MS0735_CENTRAL
The MS0735 cluster's central galaxy hosts one of the largest and most mechanically-powerful radio sources known. Centered in a bright X-ray cluster, its jets have inflated two enormous cavities, each 200 kpc across, surrounded by a Mach 1.3 shock front. MS0735 (z=0.216) is among a small number of systems whose jet energetics have been measured to a precision of a factor of 2-3 using Chandra imagery, thus enabling an accurate measurement of the fraction of jet enthalpy transferred to kinetic energy in the forms of bulk and turbulent motions. A single pointing will enclose the entire system of cavities and the surrounding shock front, thus addressing the fundamental problem of how jet energy heats cluster atmospheres and prevents catastrophic cooling onto MS0735's central galaxy.
