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…
Consequences of a low-mass, high-pressure, star formation mode in early galaxies
A. C. Fabian, J. S. Sanders, G. J. Ferland +3
High resolution X-ray spectra reveal hidden cooling flows depositing cold gas at the centres of massive nearby early-type galaxies with little sign of normal star formation. Optica…
On the relation between mini-halos and AGN feedback in clusters of galaxies
A. Richard-Laferrière, J. Hlavacek-Larrondo, R. S. Nemmen +10
A variety of large-scale diffuse radio structures have been identified in many clusters with the advent of new state-of-the-art facilities in radio astronomy. Among these diffuse r…
A Multiwavelength Study of the Massive Cool Core Cluster MACS J1447.4+0827
M. Prasow-Émond, J. Hlavacek-Larrondo, C. L. Rhea +8
Clusters of galaxies are outstanding laboratories for understanding the physics of supermassive black hole feedback. Here, we present the first \textit{Chandra}, Karl G. Janksy Ver…
High-resolution VLA low radio frequency observations of the Perseus cluster: radio lobes, mini-halo and bent-jet radio galaxies
Marie-Lou Gendron-Marsolais, Julie Hlavacek-Larrondo, Reinout J. van Weeren +11
We present the first high-resolution 230-470 MHz map of the Perseus cluster obtained with the Karl G. Jansky Very Large Array. The high dynamic range and resolution achieved has al…
Do sound waves transport the AGN energy in the Perseus Cluster?
A. C. Fabian, S. A. Walker, H. R. Russell +3
The level of random motions in the intracluster gas lying between 20 and 60 kpc radius in the core of the Perseus cluster has been measured by the Hitomi Soft X-ray Spectrometer at…
Cold, clumpy accretion onto an active supermassive black hole
Grant R. Tremblay, J. B. Raymond Oonk, Françoise Combes +22
Supermassive black holes in galaxy centres can grow by the accretion of gas, liberating energy that might regulate star formation on galaxy-wide scales. The nature of the gaseous f…
X-ray Analysis of Filaments in Galaxy Clusters
S. A. Walker, P. Kosec, A. C. Fabian +1
We perform a detailed X-ray study of the filaments surrounding the brightest cluster galaxies in a sample of nearby galaxy clusters using deep Chandra observations, namely the Pers…
Implications of Coronal Line Emission in NGC 4696
M. Chatzikos, R. J. R. Williams, G. J. Ferland +7
We announce a new facility in the spectral code CLOUDY that enables tracking the evolution of a cooling parcel of gas with time. For gas cooling from temperatures relevant to galax…
The energy source of the filaments around the giant galaxy NGC1275
A. C. Fabian, J. S. Sanders, R. J. R. Williams +3
The brightest galaxy in the nearby Perseus cluster, NGC1275, is surrounded by a network of filaments. These were first observed through their Halpha emission but are now known to h…
