XRISM Discovery of Multiple Ionized Fe-K Emission and Absorption Components in Centaurus A
Taishu Kayanoki, Yasushi Fukazawa, Junjie Mao +13
We present the first clear detection of ionized Fe-K emission and absorption components in the nearby radio galaxy Centaurus A, revealed by the high-resolution XRISM/Resolve detect…
X-ray line diagnostics of the multi-phase gas in the Centaurus cluster core with XRISM/Resolve
Marie Kondo, Kotaro Fukushima, Kazunori Suda +18
We report the multi-temperature structure of the intracluster medium (ICM) in the Centaurus cluster core observed with XRISM/Resolve. Thanks to its high energy resolution, Resolve…
Chemical composition and enrichment of the Centaurus cluster core seen by XRISM/Resolve
F. Mernier, K. Fukushima, A. Simionescu +16
Hot, X-ray emitting atmospheres pervading galaxy clusters are rich in metals, which have been synthesised and released by asymptotic giant branch (AGB) stars, core-collapse superno…
XRISM analysis of the complex Fe K line in Centaurus A
David Bogensberger, Yuya Nakatani, Tahir Yaqoob +14
We analyze the high-resolution XRISM/Resolve spectrum of the Fe K emission line of the nearest active galactic nucleus, in Centaurus A. The line features two narrow and resolve…
