XRISM xtend observation 201005010

Object

N63A

Abstract

We propose to observe the middle-aged supernova remnant, N63A, in the Large Magellanic Cloud with an exposure time of 300 ks. Our goals of this observation are (1) to detect signatures of charge-exchange (CX) X-ray emission, and (2) to reveal the origin of the Fe K line emission from this remnant. This observation will provide us with the second solid evidence for CX X-ray emission from SNRs after the first detection in N132D with XRISM (private communication). The line broadening of Fe K lines will clarify if the Fe emission arises from Fe-rich ejecta or swept-up interstellar medium. This study cannot be done without XRISM/Resolve having unprecedented spectral resolution above 2 keV.
