Hot Bubbles in Cooling Flow Clusters
As more cooling flow clusters of galaxies with central radio sources are observed with the Chandra and XMM-Newton X-ray Observatories, more examples of “bubbles” (low-emission regions in the X-ray coincident with radio emission) are being found. These bubbles are surrounded by bright shells of X-ray emission, and no evidence of current strong shocks has yet been found. Using an analytic approac...
متن کاملAGN self-regulation in cooling flow clusters
We use three-dimensional high-resolution adaptive-mesh-refinement simulations to investigate if mechanical feedback from active galactic nucleus jets can halt a massive cooling flow in a galaxy cluster and give rise to a self-regulated accretion cycle. We start with a 3 × 109M⊙ black hole at the centre of a spherical halo with the mass of the Virgo cluster. Initially, all the baryons are in a h...
متن کاملCold Feedback in Cooling–Flow Galaxy Clusters
We put forward an alternative view to the Bondi–driven feedback between heating and cooling of the intra-cluster medium (ICM) in cooling flow (CF) galaxies and clusters. We adopt the popular view that the heating is due to an active galactic nucleus (AGN), i.e. a central black hole accreting mass and launching jets and/or winds. We propose that the feedback occurs with the entire cool inner reg...
متن کاملCold molecular gas in cooling flow clusters of galaxies
The results of a CO line survey in central cluster galaxies with cooling flows are presented. Cold molecular gas is detected with the IRAM 30m telescope, through CO(1-0) and CO(2-1) emission lines in 6-10 among 32 galaxies. The corresponding gas masses are between 3.10 and 4.10 M . These results are in agreement with recent CO detections by Edge (2001). A strong correlation between the CO emiss...
متن کاملSuppression of thermal conduction in non-cooling flow clusters
Recent X-ray observations have revealed a universal temperature profile of the intracluster gas of non-cooling flow clusters which is flat for r ≤ 0.2r180. Numerical simulations, however, obtain a steeper temperature profile in the inner region. We study the effect of thermal conduction on the intracluster gas in non-cooling flow clusters in light of these observations, using the steep temperat...
