Observations of AGN-driven feedback: dynamics and ionization of the filaments in M87

Camille Poitras, Marie-Lou Gendron-Marsolais, Valeria Olivares +9

We present a comprehensive kinematic and ionization analysis of the warm ionized filaments ( K) in M87, the central galaxy of the Virgo cluster, using new integral field spec…

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…

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…

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 constraints on unidentified X-ray emission lines, including the 3.5 keV line, in the stacked spectrum of ten galaxy clusters

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +150

We stack 3.75 Megaseconds of early XRISM Resolve observations of ten galaxy clusters to search for unidentified spectral lines in the 2.5-15 keV band (rest frame), including t…
