Broadband X-ray Spectral Study of Nuclear Structure in Local Obscured Radio Galaxies
arXiv:2306.09195 · doi:10.1093/mnras/stad1836
Abstract
Radio galaxies are a key population to understand the importance of relativistic jets in AGN feedback. We present the results of a systematic, broadband X-ray spectral analysis of hard X-ray selected radio galaxies to investigate their nuclear structures. In this study, we focus on the seven most radio-loud, X-ray obscured narrow line radio galaxies in the \textit{Swift}/BAT 70 month AGN catalog. The spectra from 0.5 keV up to 66 keV obtained with \textit{Suzaku} and \textit{NuSTAR} of six objects are newly analyzed here by utilizing the X-ray clumpy torus model (XCLUMPY), whereas we refer to Ogawa et al. (2021) for the results of Centaurus A. We find that these radio galaxies have similar torus covering fractions compared with radio quiet AGNs at the same Eddington ratios (). This result implies that (1) the torus structure is not an important factor that determines the presence of jets and (2) AGN jets have physically little effect on the torus.
