An X-ray Significantly Variable, Luminous, Type 2 Quasar at z = 2.99 with a Massive Host Galaxy
Xiurui Zhao, Stefano Marchesi, Marco Ajello +8
We present a comprehensive X-ray analysis and spectral energy distribution (SED) fitting of WISEA J171419.96+602724.6, an extremely luminous type 2 quasar at = 2.99. The source…
Compton-thick AGN in the NuSTAR Era X: Analysing seven local CT-AGN candidates
Dhrubojyoti Sengupta, Stefano Marchesi, Cristian Vignali +14
We present the broad-band X-ray spectral analysis (0.6-50 keV) of seven Compton-Thick active galactic nuclei (CT-AGN; line-of-sight, l.o.s., column density cm) ca…
A New Mid-Infrared and X-ray Machine Learning Algorithm to Discover Compton-thick AGN
Ross Silver, Núria Torres-Alba, Xiurui Zhao +4
We present a new method to predict the line-of-sight column density (NH) values of active galactic nuclei (AGN) based on mid-infrared (MIR), soft, and hard X-ray data. We developed…
A Simple Method for Predicting Variability in Active Galactic Nuclei
Isaiah Cox, Nuria Torres-Alba, Stefano Marchesi +4
The unified model of active galactic nuclei (AGN) includes a toroidal obscuring structure to explain the differences between Type I and Type II AGN as an effect of inclination angl…
Hydrogen Column Density Variability in a Sample of Local Compton-Thin AGN
N. Torres-Albà, S. Marchesi, X. Zhao +4
We present the analysis of multiepoch observations of a set of 12 variable, Compton-thin, local (z<0.1) active galactic nuclei (AGN) selected from the 100-month BAT catalog. We ana…
Compton-thick AGN in the NuSTAR Era. IX. A Joint NuSTAR and XMM-Newton Analysis of Four Local AGN
Ross Silver, Nuria Torres-Alba, Xiurui Zhao +7
We present the results of the broadband X-ray spectral analysis of simultaneous NuSTAR and XMM-Newton observations of four nearby Compton-thick active galactic nuclei (AGN) candida…
