NGC3516
In an AGN, a Broad-Line Region (BLR) is one of the most important structures deeply related to the evolution of black holes and feedback to galaxies. However, its formation mechanism is still unclear. Therefore, we propose a 160 ksec XRISM observation on a changing-state AGN NGC 3516, in which a BLR is likely being formed by an outflow in addition to an inflow. With Resolve, we can decompose Fe-K lines from a BLR and a torus, and compare the flux and profile of the BLR line to those in our prior study (Noda+23). We also aim to detect weak Fe XXV/XXVI absorption lines by the outflow. Xtend enables us to identify a soft X-ray continuum that produces the outflow via radiation pressure. By these, we constrain the contributions of inflow and outflow to the BLR formation for the first time.
