XRISM resolve observation 300056010

Object

W49B_West

Abstract

The Suzaku s discovery of recombining plasma in supernova remnants (SNRs) was a surprise because it is never expected in the fiducial Sedov model. We propose to observe the brightest recombining SNR W49B to reveal the origin of this new class of SNRs based on the high-resolution spectroscopy using XRISM/Resolve. We will identify the cooling process that formed the recombining state based on measurements of the electron temperature
