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…
Exploring the dynamics of the Coma galaxy cluster by mapping its X-ray emission line profiles with XRISM
Kosei Sakai, Kazuhiro Nakazawa, Maxim Markevitch +17
The intracluster medium (ICM) in merging galaxy clusters exhibits turbulence and bulk flows. Unraveling these components is crucial not only for elucidating the geometry of the clu…
XRISM reveals sloshing-driven gas motions in the core of Abell 2029
Yuusuke Uchida, Yuna Saito, Naomi Ota +13
We investigate the velocity structure of the intracluster medium (ICM) in the core of the relaxed cool-core cluster Abell 2029 using XRISM Resolve spectroscopy. We analyze combined…
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…
XRISM High-Resolution X-ray Spectroscopy of Cygnus X-1 -- Orbital and Short-Term Variability of Iron Absorption
Kaito Ninoyu, Shinya Yamada, Natalie Hell +19
We present the first high-resolution spectroscopy of the black hole high-mass X-ray binary Cygnus X-1 with XRISM, including orbital-phase-resolved analyses and tentative evidence o…
XRISM High-Resolution X-ray Spectroscopy of Cygnus X-1 -- highly ionized Iron absorption structures
Shinya Yamada, Natalie Hell, Elisa Costantini +18
We present the first high-resolution X-ray spectral analysis of Cygnus X-1 using XRISM. The observation was carried out from April 7 to 10, 2024, covering the orbital phase range 0…
