Spectral Analysis of the Egress and Ingress Phases of Cen X-3 with XRISM/Resolve

J. Planelles-Villalva, L. Gu, J. J. Rodes-Roca +7

We investigate the phase-resolved X-ray spectral evolution of the high-mass X-ray binary Cen X-3 across eclipse ingress and egress, using two out-of-eclipse intervals as references…

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…

Benchmark of the Fe XXV R ratio in photoionized plasma during eclipse of Centaurus X-3 with XRISM/Resolve

Yuto Mochizuki, Masahiro Tsujimoto, Maurice A. Leutenegger +6

The R ratio is a useful diagnostic of the X-ray emitting astrophysical plasmas defined as the intensity ratio of the forbidden over the inter-combination lines in the K line com…

Origin of the complex iron line structure and spectral variation in Mrk 766

Yuto Mochizuki, Misaki Mizumoto, Ken Ebisawa

Complex Fe-K emission/absorption line features are commonly observed in the 6--11 keV band from Active Galactic Nuclei (AGN). These features are formed in various physical componen…
