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…
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…
Explosive nucleosynthesis with fast neutrino-flavor conversion in core-collapse supernovae
Shin-ichiro Fujimoto, Hiroki Nagakura
Fast neutrino-flavor conversion (FFC) is a possible game-changing ingredient in core-collapse supernova (CCSN) theory. In this paper, we examine the impact of FFC on explosive nucl…
Gamma-ray Diagnostics of r-process Nucleosynthesis in the Remnants of Galactic Binary Neutron-Star Mergers
Yukikatsu Terada, Yuya Miwa, Hayato Ohsumi +4
We perform a full nuclear-network numerical calculation of the -process nuclei in binary neutron-star mergers (NSMs), with the aim of estimating -ray emissions from the remna…
Possible Detection of X-Ray Emitting Circumstellar Material in the Synchrotron-Dominated Supernova Remnant RX J 1713.7-3946
Dai Tateishi, Satoru Katsuda, Yukikatsu Terada +4
We report on a discovery of an X-ray emitting circumstellar material knot inside the synchrotron dominant supernova remnant (SNR) RX J1713.7-3946. This knot was previously thought…
