A Brush with Turbulence: Probing the ICM Dynamics in the Merging Toothbrush Cluster using XRISM
Anjali Madangarli, Aurora Simionescu, Huub Röttgering +11
The Toothbrush Cluster (1RXS J0603.3+4214) is known for its northern radio relic, radio halo, and highly disturbed X-ray morphology. It shows features of both shock-driven and turb…
Gas Motions in Hydra-A: XRISM Constraints on ICM Kinematics Across Jet-Inflated Cavities
Anwesh Majumder, B. R. McNamara, P. E. J. Nulsen +8
We report on two deep XRISM observations of the central and northern regions of Hydra-A's X-ray atmosphere, covering the bubbles inflated by jets from the central galaxy's active g…
XRISM detection of the 6.4 keV Fe K line in the radio galaxy Cygnus A
Anwesh Majumder, T. Heckman, L. Gu +7
We detail the spectral analysis of a 170 ks XRISM Resolve observation of the core of Cygnus A. The high spectral resolution of Resolve have enabled us to probe the inner accretion…
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…
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…
The bulk motion of gas in the core of the Centaurus galaxy cluster
XRISM collaboration
Galaxy clusters, the largest gravitationally bound structures in the Universe, contain vast amounts of dark matter, galaxies, and hot ionised gas known as the intracluster medium (…
