Mapping plasma properties of Cassiopeia A with XRISM/Resolve: a Bayesian analysis via UltraSPEX
Manan Agarwal, Jacco Vink, Liyi Gu +5
Mapping the physical conditions of the shocked plasma of young supernova remnants (SNR) is crucial for understanding their explosion mechanisms, ejecta structure, and large-scale a…
Spatially Resolved Plasma Diagnostics of the Supernova Remnant DEM L71 using the Reflection Grating Spectrometer
Yuki Amano, Yuken Ohshiro, Hiromasa Suzuki +2
We present a spatially resolved high-resolution X-ray spectroscopy of the supernova remnant DEM L71 using the Reflection Grating Spectrometer (RGS) aboard XMM-Newton. Because of th…
Evidence for Charge Exchange Emission in Supernova Remnant N132D from XRISM/Resolve Observations
Liyi Gu, Hiroya Yamaguchi, Adam Foster +24
XRISM has delivered one of its first light observations on N132D, the X-ray brightest supernova remnant in the Large Magellanic Cloud. Utilizing 193 ks of high-resolution X-ray spe…
Dynamics of the intermediate-mass-element ejecta in the Supernova Remnant Cassiopeia A studied with XRISM
Shunsuke Suzuki, Haruto Sonoda, Yusuke Sakai +5
Supernova remnants (SNRs) provide crucial information of yet poorly understood mechanism of supernova explosion. Here we present XRISM high-resolution spectroscopy of the intermedi…
Measurement of the Forward Shock Velocities of the Supernova Remnant N132D Based on the Thermal X-ray Emission
Yoshizumi Okada, Yuken Ohshiro, Shunsuke Suzuki +4
Measuring shock velocities is crucial for understanding the energy transfer processes at the shock fronts of supernova remnants (SNRs), including acceleration of cosmic rays. Here…
Overionized plasma in the supernova remnant Sagittarius A East anchored by XRISM observations
XRISM Collaboration
Sagittarius A East is a supernova remnant with a unique surrounding environment, as it is located in the immediate vicinity of the supermassive black hole at the Galactic center, S…
