The Quiescent Sloshing Core of Abell 496 with XRISM
Angie Veronica, Thomas H. Reiprich, Naomi Ota +9
Gas motions provide insight into the dynamical history and physical processes within galaxy clusters. We investigate the kinematics of the ICM in the core of A496, a nearby, X-ray…
The splash beneath the largest radio bubble in a cluster core
H. R. Russell, P. E. J. Nulsen, A. C. Fabian +3
We present a 100 ks XRISM Resolve observation of the Ophiuchus cluster that measures turbulence and bulk motion in the wake of the largest radio bubble on the sky. We detect a sign…
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…
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…
Hidden Cooling Flows in Elliptical Galaxies
L. R. Ivey, A. C. Fabian, J. S. Sanders +4
The radiative cooling time of hot gas in the cool cores of many galaxy clusters and massive elliptical galaxies drops in the centre to below 100 million years. The mass cooling rat…
Hidden Cooling Flows IV: More Details on Centaurus and the Efficiency of AGN Feedback in Clusters
A. C. Fabian, G. J. Ferland, J. S. Sanders +7
Cooling flows are common in galaxy clusters which have cool cores. The soft X-ray emission below 1 keV from the flows is mostly absorbed by cold dusty gas within the central coolin…
