Heating rate profiles in galaxy clusters
Heating rate profiles in galaxy clusters
The results of hydrodynamic simulations of the Virgo and Perseus clusters
suggest that thermal conduction is not responsible for the observed temperature
and density profiles. As a result it seems that thermal conduction occurs
at a much lower level than the Spitzer value. Comparing cavity enthalpies
to the radiative losses within the cooling radius for seven clusters suggests
that some clusters are probably heated by sporadic, but extremely powerful,
AGN outflows interspersed between more frequent but lower power outflows.

Abstract
The results of hydrodynamic simulations of the Virgo and Perseus clusters
suggest that thermal conduction is not responsible for the observed temperature
and density profiles. As a result it seems that thermal conduction occurs
at a much lower level than the Spitzer value. Comparing cavity enthalpies
to the radiative losses within the cooling radius for seven clusters suggests
that some clusters are probably heated by sporadic, but extremely powerful,
AGN outflows interspersed between more frequent but lower power outflows.
