Understanding the nature of soft X-ray emission in radio-loud Type 2 AGN

We propose to observe the bright quasar 3C 234 for 160 ks using the RGS as primeinstrument. This observation will provide the first deep highresolution Xrayspectrum ever obtained of a narrowline radioloud AGN. Our preliminary RGS dataof April 2019 display, for the first time, a clear evidence of soft Xrayemission lines in an obscured radioloud AGN. The superior spectral quality thatwill be achieved with the new observation will allow us to unambiguouslydetermine the physical conditions of the ionized gas. This will provide anunprecedented insights on the longstanding debate about the nature of the softXray emission in radioloud type 2 AGN. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
