Description
XRISM, launched in September 2023, offers unprecedented capability in resolving the Fe K band. We use a deep 430 ks observation with XRISM/Resolve to investigate the AGN environment of NGC 3783 and model the structure through Fe Kα emission lines. I will present our latest results on both the narrow Fe Kα line and the relativistic broad iron line.
Our preliminary findings suggest that the narrow neutral Fe Kα line originates from cold, neutral material. Interestingly, a broad emission feature is observed between 5–7 keV. Depending on whether this feature arises from neutral or ionized iron, we are able to constrain the inclination angle of the accretion disk. Our parameter space exploration indicates that multiple black hole spin solutions remain viable. Additionally, scenarios such as a warped accretion disk or partial covering by obscuring material cannot be ruled out based on the current data.
