Star Formation Histories and Stellar Dynamics in the Central Galaxies of RX J0820.9+0752, A1835, and PKS 0745-191
Marie-Joëlle Gingras, B. R. McNamara, Alison L. Coil +5
We present Keck Cosmic Web Imager observations of stellar populations in three galaxies lying at the centers of cooling flow clusters. All three host rich molecular gas reservoirs…
Hidden (absorbed) Cooling Flows V: Groups and Galaxies including Spirals
A. C. Fabian, J. S. Sanders, G. J. Ferland +4
Cooling flows are observed in X-ray studies of the centres of cool core clusters, galaxy groups and individual elliptical galaxies. They are partly hidden from direct view by embed…
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…
Velocity Structure Correlations between the Nebular, Molecular, and Atmospheric Gases in the Cores of Four Cool Core Clusters
Muzi Li, B. R. McNamara, Alison L. Coil +6
We investigate the velocity structure of nebular gas in the central galaxies of four clusters: Abell 1835, PKS 0745-191, Abell 262, and RXJ0820.9+0752, using data from the Keck Cos…
Gas Perturbations in Hot Smooth Atmospheres X-ray Surface Brightness Fluctuations in Smooth Galaxy Cluster Atmospheres
Muzi Li, B. R. McNamara, Irina Zhuravleva
We measure surface brightness fluctuations in Chandra X-ray images of the cores of the galaxy clusters Abell 2029, Abell 2151, Abell 2107, RBS0533, and RBS0540. Their relatively st…
HST Observations within the Sphere of Influence of the Powerful Supermassive Black Hole in PKS0745-191
Julie Hlavacek-Larrondo, Hyunseop Choi, Minghao Guo +18
We present Space Telescope Imaging Spectrograph observations from the Hubble Space Telescope of the supermassive black hole (SMBH) at the center of PKS0745-191, a brightest cluster…
