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 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…
Constraining gas motion and non-thermal pressure beyond the core of the Abell 2029 galaxy cluster with XRISM
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +137
We report a detailed spectroscopic study of the gas dynamics and hydrostatic mass bias of the galaxy cluster Abell 2029, utilizing high-resolution observations from XRISM Resolve.…
A XRISM Observation of the Archetypal Radio-Mode Feedback System Hydra-A: Measurements of Atmospheric Motion and Constraints on Turbulent Dissipation
Tom Rose, B. R. McNamara, Julian Meunier +14
We present XRISM Resolve observations centered on Hydra-A, a redshift z = 0.054 brightest cluster galaxy which hosts one of the largest and most powerful FR-I radio sources in the…

Tom Rose, B. R. McNamara, F. Combes +8
We present new ALMA observations of CO, CN, CS, HCN and HCO absorption seen against the bright and compact radio continuum sources of eight massive galaxies. Combined with ar…
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…
The Close AGN Reference Survey (CARS): An interplay between radio jets and AGN radiation in the radio-quiet AGN HE 0040-1105
M. Singha, N. Winkel, S. Vaddi +14
We present a case study of HE 0040-1105, an unobscured radio-quiet AGN at a high accretion rate (Eddington ratio = 0.19+/-0.04). This particular AGN hosts an ionized gas outflow wi…
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…
Circumnuclear Medium around the Central AGN in a Cool-Core Cluster, Abell 1644-South
Junhyun Baek, Aeree Chung, Alastair Edge +3
We present the circumnuclear multi-phase gas properties of the brightest cluster galaxy (BCG) in the center of Abell 1644-South. A1644-S is the main cluster in a merging system, wh…
Gas condensation in Brightest Group Galaxies unveiled with MUSE
V. Olivares, P. Salome, S. L. Hamer +18
The origin of the cold gas in central galaxies in groups is still a matter of debate. We present Multi-Unit Spectroscopic Explorer (MUSE) observations of 18 optically selected loca…
