Broadband X-ray Spectral Study of Nuclear Structure in Local Obscured Radio Galaxies

Yuya Nakatani, Yoshihiro Ueda, Claudio Ricci +6

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…

Probing the origin of the two-component structure of broad line region by reverberation mapping of an extremely variable quasar

Shumpei Nagoshi, Fumihide Iwamuro, Satoshi Yamada +5

The physical origins of quasar components, such as the broad line region (BLR) and dust torus, remain under debate. To gain insights into them, we focused on Changing-State Quasars…

eROSITA Final Equatorial-Depth Survey (eFEDS): eFEDS X-ray view of WERGS Radio Galaxies selected by the Subaru/HSC and VLA/FIRST survey

Kohei Ichikawa, Takuji Yamashita, Andrea Merloni +19

We construct the eROSITA X-ray catalog of radio galaxies discovered by the WERGS survey that is made by the cross-matching of the wide-area Subaru/HSC optical survey and VLA/FIRST…
