Kamraj, Murray Brightman, Fiona A. Harrison +9

The corona is an integral component of Active Galactic Nuclei (AGN) which produces the bulk of the X-ray emission above 1--2 keV. However, many of its physical properties and the m…

The Field Substellar Mass Function Based on the Full-sky 20-pc Census of 525 L, T, and Y Dwarfs

J. Davy Kirkpatrick, Christopher R. Gelino, Jacqueline K. Faherty +49

We present final Spitzer trigonometric parallaxes for 361 L, T, and Y dwarfs. We combine these with prior studies to build a list of 525 known L, T, and Y dwarfs within 20 pc of th…

NuSTAR Survey of Obscured Swift/BAT-selected Active Galactic Nuclei: II. Median High-energy Cutoff in Seyfert II Hard X-ray Spectra

M. Baloković, F. A. Harrison, G. Madejski +16

Broadband X-ray spectroscopy of the X-ray emission produced in the coronae of active galactic nuclei (AGN) can provide important insights into the physical conditions very close to…

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 Spectral Energy Distributions of Active Galactic Nuclei

M. J. I. Brown, K. J. Duncan, H. Landt +5

We present spectral energy distributions (SEDs) of 41 active galactic nuclei, derived from multiwavelength photometry and archival spectroscopy. All of the SEDs span at least 0.09…

Probing the Black Hole Engine with Measurements of the Relativistic X-ray Reflection Component

Javier A. García, Matteo Bachetti, David R. Ballantyne +21

Over the last decades X-ray spectroscopy has proven to be a powerful tool for the estimation of black hole spin and several other key parameters in dozens of AGN and black hole X-r…
