Energy shift of Fe-K fluorescence lines due to low ionization demonstrated with XRISM in Centaurus X-3

Yutaro Nagai, Teruaki Enoto, Masahiro Tsujimoto +13

The Fe K fluorescence line at 6.4 keV is a powerful probe of cold matter surrounding X-ray sources and has been widely used in various astrophysical contexts. The X-ray microcal…

A XRISM/Resolve view of the dynamics in the hot gaseous atmosphere of M87

XRISM Collaboration, M. Audard, H. Awaki +138

The XRISM/Resolve microcalorimeter directly measured the gas velocities in the core of the Virgo Cluster, the closest example of AGN feedback in a cluster. This proximity allows us…

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/Resolve reveals the complex iron structure of NGC 7213: Evidence for radial stratification between inner disk and broad-line region

E. Kammoun, T. Kawamuro, K. Murakami +48

We present the first high-resolution X-ray spectrum of NGC 7213 obtained with XRISM/Resolve, supported by simultaneous XMM-Newton, NuSTAR, and SOAR optical data. The XRISM spectrum…

XRISM High-resolution Spectroscopy of SS 433: Evidence of Decreasing Line-of-Sight Velocity Dispersion along the Jet

Megumi Shidatsu, Shogo Kobayashi, Yusuke Sakai +6

We report on the jet structure in SS 433 based on X-ray high resolution spectroscopy with the XRISM/Resolve. The source was observed over 5 days covering both inside and outside an…

Decadal brightening in the northeastern non-thermal filament of Cassiopeia A

Nao Kominato, Toshiki Sato, Yusuke Sakai +2

We present the decadal brightening of non-thermal emission flux in the northeastern filament of the young supernova remnant Cassiopeia A (Cas A), which highlights dynamic processes…
