Three-Dimensional Expansion of Iron Ejecta in Cassiopeia A with Chandra and XRISM
Aya Bamba, Tomoki Kadoya, Kouichi Hagino +4
Measurement of the expansion structure of ejecta in supernova remnants (SNRs) provides important information about their explosion mechanism. We combine Chandra proper-motion measu…
Expansion rate of the young, oxygen-rich supernova remnant G292.0+1.8
Maria Aslanidou, Manan Agarwal, Jacco Vink
Core-collapse supernova remnants (CCSNRs) are ideal targets for studying ejecta--interstellar-medium interactions, shock dynamics, and explosion characteristics. G292.0+1.8 is a cl…
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…
Asymmetric distribution of Fe-peak elements in Cassiopeia A revealed by XRISM
Toshiki Sato, Shin-ichiro Fujimoto, Koji Mori +20
The elemental abundances of the Fe-peak elements (such as Cr, Mn, Fe and Ni) and Ti are important for understanding the environment of explosive nuclear burning for the core-collap…
Chlorine and Potassium Enrichment in the Cassiopeia A Supernova Remnant
XRISM collaboration
The elements in the universe are synthesized primarily in stars and supernovae, where nuclear fusion favors the production of even-Z elements. In contrast, odd-Z elements are less…
XRISM Observations of Cassiopeia A: Overview, Atomic Data, and Spectral Models
Paul Plucinsky, Manan Agarwal, Liyi Gu +15
Cassiopeia A (Cas A) is the youngest known core-collapse supernova remnant (SNR) in the Galaxy and is perhaps the best-studied SNR in X-rays. Cas A has a line-rich spectrum dominat…
Mapping Cassiopeia A's silicon/sulfur Doppler velocities with XRISM-Resolve
Jacco Vink, Manan Agarwal, Aya Bamba +22
Young supernova remnants (SNRs) provide crucial insights into explosive nucleosynthesis products and their velocity distribution soon after the explosion. However, these velocities…
Measuring the asymmetric expansion of the Fe ejecta of Cassiopeia A with XRISM/Resolve
Aya Bamba, Manan Agarwal, Jacco Vink +24
The expansion structure of supernova remnants (SNRs) is important for understanding not only how heavy elements are distributed into space, but also how supernovae explode. The eje…
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…
