Compton-Thick AGN in the NuSTAR ERA VII. A joint NuSTAR, Chandra, and XMM-Newton Analysis of Two Nearby, Heavily Obscured Sources

Popis výsledku v původním jazyce

We present the joint Chandra, XMM-Newton, and NuSTAR analysis of two nearby Seyfert galaxies, NGC 3081 and ESO 565-G019. These are the only two having Chandra data in a larger sample of 10 low-redshift (z <= 0.05), candidates Compton-thick (CT) Active Galactic Nuclei selected in the 15-150 keV band with Swift-BAT that were still lacking NuSTAR data. Our spectral analysis, performed using physically motivated models, provides an estimate of both the line-of-sight (l.o.s.) and average (N (H,S )) column densities of the two torii. NGC 3081 has a Compton-thin l.o.s. column density N (H,z ) = [0.58-0.62] x 10(24) cm(-2), but the N (H,S ), beyond the CT threshold (N (H,S ) = [1.41-1.78] x 10(24) cm(-2)), suggests a “patchy” scenario for the distribution of the circumnuclear matter. ESO 565-G019 has both CT l.o.s. and N (H,S ) column densities (N (H,z ) > 2.31 x 10(24) cm(-2) and N (H,S ) > 2.57 x 10(24) cm(-2), respectively). The use of physically motivated models, coupled with the broad energy range covered by the data (0.6-70 keV and 0.6-40 keV, for NGC 3081 and ESO 565-G019, respectively) allows us to constrain the covering factor of the obscuring material, which is C (TOR) = [0.63-0.82] for NGC 3081, and C (TOR) = [0.39-0.65] for ESO 565-G019.
