The Complex X-Ray Obscuration Environment in the Radio-loud Type 2 Quasar 3C 223
Published 2023-01-01“…3C 223 is a radio-loud, Type 2 quasar at z = 0.1365 with an intriguing X-ray Multi-mirror Mission (XMM)-Newton spectrum that implicated it as a rare, Compton-thick ( N _H ≳ 1.25 × 10 ^24 cm ^−2 ) active galactic nucleus (AGN). We obtained contemporaneous XMM-Newton and Nuclear Spectroscopic Telescope Array (NuSTAR) spectra to fit the broadband X-ray spectrum with the physically motivated MYT orus and borus02 models. …”

Evidence of a Massive Stellar Disruption in the X-Ray Spectrum of ASASSN-14li
Published 2023-01-01“…Flows of the kind seen in the X-ray spectrum of ASASSN-14li were not clearly predicted in simulations of TDEs; this left open the possibility that the observed absorption might be tied to gas released in prior active galactic nucleus (AGN) activity. However, the abundance pattern revealed in this analysis points to a single star rather than a standard AGN accretion flow comprised of myriad gas contributions. …”
