The X-ray spectrum of the cooling-flow quasar H1821+643 : A massive black hole feeding off the intracluster medium
Christopher S. Reynolds, Anne M. Lohfink, Arif Babul +4
We present a deep Suzaku observation of H1821+643, an extremely rare example of a powerful quasar hosted by the central massive galaxy of a rich cooling-core cluster of galaxies. I…
The effect of the quasar H1821+643 on the surrounding intracluster medium: revealing the underlying cooling flow
S. A. Walker, A. C. Fabian, H. R. Russell +1
We present a detailed study of the thermodynamic properties of the intracluster medium of the only low redshift galaxy cluster to contain a highly luminous quasar, H1821+643. The c…
Do high redshift quasars have powerful jets?
A. C. Fabian, S. A. Walker, A. Celotti +4
Double-lobed radio galaxies a few 100s of kpc in extent, like Cygnus A, are common at redshifts of 1 to 2, arising from some 10 per cent of the most powerful Active Galactic Nuclei…
X-ray mapping the outer regions of galaxy clusters at z= 0.23 and 0.45
Q. Daniel Wang, Stephen Walker
The thermal, chemical, and kinematic properties of the potentially multi-phase circum/inter-galactic medium at the virial radii of galaxy clusters remain largely uncertain. We pres…
