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…

Diagnosing the Fe line complex of the intracluster medium by XRISM high-resolution spectroscopy

K. Fukushima, L. Hirata, N. Y. Yamasaki +17

We aim to test the validity of the CIE framework in the ICM by performing line diagnostics based mainly on resolved Fe-K emission lines. Methods. We analyse Resolve full-array spec…

Probable Detection of a Cooler Gas Component in the Perseus Cluster with XRISM

Julian Meunier, Brian R. McNamara, Aurora Simionescu +36

We present an analysis of the temperature structure of the Perseus cluster atmosphere using XRISM Resolve observations. The average temperature rises from 3.3 keV near the nucleus…

Dynamics of AGN feedback in the X-ray bright East and Southwest arms of M87, mapped by XRISM

A. Simionescu, C. Kilbourne, H. R. Russell +24

As the central galaxy in the nearest cluster, M87 provides the best spatial resolution for disentangling the complex interactions between AGN jets and the surrounding environment.…

Spectrally Resolved Gas Kinematics in Cygnus A: XRISM Detects AGN Jet-induced Velocity Dispersion in Multi-temperature Gas

Anwesh Majumder, T. Heckman, J. Meunier +8

We report spectral analysis on a 170 ks XRISM \textit{Resolve} exposure of the core of Cygnus A. Analyzing the full field of view spectrum in the keV band, we find evide…

Indications of an offset merger in Abell 3667

Y. Omiya, K. Nakazawa, T. Tamura +13

Abell 3667 is a nearby merging cluster with a prominent cold front and a pair of two bright radio relics. Assuming a head-on merger, the origin of the cold front is often considere…

Enrichment of the hot intracluster medium: observations

F. Mernier, V. Biffi, H. Yamaguchi +7

Four decades ago, the firm detection of an Fe-K emission feature in the X-ray spectrum of the Perseus cluster revealed the presence of iron in its hot intracluster medium (ICM). Wi…
