Measuring the ICM velocity structure within the A3266 galaxy cluster
E. Gatuzz, J. Sanders, A. Liu +7
We present a detailed analysis of the velocity structure of the hot intracluster medium (ICM) within the A3266 galaxy cluster, including new observations taken between June and Nov…
A molecular absorption line survey toward the AGN of Hydra-A
Tom Rose, A. C. Edge, F. Combes +16
We present Atacama Large Millimeter/submillimeter Array observations of the brightest cluster galaxy Hydra-A, a nearby () giant elliptical galaxy with powerful and extende…
Constraining cold accretion onto supermassive black holes: molecular gas in the cores of eight brightest cluster galaxies revealed by joint CO and CN absorption
Tom Rose, A. C. Edge, F. Combes +18
To advance our understanding of the fuelling and feedback processes which power the Universe's most massive black holes, we require a significant increase in our knowledge of the m…
Ubiquitous cold and massive filaments in cool core clusters
V. Olivares, P. Salomé, F. Combes +20
Multi-phase filamentary structures around Brightest Cluster Galaxies are likely a key step of AGN-feedback. We observed molecular gas in 3 cool cluster cores: Centaurus, Abell S110…
ASTRO-H White Paper - Clusters of Galaxies and Related Science
T. Kitayama, M. Bautz, M. Markevitch +22
The next generation X-ray observatory ASTRO-H will open up a new dimension in the study of galaxy clusters by achieving for the first time the spectral resolution required to measu…
Does absorption against AGN reveal supermassive black hole accretion?
Tom Rose, B. R. McNamara, F. Combes +7
Galaxies often contain large reservoirs of molecular gas which shape their evolution. This can be through cooling of the gas -- which leads to star formation, or accretion onto the…
The velocity structure of the Intracluster Medium of the Centaurus cluster
E. Gatuzz, J. S. Sanders, R. Canning +7
There are few direct measurements of ICM velocity structure, despite its importance for understanding clusters. We present a detailed analysis of the velocity structure of the Cent…
Deep and narrow CO absorption revealing molecular clouds in the Hydra-A brightest cluster galaxy
Tom Rose, A. C. Edge, F. Combes +20
Active galactic nuclei play a crucial role in the accretion and ejection of gas in galaxies. Although their outflows are well studied, finding direct evidence of accretion has prov…
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…
Chemical enrichment of the ICM within the Virgo cluster I: radial profiles
Efrain Gatuzz, J. Sanders, K. Dennerl +8
We present a detailed analysis of the elemental abundances distribution of the Virgo cluster using {\it XMM-Newton} observations. We included in the analysis a new EPIC-pn energy s…
A massive multiphase plume of gas in Abell 2390's brightest cluster galaxy
Tom Rose, B. R. McNamara, F. Combes +6
We present new ALMA CO(2-1) observations tracing solar masses of molecular gas in Abell 2390's brightest cluster galaxy, where half the gas is located in a one…

E. Gatuzz, J. Sanders, A. Liu +7
We present a detailed study of the elemental abundances distribution of the intracluster medium (ICM) within the A3266 cluster using {\it XMM-Newton} observations. This analysis us…
Science of High Resolution X-ray Imaging
H. L. Marshall, K. Weaver, M. Schattenburg +34
This report summarizes potential studies of the Hi-ReX Science Analysis Group for an Ultra-High Angular Resolution X-ray Observatory. Many potential science cases are presented, sp…
Measuring the ICM velocity structure in the Ophiuchus cluster
Efrain Gatuzz, J. S. Sanders, K. Dennerl +8
We have found evidence of bulk velocities following active galactic nucleus (AGN) bubbles in the Virgo cluster and galaxy motions in the Centaurus cluster. In order to increase the…
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…
