FE K-BAND SIGNATURES: THE KEY TO MAPPING THE LOW MASS SYSTEM OF NGC 4051
Precise profile measurements of features in the Fe K band will allow unprecedented constraints on the reprocessor, within a framework defined by the tightly-constrained black hole mass that makes NGC 4051 a compelling target for XRISM Cycle 1. We request 150 ks observation to: (i) determine the precise origin of the Fe Ka line, (ii) measure the kinematics of the ionized outflow and (iii) detect and identify lines seen red-ward of Fe Ka.
