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 VI: The observed Compton-thick fraction in the Local Universe

N. Torres-Albà, S. Marchesi, X. Zhao +11

We present the analysis of simultaneous NuSTAR and XMM-Newton data of 8 Compton-thick (CT-) active galactic nuclei (AGN) candidates selected in the Swift-Burst Alert Telescope (BAT…

The properties of the AGN torus as revealed from a set of unbiased NuSTAR observations

X. Zhao, S. Marchesi, M. Ajello +4

The obscuration observed in active galactic nuclei (AGN) is mainly caused by dust and gas distributed in a torus-like structure surrounding the supermassive black hole (SMBH). Howe…

A broadband X-ray study of a sample of AGNs with [OIII] measured inclinations

X. Zhao, S. Marchesi, M. Ajello +2

In modeling the X-ray spectra of active galactic nuclei (AGNs), the inclination angle is a parameter that can play an important role in analyzing the X-ray spectra of AGN, but it h…

Compton-thick AGN in the NuSTAR era IV: A deep NuSTAR and XMM-Newton view of the candidate Compton thick AGN in ESO 116-G018

X. Zhao, S. Marchesi, M. Ajello

We present the 2--78 keV spectral analysis of the deep NuSTAR and XMM-Newton observation of a nearby Seyfert 2 galaxy, ESO 116-G018, which is selected as a candidate Compton-thick…

Compton-thick AGN in the NuSTAR era II: A deep NuSTAR and XMM-Newton view of the candidate Compton thick AGN in NGC 1358

X. Zhao, S. Marchesi, M. Ajello +4

We present the combined NuSTATR and XMM-Newton 0.6-79 keV spectral analysis of a Seyfert 2 galaxy, NGC 1358, which we selected as a candidate Compton thick (CT-) active galactic nu…
