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 ga…

XRISM Observations of Abell 1795: Evidence for Low Turbulence and Resonant Scattering

Arnab Sarkar, Eric D. Miller, Brian McNamara +10

We present high-resolution X-ray spectroscopic observations of the cool-core galaxy cluster Abell~1795 obtained with XRISM/Resolve. The cluster was observed with two deep pointings…

JWST reveals how black holes are fed: kiloparsec-scale multiphase filaments feed sub-kiloparsec circumnuclear disks

Julie Hlavacek-Larrondo, Hyunseop Choi, Minghao Guo +35

The Centaurus cluster is one of the most important archetypes of radio-mode AGN feedback, with its central galaxy, NGC 4696, launching powerful jets that inflate X-ray cavities and…

High-resolution X-ray spectroscopy with XRISM/Resolve reveals super-Solar abundance ratios in Virgo/M87

J. Martin, A. Simionescu, F. Mernier +26

The chemical composition of the intracluster medium (ICM) provides key insights into the enrichment history of galaxy clusters. However, high-resolution abundance measurements with…

Are X-ray Atmospheres Heated by Turbulent Dissipation? XRISM Constraints

B. R. McNamara, A. C. Fabian, H. R. Russell +5

We evaluate whether dissipation of turbulence injected into hot cluster atmospheres by jets and bubbles can offset radiative cooling flows. No trends are found between atmospheric…
