THE FIRST UNAMBIGUOUS DETECTION OF THE X-RAY BROAD-LINE REGION
For a long period, research on the broad line region (BLR) in active galactic nuclei (AGN) has predominantly relied on UV/optical spectroscopy. The XRISM/Resolve X-ray spectrometer offers an unprecedented opportunity to explore the X-ray BLR. This proposal aims at utilising the high spectral resolution of Resolve to probe the BLR in NGC 7213, a nearby, bright, and unabsorbed AGN where the low-ionisation Fe Ka is broadly consistent with being produced by the BLR. The proposed XRISM observation will unambiguously establish the origin of the low-ionization Fe K emission line in this target. This will provide a novel perspective, unveiling the hot phases of BLR and its overall ionisation structure.
