A deep dive: Chandra observations of the NGC 4839 group falling into the Coma cluster
M. S. Mirakhor, S. A. Walker, J. Runge
Cosmological simulations of structure formation predict that galaxy clusters continue to grow and evolve through ongoing mergers with group-scale systems. During these merging even…
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…
Hidden Cooling Flows in Clusters of Galaxies
A. C. Fabian, G. J. Ferland, J. S. Sanders +3
The radiative cooling time of the hot gas at the centres of cool cores in clusters of galaxies drops down to 10 million years and below. The observed mass cooling rate of such gas…
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…
A deep Chandra observation of the hot gaseous halo around a rare, extremely massive and relativistic jet launching spiral galaxy
S. A. Walker, J. Bagchi, A. C. Fabian
We present a deep Chandra observation of the extremely massive spiral galaxy 2MASX J23453268-0449256, the first X-ray observation of this very rare system which features the larges…
Exploring the origin of a large cavity in Abell 1795 using deep Chandra observations
S. A. Walker, A. C. Fabian, P. Kosec
We examine deep stacked Chandra observations of the galaxy cluster Abell 1795 (over 700ks) to study in depth a large (34 kpc radius) cavity in the X-ray emission. Curiously, despit…
