AGN heating, thermal conduction and Sunyaev-Zeldovich effect in galaxy groups and clusters
S. Roychowdhury, M. Ruszkowski, B. B. Nath
(abridged) We investigate in detail the role of active galactic nuclei on the physical state of the gas in galaxy groups and clusters, and the implications for anisotropy in the CM…
Entropy "floor" and effervescent heating of intracluster gas
S. Roychowdhury, M. Ruszkowski, B. B. Nath +1
Recent X-ray observations of clusters of galaxies have shown that the entropy of the intracluster medium (ICM), even at radii as large as half the virial radius, is higher than tha…
Implications of the Universal Temperature Profile for Galaxy Clusters
Suparna Roychowdhury, Biman B. Nath
We study the X-ray cluster gas density distribution in hydrostatic equilibrium using the universal temperature profile obtained from recent simulations involving only gravitational…
Heating of the intracluster medium by quasar outflows
Biman Nath, Suparna Roychowdhury
We study the possibility of quasar outflows in clusters and groups of galaxies heating the intracluster gas in order to explain the recent observation of excess entropy in this gas…
