A cooling flow around the low-redshift quasar H1821+643
H. R. Russell, P. E. J. Nulsen, A. C. Fabian +7
H1821+643 is the nearest quasar hosted by a galaxy cluster. The energy output by the quasar, in the form of intense radiation and radio jets, is captured by the surrounding hot atm…
AGN feedback in the Phoenix cluster
Ciro Pinto, Christopher J. Bambic, Jeremy S. Sanders +5
Active galactic nuclei (AGN) release a huge amount of energy into the intracluster medium (ICM) with the consequence of offsetting cooling and star formation (AGN feedback) in the…
Constraining gas motions in the Centaurus cluster using X-ray surface brightness fluctuations and metal diffusion
S. A. Walker, J. S. Sanders, A. C. Fabian
We compare two different methods of constraining the characteristic velocity and spatial scales of gas motions in the X-ray bright, nearby Centaurus cluster, using new deep (760ks)…
Gas Density Fluctuations in the Perseus Cluster: Clumping Factor and Velocity Power Spectrum
I. Zhuravleva, E. Churazov, P. Arevalo +9
X-ray surface brightness fluctuations in the core of the Perseus Cluster are analyzed, using deep observations with the Chandra observatory. The amplitude of gas density fluctuatio…
Turbulent Heating in Galaxy Clusters Brightest in X-rays
I. Zhuravleva, E. Churazov, A. A. Schekochihin +9
The hot, X-ray-emitting intracluster medium (ICM) is the dominant baryonic constituent of clusters of galaxies. In the cores of many clusters, radiative energy losses from the ICM…
The X-ray luminous cluster underlying the bright radio-quiet quasar H1821+643
H. R. Russell, A. C. Fabian, J. S. Sanders +4
We present a Chandra observation of the only low redshift, z=0.299, galaxy cluster to contain a highly luminous radio-quiet quasar, H1821+643. By simulating the quasar PSF, we subt…
