Scientific paper

Some of the first results from Chandra show that the central regions of cooling flow clusters are morphologically complex. Chandra and XMM-Newton also find little spectroscopic evidence for cool gas as expected in clusters that were previously thought to contain massive cooling flows. One possible resolution to this problem is that the gas is shocked heated by a central radio source which prevents the gas from cooling. To investigate this hypothesis, we propose to observe the cooling flow clusters A576 and A2626. The central dominant galaxy in these clusters are associated with small scale radio emission, which may indicate that the nuclear activity was triggered recently and the shock front has not yet propagated beyond the cooling flow region.
